24. Evidence for Evolution

A cladogram is...

• Any remnant of a once living organism

• When 2 or more species becoming different, indicates relatedness

• Diagram that shows the evolutionary relationships among a group of organisms

• A body structure that has little or no function / use

Embryology suggests...

• Two or more species become different

• If embryos develop similarly , they likely have a common ancestor that developed that way

• Two unrelated species in similar environments become similar

• Relatedness

Structures that have little or no function / use

• Analogous Structures

• Homologous Structures

• Fossils

• Vestigial Trait

A fossil is...

• Any remnant of a once living organism

• The time it takes for half of the original amount of a radioactive element to decay

• A structures that have little or no function / use

• Diagram that shows the evolutionary relationships among a group of organisms

Same internal structures but may have different functions

• Convergent Evolution

• Divergent Evolution

• Homologous Structures

• Analogous Structures

Homologous structures indicate relatedness

• True

• False

NGSS.HS-LS4-1

Parts of different species having the same function but not the same internal structure.have evolved separately, do not share a recent common ancestor

• Convergent Evolution

• Divergent Evolution

• Homologous Structures

• Analogous Structures
