What is differential reproduction?

Differential reproduction means that some individuals in a population are more likely to reproduce and pass their genes to the next generation than others. This can happen due to various factors such as genetic traits, environmental conditions, or behavior. Over time, these differences in reproduction can lead to changes in the frequency of certain traits in a population, which is the basis of evolution by natural selection. The individuals who are more successful at reproducing are said to have a higher fitness, and their genes become more prevalent in the gene pool. Differential reproduction is essential for the process of natural selection to occur, as it leads to the gradual accumulation of beneficial traits and the elimination of less advantageous ones.
