Back

Layer E is the oldest layer.

Front

What type of evolutionary evidence do bird and butterfly wings represent?

Back

Analogous structures.

Front

How can we determine the closest relation between bacterial species?

Back

By comparing their genetic data.

Front

Which areas provide the best evidence for common ancestry?

Back

Areas 1 and 2.

Front

What does a greater number of differences in DNA base pairs indicate about two organisms?

Back

They are more distantly related.

Front

What are homologous structures?

Back

Structures in different species that are similar due to shared ancestry.

Front

What are analogous structures?

Back

Structures that serve similar functions but have different evolutionary origins.

Front

What is embryological development evidence in evolution?

Back

Similarities in embryonic stages among different species indicate common ancestry.

Front

What is the significance of fossil records in evolution?

Back

Fossil records provide evidence of how species have changed over time.

Front

What is genetic comparison in evolutionary biology?

Back

Analyzing DNA sequences to determine the evolutionary relationships between organisms.
