As a result of their traits increasing their chances of survival and reproduction.
What is the main concept of natural selection as described in the text?
Individuals with heritable traits better suited to their environment tend to survive and reproduce.
How did Gregor Mendel contribute to the understanding of heredity?
By conducting experiments on pea plants that provided evidence for a mechanism of heredity.
Why did Darwin's observations include the fact that individuals within a population often vary greatly in their traits?
To show that variations in traits can lead to natural selection and adaptation over time.
What key factor contributes to the increase in frequency of favorable adaptations in a population over time according to the text?
Natural selection favoring individuals with traits better suited for the environment.
