Evidence of Evolution 3

Front

Which layer is the youngest in a geological formation?

Back

The youngest layer is the one that is most recently deposited, typically found at the top of the sequence.

Front

What do similar bones in different species indicate?

Back

Similar bones indicate a common ancestor, suggesting evolutionary relationships.

Front

Which layer is the oldest in a geological formation?

Back

The oldest layer is the one that was deposited first, typically found at the bottom of the sequence.

Front

What is the term for the changes of species over time?

Back

Evolution.

Front

What is a vestigial structure?

Back

A vestigial structure is a body part that has lost its original function through the course of evolution.

Front

What is a homologous structure?

Back

A homologous structure is an anatomical feature in different species that is similar due to shared ancestry.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What evidence supports the theory of evolution?

Back

Fossil records, genetic similarities, and anatomical comparisons provide evidence for evolution.

Front

What is embryonic development evidence in evolution?

Back

Embryonic development shows similarities in early stages among different species, indicating common ancestry.

Front

What is mimicry in evolutionary terms?

Back

Mimicry is when one species evolves to resemble another species for protection or other advantages.
