Evolution Test

Front

What is stabilizing selection?

Back

A type of natural selection that favors average phenotypes in a population, reducing variation and maintaining the status quo.

Front

What are the most studied animals in the Galapagos Islands?

Back

Finches.

Front

What does 'survival of the fittest' mean?

Back

It refers to the process where individuals with traits better suited for their environment are more likely to survive and reproduce.

Front

What is directional selection?

Back

A type of natural selection that favors one extreme phenotype over others, leading to a shift in the population's traits.

Front

What is disruptive selection?

Back

A type of natural selection that favors extreme phenotypes at both ends of the spectrum, leading to increased variation.

Front

What is genetic drift?

Back

A random process that can cause changes in allele frequencies in a population, especially in small populations.

Front

What is allopatric speciation?

Back

The process of speciation that occurs when populations are geographically isolated from each other.

Front

What is a normal distribution?

Back

A probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence.

Front

What is the role of mutations in evolution?

Back

Mutations introduce new genetic variations, which can lead to new traits that may be beneficial for survival.

Front

What is natural selection?

Back

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