Evolution Test Review

Front

What is evolution?

Back

Evolution is the process through which species change over time through variations and natural selection.

Front

What is natural selection?

Back

Natural selection is the mechanism by which individuals with favorable traits are more likely to survive and reproduce.

Front

Define inherited variations.

Back

Inherited variations are differences in traits that are passed from parents to offspring, which can affect survival and reproduction.

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various species based on shared characteristics.

Front

What is overpopulation?

Back

Overpopulation occurs when a species' population exceeds the carrying capacity of its environment.

Front

What is adaptation?

Back

Adaptation is a trait that enhances an organism's ability to survive and reproduce in its environment.

Front

What role do mutations play in evolution?

Back

Mutations are changes in DNA that can lead to new traits, which may be beneficial, harmful, or neutral in terms of survival.

Front

What is the significance of competition in ecosystems?

Back

Competition among species for resources can drive natural selection and influence population dynamics.

Front

How does predation affect population dynamics?

Back

Predation can regulate prey populations, leading to evolutionary changes in both predator and prey species.

Front

What is the difference between a species and a population?

Back

A species is a group of organisms that can interbreed, while a population is a group of individuals of the same species living in a specific area.
