Five Fingers of Evolution

Front

What does the pinky finger represent in the Five Fingers of Evolution?

Back

Population shrinks (bottleneck effect)

Front

What mechanism of evolution is represented by the thumb?

Back

Natural selection

Front

What does the pointer finger represent in the Five Fingers of Evolution?

Back

Gene flow

Front

How does the middle finger symbolize mutations?

Back

It has an 'm' within the fingerprint, which stands for mutations.

Front

What is the role of natural selection in evolution?

Back

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

Front

Define gene flow in the context of evolution.

Back

Gene flow is the transfer of genetic variation from one population to another.

Front

What is the significance of mutations in evolution?

Back

Mutations introduce new genetic variations, which can lead to new traits in a population.

Front

Explain the concept of non-random mating.

Back

Non-random mating occurs when individuals select mates based on specific traits, affecting the genetic structure of the population.

Front

What is the bottleneck effect?

Back

The bottleneck effect is a sharp reduction in the size of a population due to environmental events, leading to a loss of genetic diversity.

Front

How does natural selection differ from genetic drift?

Back

Natural selection is a process driven by environmental pressures, while genetic drift is a random process that affects allele frequencies in a population.
