Five Fingers of Evolution

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 gene flow?

Back

Gene flow is the transfer of genetic material between populations, which can occur through immigration (genes coming in) and emigration (genes leaving).

Front

What does non-random mating mean?

Back

Non-random mating refers to the process where individuals select mates based on specific traits, rather than mating randomly.

Front

What is evolution?

Back

Evolution is the change in the gene pool of a population over time, often due to natural selection, mutations, gene flow, and non-random mating.

Front

How do mutations contribute to evolution?

Back

Mutations are changes in the DNA sequence that can introduce new traits into a population, which may be beneficial, harmful, or neutral.

Front

What is the significance of the 'thumb' in the Five Fingers of Evolution?

Back

The 'thumb' represents natural selection, which is a key mechanism driving evolution.

Front

What role do mutations play in the Five Fingers of Evolution?

Back

Mutations are represented by the 'middle finger' and are essential for introducing genetic variation in a population.

Front

What is the 'pointer finger' in the Five Fingers of Evolution?

Back

The 'pointer finger' represents non-random mating, highlighting the importance of mate selection in evolution.

Front

What does the 'ring finger' symbolize in the Five Fingers of Evolution?

Back

The 'ring finger' symbolizes gene flow, indicating how genetic material can move between populations.

Front

What is the 'pinky finger' in the Five Fingers of Evolution?

Back

The 'pinky finger' represents genetic drift, which is the change in allele frequencies due to random sampling effects.
