Natural selection is the process by which populations of living organisms adapt and change.
Variation means that some individuals have traits better suited to their environment than others. These individuals are more likely to survive, reproduce, and PASS THESE TRAITS TO THEIR OFFSPRING.
Through natural selection, favorable traits are transmitted (passed) through generations.
Which of the following are NOT examples of natural selection? (MARK ALL THAT APPLY)
(1 point)
1. A bird population with different beak sizes surviving better depending on the availability of different types of food sources.
2. A bacteria population developing resistance to antibiotics over time due to repeated exposure.
3. A polar bear population growing in numbers due to increased protection and conservation efforts.
4. A flower population producing bright colors to attract pollinators for reproduction.
The examples that are NOT examples of natural selection are:
3. A polar bear population growing in numbers due to increased protection and conservation efforts.
4. A flower population producing bright colors to attract pollinators for reproduction.
These examples do not involve the process of individuals with favorable traits being more likely to survive and reproduce, and therefore do not illustrate natural selection.

The examples that are NOT examples of natural selection are:
1. Dyeing your hair green - This is a deliberate choice made by an individual and is not a trait passed down through generations.
2. Increase in muscle mass due to diet and exercise - This is also a result of individual choice and behavior, not a genetic trait passed down through generations.
The examples of pesticide-resistant insects and giraffes' long necks are examples of natural selection, as they involve traits that provide an advantage in the organisms' environment, leading to their increased survival and reproduction.
