FACT 1 : Individuals in a population vary or differ in traits. Most of this variation is heritable (passed from parent to offspring).

FACT 2 : A population of any species has the potential to produce far more offspring than will survive to produce offspring of their own. What are some of the challenges living things must overcome to survive?

Слайд 10

Inference 1 : Certain inherited variations give some individuals a better chance to survive in their environment. Those that survive will produce more offspring. This is called natural selection.

Слайд 11

Inference 2 : Each generation will contain a greater percentage of individuals with these favorable traits leading to a change in the average characteristics of a population over time. This is called evolution.

Слайд 12: Grant Finch Study: state and explain the specific data that supports each postulate in natural selection

Individuals in a population vary in their traits 2. Most of this variation is heritable – passed on to offspring 3. More offspring are produced than can survive (due to limited resources such as food) 4. Individuals with advantageous traits are more likely to survive and reproduce Grant Finch Study: state and explain the specific data that supports each postulate in natural selection Medium Ground Finch Geospiza fortis
