Evolution and Natural Selection

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism's genome that can lead to new traits.

Front

How do mutations contribute to evolution?

Back

Mutations can create new traits that may be beneficial, allowing organisms to adapt and evolve over time.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What does 'evolution' mean?

Back

Evolution refers to the genetic change in a population over time.

Front

What is an adaptive trait?

Back

An adaptive trait is a characteristic that enhances an organism's ability to survive and reproduce in its environment.

Front

What is the significance of a common ancestor in evolution?

Back

A common ancestor indicates that different species share a lineage and have evolved from a single species over time.

Front

What is the role of competition in natural selection?

Back

Competition for resources leads to the survival of the fittest, where only the organisms best suited to their environment survive.

Front

What evidence supports the theory of evolution?

Back

Fossil records, genetic similarities, and anatomical structures provide evidence that species have evolved over time.

Front

What is speciation?

Back

Speciation is the process by which new species arise from existing species due to evolutionary changes.

Front

What is fitness in the context of evolution?

Back

Fitness refers to an organism's ability to survive and reproduce in its environment.
