Analogous vs Homologous

Front

What is a Vestigial Structure?

Back

Genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species.

Front

Structures that are inherited from a common ancestor are homologous. True or False?

Back

True

Front

How would you describe structures that have different functions but similar structures due to common ancestry?

Back

Homologous structures.

Front

Analogous structures show common ancestry. True or False?

Back

False.

Front

What are structures that have a common function but do not share a common ancestry?

Back

Analogous structures.

Front

What is the main difference between homologous and analogous structures?

Back

Homologous structures share a common ancestry, while analogous structures do not.

Front

Give an example of a homologous structure in vertebrates.

Back

The forelimbs of humans, whales, and bats.

Front

What is an example of an analogous structure?

Back

The wings of birds and insects.

Front

What do homologous structures suggest about the organisms that possess them?

Back

They suggest a common evolutionary ancestor.

Front

What is the significance of vestigial structures in evolutionary biology?

Back

They provide evidence for evolution by showing traits that were once functional in ancestors.
