Evidence for Evolution Review

Front

What is the significance of the fossil record in studying evolution?

Back

It offers a chronological record of species that have existed over time, showing changes within groups and the emergence of new species.

Front

Why is embryology considered evidence for evolution?

Back

Because embryos of different species show similar stages of development, suggesting a common ancestry.

Front

How does biogeography support the theory of evolution?

Back

By illustrating how species have spread and adapted to their environments over time.

Front

What do analogous structures indicate?

Back

Similar Environment.

Front

How do homologous structures support the theory of evolution?

Back

By demonstrating that similar structures in different species were inherited from a common ancestor.

Front

What is a fossil?

Back

A fossil is the preserved remains or traces of ancient organisms, providing evidence of past life.

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 is common descent?

Back

Common descent is the concept that all living organisms share a common ancestor.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution.

Front

What is the role of mutation in evolution?

Back

Mutations are changes in DNA that can lead to new traits, providing raw material for evolution.
