traces of organisms that lived in the past and were preserved by natural process or catastrophic events

Method is used to determining the age of rocks using the decay of radioactive isotopes of C-14 which is present in rocks when the organism died.

is the change in inherited

traits over successive generations

in populations of organisms

this change allowed organisms to adapt and survive in their environment

The body parts of organisms that may perform the same function but are of different origins

the study of the similarities and differences in the structures of different species

According to this data, the unknown bacterial species is most closely related to: 

What is the study of organisms at the early stages of development?

What is the study of organisms at the early stages of development?

Two organisms that are closely related would have

The study of the early stages of development that is one evidence of evolution is:

are shallow external molds left by animal or plant tissues with little or no organic materials present.

He is best known for his important contributions to the science of geology (uniformitarianism and the great age of the earth)

The hind (back) leg bones in this whale are:

He is the the Father of Taxonomy

The Essentialist

Some people can wiggle their ears, even though it no longer serves a purpose. This is a:

Structures that have the same function but did NOT come from a common ancestor:

TRUE or FALSE? The more differences there are in the DNA of two species, the more related they are.

What is a fossil?
