Evolution

Front

What is disruptive selection?

Back

Disruptive selection is a type of natural selection that favors extreme phenotypes over intermediate phenotypes, leading to the formation of two distinct groups within a population.

Front

Which species did Darwin study on the Galapagos Islands?

Back

Darwin studied tortoises and finches on the Galapagos Islands.

Front

What is the likely outcome when an environment changes faster than a species can adapt?

Back

The most likely outcome is species extinction.

Front

Which organism is the most distantly related to others: Raccoon, Dog, Giant Panda, or Sun Bear?

Back

Dog is the most distantly related organism among the options.

Front

What accounts for the similarity in limb structures among different species?

Back

They came from the same source, indicating a common ancestor.

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

Define evolution.

Back

Evolution is the change in the heritable characteristics of biological populations over successive generations.

Front

What is a common ancestor?

Back

A common ancestor is an ancestral species from which two or more different species have evolved.

Front

What is the significance of genetic variation in evolution?

Back

Genetic variation is crucial for natural selection, as it provides the raw material for evolution by allowing some individuals to be better suited to their environment.

Front

What is speciation?

Back

Speciation is the process by which new species arise from existing species.
