Question

In the late 1800s, a biologist studying animal embryos coined the phrase "ontogeny recapitulates phylogeny," meaning that the physical development of an animal embryo (ontogeny) seemed to retrace the changing form of the species during its evolutionary history (phylogeny). Why would embryonic development retrace evolutionary steps?

Step 1

Evolution occurs through the gradual accumulation of small changes in an organism's genetic material over time. These changes can lead to new traits and adaptations that help the organism survive and reproduce in its environment. Show more…
