descent with modification

Descent with modification refers to the process by which species evolve over time. It means that as organisms reproduce, their offspring inherit traits from their parents but may also exhibit minor variations. These modifications can result from mutations, genetic recombination, or environmental influences. Over many generations, these small changes can accumulate, leading to the development of new species or adaptations that enhance survival. Essentially, it explains how living things share a common ancestry while also adapting to their environments uniquely. This concept is fundamental to understanding evolution and the diversity of life on Earth.
