Front

What inference can be made if modern organisms have many homologous structures?

Back

The organisms have a common ancestor.

Front

What does Darwin's theory of evolution propose about species?

Back

Species change over time.

Front

What term is used to describe the situation when all members of a species have died?

Front

What can be inferred from observing similarities in embryonic stages of different organisms?

Back

The organisms share a common ancestor.

Front

What are homologous structures?

Back

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

Front

What is the significance of fossil records in understanding evolution?

Back

Fossil records provide evidence of past organisms and their evolutionary changes.

Front

What is natural selection?

Back

A process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures share a common ancestry, while analogous structures serve similar functions but do not share a common ancestor.

Front

What is the role of mutations in evolution?

Back

Mutations introduce genetic variation, which can lead to new traits in a population.
