Answer 1
One species can evolve from two species if the two bypass the barriers between them. These barriers can be physical. For example, mountains or if they are similar in type. A plant can not breed with a human, there are too many genetic differences. If their offspring can interbreed or have offspring of their own they can form a new species. Horses and donkeys are close in genetic type but their offspring are mules and they are infertile and can not have offspring of their own.
Answer 2
As noted above, a new species may emerge from a hybridisation between two closely related existing species. This is not seen very often in the more complex animals, but happens frequently in plants and may occasionally occur in insects or even birds.
When two species evolve together, it is known as coevolution. This process involves reciprocal evolutionary changes that occur in response to one another, often in a tightly interconnected relationship. Coevolution can lead to specialized adaptations and mutualistic interactions between the two species.
When two species compete for the same resources and later evolve separate anatomical specializations that reduce interspecific competition the result is character displacement.
Convergent evolution: Unrelated species develop similar traits in response to similar environmental pressures. Divergent evolution: Related species evolve different traits over time due to adapting to different environments. Coevolution: Two species evolve in response to each other, often developing specialized relationships. Parallel evolution: Two related species evolve similar traits independently. Adaptive radiation: An evolutionary process where one species diversifies into multiple new species in different ecological niches. Punctuated equilibrium: Evolutionary changes occur rapidly in short bursts, interspersed with periods of stability.
When two organisms occupy the same niche, they compete for the same resources like food, shelter, and mates. This competition can lead to one species outcompeting the other. Over time, one species may adapt to a different niche or evolve specialized traits to reduce direct competition.
The five types of evolution are divergent evolution (species diverge from a common ancestor), convergent evolution (unrelated species develop similar traits), coevolution (two species evolve in response to each other), parallel evolution (related species independently evolve similar traits), and adaptive radiation (rapid diversification of species to fill ecological niches).
they both die
When two groups of the same species are cut off from each other, they evolve from mutations and natural selection independently. Each one could evolve into a different species. For instance, let's say two populations of a species of bunny exist, one in a desert and one in the artic. The one in the desert would likely evolve into a bunny which could keep cool and blend into rocks and sand, while the population in the artic would likely evolve into a species which could keep warm and blend into snow. The one species of bunny would then become two.
This is an occurrence of co-evolution of the two species.
If there is multiple environments and competition for food, there will be more species development.
This is when one animal will evolve into two different species. Many animals and insects will do this in certain areas.
Parallel evolution: two (or more) species or genera that evolve in similar ways over time. Divergent evolution: two or more closely related species or genera that evolve to become quite different from one another. Convergent evolution: two or more unrelated and dissimilar species or genera that evolve to become similar to one another, for example penguins (birds that used to fly), dolphins (mammals that used to walk on land) and fish (animals that were always swimming)
its convergance actually its co-evolution. convergence is when unrelated organisms come to resemble one another. co-evolution is the process in which two species evolve in response to changes in each other over time.
When two species evolve together, it is known as coevolution. This process involves reciprocal evolutionary changes that occur in response to one another, often in a tightly interconnected relationship. Coevolution can lead to specialized adaptations and mutualistic interactions between the two species.
According to the competitive exclusion principle, two species cannot continue to occupy the same ecological niche in a community because one will outcompete the other leading to the elimination of the less adapted species.
When two species compete for the same resources and later evolve separate anatomical specializations that reduce interspecific competition the result is character displacement.
A common speciation event is called allopactric speciation. This is the geographic separation of a single species into two populations. Naturally, one could expect statistically different genetic variation to arise in these two populations and the environments may be different also. In any event, these two populations, after time, would be headed down different evolutionary roads.
Convergent evolution: Unrelated species develop similar traits in response to similar environmental pressures. Divergent evolution: Related species evolve different traits over time due to adapting to different environments.
