Six Points of Darwin Flashcard

Front

What is Genetic Variation?

Back

Genetic Variation refers to the differences in DNA sequences among individuals within a species, leading to variations in traits.

Front

What does Overproduction mean in Darwin's theory?

Back

Overproduction is the concept that most species produce more offspring than can survive, leading to competition for resources.

Front

What is Speciation?

Back

Speciation is the evolutionary process by which populations evolve to become distinct species.

Front

Define Competition in the context of natural selection.

Back

Competition refers to the struggle between individuals or species for limited resources such as food, space, and mates.

Front

What is Temporal Isolation?

Back

Temporal Isolation is a form of reproductive isolation where species breed at different times, preventing them from mating.

Front

Explain Adaptation in relation to natural selection.

Back

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

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 role does Predation play in evolution?

Back

Predation influences evolution by selecting for traits that enhance survival, such as speed or camouflage.

Front

What is the significance of Variation in evolution?

Back

Variation is crucial for evolution as it provides the raw material for natural selection to act upon.

Front

Define the term 'Evolution'.

Back

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