selection pressure

Selection pressure refers to the environmental factors that influence which individuals in a population are more likely to survive and reproduce. This can include things like predators, climate, food availability, and diseases. When certain traits give some individuals an advantage, these traits become more common in future generations. Essentially, selection pressure drives evolution by favoring characteristics that enhance survival and reproduction in a specific environment, leading to changes in the population over time. It’s a key concept in understanding how species adapt to their surroundings.
