Evolution

Front

What does embryonic development similarity suggest about organisms?

Back

They have a common ancestor.

Front

Who is the scientist known for the theory of natural selection?

Back

Charles Darwin.

Front

What is a fossil?

Back

A trace of an organism that existed in the past.

Front

How does natural selection contribute to the evolution of new species?

Back

The organisms that are best adapted to their environment will survive long enough to pass on their genetic traits to future generations.

Front

What are homologous structures?

Back

Features that have different functions but similar structures, indicating a common ancestor.

Front

What is natural selection?

Back

The process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What are vestigial structures?

Back

Structures that have lost most or all of their original function through the course of evolution.

Front

What is the significance of the Galapagos Islands in evolutionary biology?

Back

They were studied by Charles Darwin, leading to the development of his theory of natural selection.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures share a common ancestry but have different functions; analogous structures have similar functions but do not share a common ancestry.

Front

What role do mutations play in evolution?

Back

Mutations introduce genetic variation, which can be acted upon by natural selection.
