What is an ancient species from which two or more species evolved?

What is an ancient species from which two or more species evolved?

Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time.

What does it mean to say that species evolved?

Evolution is the process by which species adapt over time in response to their changing environment.

How could two species that evolved on separate continents have many similarities?

How could two species that evolved on separate continents have many similarities? Land bridges. Geographic isolation is when two species are separated and both of them have to adapt to their new habitats.

What is the difference between species and speciation?

In some case, organisms of different species can mate and produce healthy offspring, but the offspring are infertile, can’t reproduce. For example, when a female horse and a male donkey mate, they produce hybrid offspring called mules.

Why do species diverge?

Genetic divergence happens because of natural selection, which may favor different traits in each environment, and other evolutionary forces like genetic drift. As they diverge, the groups may evolve traits that act as prezygotic and/or postzygotic barriers to reproduction.

What are the two iconic creatures that relate to the theory of evolution?

Summary: Darwin’s finches, inhabiting the Galapagos archipelago and Cocos island, constitute an iconic model for studies of speciation and adaptive evolution.

What most likely caused the variations in these finches?

What most likely caused the finches on the Galapagos Islands to have beaks that were different from the finches on the mainland? There were different types of predators on the island. There were different types of food available on the island.

How is speciation an outcome of divergent evolution?

Each time one ancestral species diverges into multiple descendant species it is called speciation. Speciation is an important outcome of divergent evolution. Of course, divergent evolution doesn’t have to take place on such a noble scale. It can also be as simple as different populations of an organism that have shaped different environments.

Which is an example of convergent or divergent evolution?

Convergent evolution is the procedure where two or different species evolve similar traits, in spite of having a distinct ancestor. An example is wings of birds, bats, insects. While Divergent evolution is rising to new species which may be identical in function but morphologically disparate from their ancestors.

How are different species related to each other?

Different species in similar locations would appear more closely related than the same species that occurred in different locations. Horizontal gene transfer can occur between only individuals of the same species. only one bacteria and another.

How is parallel evolution similar to divergent evolution?

Parallel evolution is the development of a similar trait in species descending from the same ancestor. It is similar to divergent evolution in that the species descend from the same ancestor, but it differs in that the trait is the same while in divergent evolution the trait is not.
