Evolution

Front

What is evolution?

Back

Evolution is the process through which species change over time through adaptations and genetic changes.

Front

True or False: Individuals undergo evolution.

Back

False. Evolution occurs at the population level, not at the individual level.

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

Which group are primates most closely related to according to cladograms?

Back

Primates are most closely related to rodents and rabbits.

Front

What is the founder effect?

Back

The founder effect is a genetic phenomenon that occurs when a small group of individuals establishes a new population, leading to reduced genetic diversity.

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population.

Front

How does a species change over time?

Back

A species changes over time through changes in gene frequencies in a population.

Front

What is the most specific category in taxonomy?

Back

The most specific category in taxonomy is 'Species'.

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 adaptation in the context of evolution?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.
