3 types of evolution

Evolution

organisms slowly change physical or behavioural characteristics over many generations

Speciation

Formation of new distinct species due to evolution

Distinct

Different

Speciation

The evolutionary process where one original species splits into two or more distinct, separate species due to isolation and natural selection.

If two animas have infertile offspring

They are distinct species. Two organisms of the same species would produce fertile offspring

What are the 3 different types of evolution

Convergent, divergent, coevolution

Convergent evolution

Two or more species that don’t share a common ancestor but share similar traits because they live in the same environment. This is because they develop similar characteristics to survive better in there shared environment

Example of convergent

To survive in water, both sharks and dolphin developed fins

What are the shared structures during convergent called

Analogous structures ( same function, different origin)

Divergent evolution

Two or more species come from a common ancestor, but over time the species look different from each other and eventually become a different species ( this is the process that leads to speciation)

Coevolution

The process where two or more species exert selective pressures on each other, causing them to evolve together over generations.
