Natural Selection

Front

What is evolution by natural selection?

Back

A process where organisms with adaptations compete better for resources, survive longer, and pass those adaptations to their offspring.

Front

What factors are involved in natural selection?

Back

1. Individuals of species compete with one another to survive. 2. All species are genetically diverse. 3. Individuals better able to adapt to changes leave more offspring.

Front

How does evolution occur?

Back

Through small changes passed down through many generations.

Front

What is adaptation?

Back

Beneficial traits that allow organisms to survive and pass on those traits to their offspring.

What happens to a herd of goats that can eat poison ivy over time?

Back

Front

Define natural selection.

Back

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

Front

What is genetic diversity?

Back

The variety of genes within a species, which is crucial for natural selection.

Front

Explain the term 'survival of the fittest'.

Back

A phrase that describes the mechanism of natural selection, where the fittest individuals are more likely to survive and reproduce.

Front

What role does competition play in natural selection?

Back

Competition for resources leads to the survival of individuals with advantageous traits.

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to new traits in an organism.
