What did Lamarck believe about giraffes' necks?

they stretched their necks to reach trees

Why are mutations important to natural selection?

It gives nature different variations/traits to pick from.

Natural selection increases the frequency of:

Traits that make individuals better adapted

Owls camouflage. What would Darwin say about this?

animals that camouflage the best will survive

Charles Darwin observed . . .

similar species with traits that suited their environment

In what way is natural selection random?

Many traits that help organisms evolve come from mutations

millions of fossils that scientist have collected

A common ancestor is...

when two species came from the same common species

Why are mutations important to natural selection?
It causes individuals to change.
It lets an organism change its DNA to be more adaptive.
It gives nature different variations/traits to pick from.
It causes genetic disorders, killing an entire population- extinction.
