Adaptive Evolution: This refers to changes in populations due to beneficial mutations that increase survival and reproductive success. It's like how software updates help your phone adapt better to your needs over time.
Natural Selection: The process where organisms with favorable traits (like those caused by beneficial mutations) are more likely to survive and reproduce. It’s akin to users preferring smartphones with better features resulting from updates.
Genetic Variation: Differences within species' genetic material that may lead to evolution through natural selection – much like different versions of smartphones having various features.
