WebThe process of reproduction, while mostly accurate, is imperfect. When cells divide, they have to replicate their DNA. Although DNA replication is highly accurate, it still makes about 1 mistake in 10 million nucleotides. Over generations, the population will contain lots of heritable variation. WebJan 1, 2024 · Differential selection refers to a class of selective pressures that disfavor (or favor) some members of a population over others. The mechanics of differential selection may differ with any given level of analysis. Variation in fitness consists of two interrelated concepts: variation and fitness.Variation is a descriptor for differences that exist within a …

Each species has diversity within it, not all organisms are exactly the same. Therefore, not all of them have the best characteristics to survive in a given environment.
