Why might the organism evolve into two different species?

Even if organisms of different species combine their DNA to make offspring, the offspring will be sterile, unable to pass on their genes. Because of this restricted gene flow, each species evolves as a group distinct from other species.

Can two different species evolve into the same species?

Two species usually can’t coevolve to become one “species” (they will never be able to directly interbreed) but they can coevolve to become one organism which, given enough time might develop into a situation where reproduction of the “host” organism includes reproduction/spreading of the other organism to the new ” …

What is it called when two different species evolve in similar ways?

Convergent evolution occurs when species occupy similar ecological niches and adapt in similar ways in response to similar selective pressures. Traits that arise through convergent evolution are referred to as ‘analogous structures’.

What caused the different species to evolve separately from each other if they lived on the same islands?

Each island has a different environment. The differences in environment selected different variates from the possibilities of the DNA in the finches. Also within a given island there are different niches. For example on the same island there are three different species of ground finches.

How do different species evolve?

All organisms, including humans, evolve over time. Evolution occurs through natural selection, and is a force that has shaped every organism living today.

Why might different species in the same environment share some traits?

When two different species share a lot of traits, it’s known as morphological similarity. The simple reason for parallel evolution occuring is that similar environments and similar population pressures do indeed lead different species to evolve similar traits.

What is it called when two species become one?

Despeciation is the loss of a unique species of animal due to its combining with another previously distinct species.

What are some reasons that similar traits might arise independently in species that are only distantly related?

What are some reasons that similar traits might arise independently in species that are only distantly related? Can you think of examples among familiar organisms? A reason that they might arise independently is because of convergent evolution.

What happens when two groups become two different species?

Each group changes in different ways. Eventually, the two groups are so different that they can’t breed to produce offspring any more. They have become two different species. Species eventually become extinct. That means that the population gets smaller and smaller, until no more organisms of that species are left alive.

Will humans evolve into another species in the future?

Humans will change in the future, but are unlikely to evolve into a new, separate species because no human group is truly isolated anymore, given our transportation systems. Without genetic isolation, there is no further opportunity for speciation among humans. 6. If humans evolved from apes then why are there still apes?

How do biologists believe that new species evolve from existing species?

Biologists believe that new species evolve from existing species by a process called natural selection. Here’s how it works. Genes are chemical structures in the cells of the organism. The nature of the organism is determined by its genes. The organism inherits the genes from its parents. Occasionally a gene changes accidentally.

How do changes in the environment affect evolution?

If the environment changes slowly enough, species will sometimes evolve the necessary adaptations, over many generations. If conditions change more quickly than a species can evolve, however, and if members of that species lack the traits they need to survive in the new environment, the likely result will be extinction.
