6.2.0.1 Evidence of Evolution part 1

Multiple Select

A theory requires evidence. The theory of evolution is evidenced by several things which show

• change in species over generations creating new species

• new species spring from nothing

• all animals were created at the same time

Multiple Choice

Fossils are excellent places to look for evidence of evolution because fossils are

• remains of ancient life

• constantly changing

• remains of recent life

• quickly disapearing

Multiple Choice

Relative dating finds how old things are

• in exact age

• compared to something else

• by finding the year marked on the bones

Multiple Choice

Older fossils should be__________________ in the rock layers because sediment piles up on the surface

• lower

• higher

• at the same place as younger fossils

Fill in the Blanks

radioactive dating is used to find out how old a fossil is using radioactive decay. The time frame used is called the

life

Multiple Choice

Homo means same. Homologous structures have the same

• form

• function

Multiple Choice

structures with the same anatomical make up but different functions is evidence that those structures came from

• the same ancestor because structures come from our DNA

• Different ancestors because structures come from our RNA

• the same ancestors because they are used in the same way

Multiple Choice

ana is the prefix for not. Analogous structures are not

• related by form

• related by function

• important to evolution theory

Multiple Select

the Evidence for evolution discussed today included:

• Fossils

• anatomical similarities of form

• microevolution

• all birds and insects have wings
