Selective pressure is evolutionary pressure.The animals evolved due to selective pressure.Selective pressure caused the color to darken.

Examples of selective pressure include predators preying on specific traits, competition for resources driving evolution towards efficiency, and environmental changes favoring certain adaptations over others.
The separation of a population, selective pressure, and/or time.
When there is low gene flow When there is no selective pressure When there is a bottleneck
An example of something that is NOT a selective pressure would be random genetic drift. Selective pressures are environmental factors that influence an organism's ability to survive and reproduce, such as predation or climate changes. In contrast, random genetic drift involves chance fluctuations in allele frequencies in a population, which can occur regardless of an organism's fitness.
Selective pressure is crucial in the process of natural selection, as it drives the evolution of species by favoring individuals with advantageous traits that enhance their survival and reproduction in a specific environment. This pressure can arise from various factors, such as predators, climate changes, or availability of resources, shaping the genetic makeup of populations over time. Understanding selective pressure helps scientists predict how species might adapt to changing environments and informs conservation efforts. Ultimately, it underscores the dynamic interplay between organisms and their ecosystems.

Selective pressure from skin cancer can significantly impact reproductive success, particularly in populations with high UV exposure. Individuals with increased susceptibility to skin cancer may have reduced lifespan and reproductive opportunities, potentially leading to lower overall fitness. However, this pressure may be mitigated by behavioral adaptations, such as seeking shade or using sunscreen, which can reduce UV exposure and associated cancer risk. Ultimately, the strength of this selective pressure varies based on environmental factors and genetic predispositions in different populations.
