Day 9 Unit 7: Natural Selection Review (Thursday, 3-23-23)

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 does 'Survival of the Fittest' mean?

Back

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

Front

What is evolution?

Back

Evolution is the genetic change in a population over time.

Front

What are mutations?

Back

Mutations are changes in the DNA sequence that can lead to variations in traits.

Front

What is variation in a species?

Back

Variation refers to the differences in traits among individuals of the same species.

Front

What is fitness in the context of natural selection?

Back

Fitness refers to an organism's ability to survive and reproduce in its environment.

Front

What is the role of DNA in evolution?

Back

DNA carries genetic information that can mutate and lead to evolutionary changes.

Front

How do advantageous traits affect reproduction?

Back

Advantageous traits increase the likelihood of survival and reproduction, leading to those traits being passed on to offspring.

Front

What is the significance of genetic diversity?

Back

Genetic diversity increases a population's ability to adapt to changing environments.

Front

What is speciation?

Back

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