👉 "Nonselection" is a concept in evolutionary biology that refers to situations where individuals are not selected for by their environment or the availability of resources. This can occur due to genetic traits, environmental factors, or both. In other words, individuals may be unable to reproduce because they lack the necessary genetic material or resources. Nonselection can be beneficial if it allows a population to adapt and evolve over time, but it can also lead to extinction if it prevents reproduction.
