How does natural selection lead to evolution

a species can gradually change into new species

What is gene flow

Gene flow is genes moving between two populations.

the transfer of genes from one gene pool to another

two populations transferring genes

What is an adaptation

a camel has humps to store water

a rabbit that has fur that blends in with snow

a trait that makes an organism more likely to reproduce

Why are vestigial structures not removed by natural selection

Vestigial structures do not harm the organism. Nature selects against only harmful traits.

How is radioactive dating important for providing evidence for evolution

It tells you when the animal that made a fossil was alive.

Radio carbon dating proves scientifically the age of a given material. If a fossil is found embedded in material that is x number of years old and a similar fossil is found x number of years older or younger then we can surmise the evolution of that species. There are thousands of examples of theoretical evolution using this method.

What is an effect of adaptive radiation

Speciation Adaptive radiation refers to changes in a species in response to varying environmental conditions.

many new species form
