Nov. Auf jeder Karte gibt es in Battlefield 4 sogenannte Levolution-Ereignisse. Diese verändern die Umgebung oder sogar die gesamte Karte, was. Levolution is an all-in-one platform that makes it easy for blockchain entrepreneurs to create, develop, market, and optimize ITO projects. In addition to . Levolution ist ein neues Feature in der Battlefield Serie und kommt zum ersten Mal auf den Multiplayerkarten in Battlefield 4 zum Einsatz. Es handelt sich um ein .
These pipes are located in two separate underground rooms in the middle of the main street near Flag B and Flag D Conquest.
Use the control panel on the pipes to increase and decrease the pressure, but both must be increased for this to work. A giant explosion will go along the main street from Flag B to D, demolishing the bridge over Flag C and creating a large trench along the middle of the street.
The largest levolution change on Flood Zone occurs after breaking the levee at the northern part of the map. More specifically, the break-able part is located to the north of Flag B, and will always have water squirting out of it.
Use a number of explosives until the whole levee busts. Water will flood the entire map, preventing the use of most vehicles.
Infantry must stick to high ground while boats rule the streets. The largest levolution change on Hainan Resort occurs after destroying part of the hotel at Flag B.
Destroy the first two ground floors on either the left or right side of the hotel to demolish the left or right side of the building.
This will cut some routes off while opening others to the higher floors in the hotel. The largest levolution change on Lancang Dam occurs after destroying the dam on the northern part of the map.
Use a number of explosives to damage the middle of the map. Eventually, the middle of the dam will crumble, blocking the northern road.
The largest levolution change on Operation Locker occurs after destroy the guard tower at Flag C. Use a number of explosives to damage the tower until it collapses.
The Flag will be set under the collapsed tower after the destruction, and a path will open between the two floors.
The largest levolution change on Paracel Storm occurs after the windmill near the large ship is destroyed by Flag C.
After the weather turns bad, the windmill near Flag C will catch on fire. Destroy this windmill using a number of explosives and vehicle weapons.
The ship will move towards Flag C and comes ashore, destroying the building near the Flag. Everyone will then have access to the Stationary Anti-Air vehicle on the deck of the ship.
The largest levolution change on Rogue Transmission occurs after snapping the support cables that hold the giant dish together.
Destroy two of the three support cable groups on the map to partially destroy the large dish. These outcomes of evolution are distinguished based on time scale as macroevolution versus microevolution.
Macroevolution refers to evolution that occurs at or above the level of species, in particular speciation and extinction; whereas microevolution refers to smaller evolutionary changes within a species or population, in particular shifts in allele frequency and adaptation.
For instance, a large amount of variation among individuals allows a species to rapidly adapt to new habitats , lessening the chance of it going extinct, while a wide geographic range increases the chance of speciation, by making it more likely that part of the population will become isolated.
In this sense, microevolution and macroevolution might involve selection at different levels—with microevolution acting on genes and organisms, versus macroevolutionary processes such as species selection acting on entire species and affecting their rates of speciation and extinction.
A common misconception is that evolution has goals, long-term plans, or an innate tendency for "progress", as expressed in beliefs such as orthogenesis and evolutionism; realistically however, evolution has no long-term goal and does not necessarily produce greater complexity.
Adaptation is the process that makes organisms better suited to their habitat. By using the term adaptation for the evolutionary process and adaptive trait for the product the bodily part or function , the two senses of the word may be distinguished.
Adaptations are produced by natural selection. Adaptation may cause either the gain of a new feature, or the loss of an ancestral feature.
An example that shows both types of change is bacterial adaptation to antibiotic selection, with genetic changes causing antibiotic resistance by both modifying the target of the drug, or increasing the activity of transporters that pump the drug out of the cell.
Adaptation occurs through the gradual modification of existing structures. Consequently, structures with similar internal organisation may have different functions in related organisms.
This is the result of a single ancestral structure being adapted to function in different ways. The bones within bat wings, for example, are very similar to those in mice feet and primate hands, due to the descent of all these structures from a common mammalian ancestor.
During evolution, some structures may lose their original function and become vestigial structures. Examples include pseudogenes ,  the non-functional remains of eyes in blind cave-dwelling fish,  wings in flightless birds,  the presence of hip bones in whales and snakes,  and sexual traits in organisms that reproduce via asexual reproduction.
However, many traits that appear to be simple adaptations are in fact exaptations: However, in this species, the head has become so flattened that it assists in gliding from tree to tree—an exaptation.
An area of current investigation in evolutionary developmental biology is the developmental basis of adaptations and exaptations. Interactions between organisms can produce both conflict and cooperation.
When the interaction is between pairs of species, such as a pathogen and a host , or a predator and its prey, these species can develop matched sets of adaptations.
Here, the evolution of one species causes adaptations in a second species. These changes in the second species then, in turn, cause new adaptations in the first species.
This cycle of selection and response is called coevolution. In this predator-prey pair, an evolutionary arms race has produced high levels of toxin in the newt and correspondingly high levels of toxin resistance in the snake.
Not all co-evolved interactions between species involve conflict. For instance, an extreme cooperation exists between plants and the mycorrhizal fungi that grow on their roots and aid the plant in absorbing nutrients from the soil.
Here, the fungi actually grow inside plant cells, allowing them to exchange nutrients with their hosts, while sending signals that suppress the plant immune system.
Coalitions between organisms of the same species have also evolved. An extreme case is the eusociality found in social insects, such as bees , termites and ants , where sterile insects feed and guard the small number of organisms in a colony that are able to reproduce.
Here, somatic cells respond to specific signals that instruct them whether to grow, remain as they are, or die. If cells ignore these signals and multiply inappropriately, their uncontrolled growth causes cancer.
Speciation is the process where a species diverges into two or more descendant species. There are multiple ways to define the concept of "species.
Despite the diversity of various species concepts, these various concepts can be placed into one of three broad philosophical approaches: Defined by evolutionary biologist Ernst Mayr in , the BSC states that "species are groups of actually or potentially interbreeding natural populations, which are reproductively isolated from other such groups.
Barriers to reproduction between two diverging sexual populations are required for the populations to become new species.
Gene flow may slow this process by spreading the new genetic variants also to the other populations. Depending on how far two species have diverged since their most recent common ancestor , it may still be possible for them to produce offspring, as with horses and donkeys mating to produce mules.
In this case, closely related species may regularly interbreed, but hybrids will be selected against and the species will remain distinct.
However, viable hybrids are occasionally formed and these new species can either have properties intermediate between their parent species, or possess a totally new phenotype.
Speciation has been observed multiple times under both controlled laboratory conditions see laboratory experiments of speciation and in nature.
There are four primary geographic modes of speciation. The most common in animals is allopatric speciation , which occurs in populations initially isolated geographically, such as by habitat fragmentation or migration.
Selection under these conditions can produce very rapid changes in the appearance and behaviour of organisms. The second mode of speciation is peripatric speciation , which occurs when small populations of organisms become isolated in a new environment.
This differs from allopatric speciation in that the isolated populations are numerically much smaller than the parental population.
Here, the founder effect causes rapid speciation after an increase in inbreeding increases selection on homozygotes, leading to rapid genetic change.
The third mode is parapatric speciation. This is similar to peripatric speciation in that a small population enters a new habitat, but differs in that there is no physical separation between these two populations.
Instead, speciation results from the evolution of mechanisms that reduce gene flow between the two populations.
One example is the grass Anthoxanthum odoratum , which can undergo parapatric speciation in response to localised metal pollution from mines.
Selection against interbreeding with the metal-sensitive parental population produced a gradual change in the flowering time of the metal-resistant plants, which eventually produced complete reproductive isolation.
Selection against hybrids between the two populations may cause reinforcement , which is the evolution of traits that promote mating within a species, as well as character displacement , which is when two species become more distinct in appearance.
Finally, in sympatric speciation species diverge without geographic isolation or changes in habitat. This form is rare since even a small amount of gene flow may remove genetic differences between parts of a population.
One type of sympatric speciation involves crossbreeding of two related species to produce a new hybrid species.
This is not common in animals as animal hybrids are usually sterile. This is because during meiosis the homologous chromosomes from each parent are from different species and cannot successfully pair.
However, it is more common in plants because plants often double their number of chromosomes, to form polyploids.
Speciation events are important in the theory of punctuated equilibrium , which accounts for the pattern in the fossil record of short "bursts" of evolution interspersed with relatively long periods of stasis, where species remain relatively unchanged.
As a result, the periods of stasis in the fossil record correspond to the parental population and the organisms undergoing speciation and rapid evolution are found in small populations or geographically restricted habitats and therefore rarely being preserved as fossils.
Extinction is the disappearance of an entire species. Extinction is not an unusual event, as species regularly appear through speciation and disappear through extinction.
The role of extinction in evolution is not very well understood and may depend on which type of extinction is considered. The Earth is about 4.
Microbial mat fossils have been found in 3. More than 99 percent of all species, amounting to over five billion species,  that ever lived on Earth are estimated to be extinct.
Highly energetic chemistry is thought to have produced a self-replicating molecule around 4 billion years ago, and half a billion years later the last common ancestor of all life existed.
All organisms on Earth are descended from a common ancestor or ancestral gene pool. First, they have geographic distributions that cannot be explained by local adaptation.
Second, the diversity of life is not a set of completely unique organisms, but organisms that share morphological similarities.
Third, vestigial traits with no clear purpose resemble functional ancestral traits and finally, that organisms can be classified using these similarities into a hierarchy of nested groups—similar to a family tree.
Past species have also left records of their evolutionary history. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record.
However, this approach is most successful for organisms that had hard body parts, such as shells, bones or teeth. Further, as prokaryotes such as bacteria and archaea share a limited set of common morphologies, their fossils do not provide information on their ancestry.
More recently, evidence for common descent has come from the study of biochemical similarities between organisms.
For example, all living cells use the same basic set of nucleotides and amino acids. Prokaryotes inhabited the Earth from approximately 3—4 billion years ago.
The next major change in cell structure came when bacteria were engulfed by eukaryotic cells, in a cooperative association called endosymbiosis.
The history of life was that of the unicellular eukaryotes, prokaryotes and archaea until about million years ago when multicellular organisms began to appear in the oceans in the Ediacaran period.
Soon after the emergence of these first multicellular organisms, a remarkable amount of biological diversity appeared over approximately 10 million years, in an event called the Cambrian explosion.
Here, the majority of types of modern animals appeared in the fossil record, as well as unique lineages that subsequently became extinct.
About million years ago, plants and fungi colonised the land and were soon followed by arthropods and other animals.
Concepts and models used in evolutionary biology, such as natural selection, have many applications. Artificial selection is the intentional selection of traits in a population of organisms.
This has been used for thousands of years in the domestication of plants and animals. Proteins with valuable properties have evolved by repeated rounds of mutation and selection for example modified enzymes and new antibodies in a process called directed evolution.
Breeding together different populations of this blind fish produced some offspring with functional eyes, since different mutations had occurred in the isolated populations that had evolved in different caves.
Evolutionary theory has many applications in medicine. Many human diseases are not static phenomena, but capable of evolution. Viruses, bacteria, fungi and cancers evolve to be resistant to host immune defences , as well as pharmaceutical drugs.
It is possible that we are facing the end of the effective life of most of available antibiotics  and predicting the evolution and evolvability  of our pathogens and devising strategies to slow or circumvent it is requiring deeper knowledge of the complex forces driving evolution at the molecular level.
In computer science , simulations of evolution using evolutionary algorithms and artificial life started in the s and were extended with simulation of artificial selection.
He used evolution strategies to solve complex engineering problems. In the 19th century, particularly after the publication of On the Origin of Species in , the idea that life had evolved was an active source of academic debate centred on the philosophical, social and religious implications of evolution.
Today, the modern evolutionary synthesis is accepted by a vast majority of scientists. While various religions and denominations have reconciled their beliefs with evolution through concepts such as theistic evolution , there are creationists who believe that evolution is contradicted by the creation myths found in their religions and who raise various objections to evolution.
The teaching of evolution in American secondary school biology classes was uncommon in most of the first half of the 20th century.
The Scopes Trial decision of caused the subject to become very rare in American secondary biology textbooks for a generation, but it was gradually re-introduced later and became legally protected with the Epperson v.
Since then, the competing religious belief of creationism was legally disallowed in secondary school curricula in various decisions in the s and s, but it returned in pseudoscientific form as intelligent design ID , to be excluded once again in the Kitzmiller v.
