Embryology and Evolution
When scientists study embryos, which are the early stages of development in animals, they notice something fascinating: many different species look very similar at this stage. For example, human embryos, chicken embryos, and fish embryos all share features like tails and gill-like structures.
This similarity suggests that these animals may have come from a common ancestor. Even though they grow up to be very different—humans, chickens, and fish—they started off looking quite alike. This is because their early development is influenced by similar genetic instructions.
As these animals grow, they adapt to their environments, leading to the differences we see as adults. The fact that many species share similar embryonic stages supports the idea that they evolved from the same distant relatives.
