Evidence for Evolution

If species do not evolve, they go __________________ .

The process of change in a species over time is called

The hip bones in a whale are examples of _________________ structures.

True/False - We can observe changes in life forms by observing the fossil record

Selection by humans for breeding of useful traits from the natural variation among different organisms

This is the study within biology that looks at where organisms live(d) past/present

Give an example of human vestigial structure

True/False - many animals have analogous structures due to common ancestry

Blind cave animals that still have eyes are an example of

A characteristic of different organisms that have similar function but not necessarily the same structure and did not come from the same common ancestor

This picture is showing an example of

This is the mechanism for evolution as proposed by Charles Darwin

True/False - Many animals have vestigial structures from an ancestor.

An example of a Homologous molecule

This is a trait that makes an organism more suited to its environment

To understand evolutionary relationships, scientists these days mostly look at _____________.

Explain the image

Overproduction, variation, adaptation, and _____________ - are the 4 conditions for natural selection to occur

The ability of an organism to survive and reproduce in its environment

Some organisms that share a common ancestor have features that have different functions, but similar structures. These are known as

The process by which unrelated organisms independently evolve similarities when adapting to similar environments

A species splits into two or more descendant species, resulting in once similar or related species to become more and more dissimilar.
