In the context of evolution, what does "descent" refer to?

In the context of evolution, "descent" refers to the lineage from ancestors to offspring. This concept is central to the theory of evolution, as it emphasizes how species evolve over time through genetic inheritance. Each generation inherits traits from its ancestors, which can affect their survival and reproduction. This process leads to the gradual change of species, where characteristics may adapt or shift over generations, ultimately resulting in the diversity of life we see today.

The idea of descent connects closely with the principle of common ancestry, illustrating that all living organisms share a heritage that traces back through time. This hereditary lineage is fundamental to the understanding of how traits are passed down and how evolution operates within populations, guiding the adaptive changes that species undergo in response to their environments.
