Natural Selection

Front

What is Natural Selection?

Back

Natural selection is the process by which organisms that are better adapted to their environment tend to survive and produce more offspring.

Front

What are the mechanisms of natural selection?

Back

The mechanisms include overproduction of offspring, competition for resources, variation among individuals, and survival of the fittest.

What is an example of behavioral adaptation?

Back

Hibernation in animals is an example of behavioral adaptation, allowing them to survive in harsh conditions.

Front

What is a structural adaptation?

Back

A structural adaptation is a physical feature of an organism that enhances its survival, such as the large eyes of nocturnal animals.

What is the significance of fossils in understanding evolution?

Back

Fossils provide evidence of past life forms and show how species have changed over time.

Front

What does genetic evidence for evolution include?

Back

Genetic evidence includes similarities in DNA sequences among different species, indicating common ancestry.

Front

What is the role of predators in natural selection?

Back

Predators can influence which traits are favorable, leading to changes in the population over time.

Front

What is the concept of 'survival of the fittest'?

Back

'Survival of the fittest' refers to the idea that individuals with advantageous traits are more likely to survive and reproduce.

Front

How can environmental changes affect a species?

Back

Environmental changes can alter the availability of resources, leading to shifts in population dynamics and adaptations.

Front

What is an example of a population evolving due to disease?

Back

If some rabbits are resistant to a disease, they may survive and reproduce, leading to a population that is more resistant over time.
