Key Concepts Covered

➡️ Natural selection – The process by which certain traits become more common in a population due to differential survival and reproduction.
➡️ Genetic variation – Differences in traits caused by genetic differences within a population that natural selection acts upon.
➡️ Adaptation – Traits that improve survival and reproductive success in specific environments.
➡️ Allele frequency changes – How traits become more or less common over generations due to selective pressures.
➡️ Environmental influence – The role of changing conditions like droughts or antibiotics in shaping evolutionary outcomes.
