Not Just Because - Biology

"Survival of the fittest" doesn't mean the strongest or fastest always win — it means the living things whose traits best fit their environment are more likely to survive and have offspring. Over many generations, small inherited differences can add up to big changes in a population, from the color of a moth's wings to the shape of a finch's beak.

"Survival of the fittest" doesn't mean the strongest or fastest always win — it means the living things whose traits best fit their environment are more likely to survive and have offspring. Over many generations, small inherited differences can add up to big changes in a population, from the color of a moth's wings to the shape of a finch's beak. The episode traces how natural selection works step by step, why evolution happens to populations rather than individuals, and what scientists still wonder about the process.
