![]() ![]() Homologous organs are the organs that are structurally similar to each other but perform different functions. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations. Opposite of analogous organs are homologous organs. If any two structures or organs perform similar functions but are structurally different, they are analogous structures or analogous organs. Predator-prey "arms race"Predators evolve better ways to catch prey. Analogous organs are also termed analogues. Evolutionary branching trees can show how adaptation leads to new species over time.Like a family tree, it shows how organisms evolved from common ancestors that may no longer be alive on earth today.Analyzing the embryos of animals shows that the more closely related the animals are, the more alike their embryos are during development. W hile the forelimbs slowly evolved into flippers, the hind limbs Slowly disappeared and all that is left is a few tiny bones.The birds’ beaks are shaped differently so they can occupy different niches in the ecosystem. In order to adapt to various environmental conditions, the two groups develop into distinct species due to differences in the demands driven by the environmental circumstances.ĭarwin’s finches show a path towards divergent evolution. ![]() a group from a specific population develops into a new species.In different parts of the world, ant eating animals developed long snouts and powerful digging paws. Organisms that are NOT related evolve similar traits as a result of evolving to fit into similar environments or ecological niches. ![]() They have the same function and shape, but are made differently.Īnalagous structures help to show Convergent Evolution The wings of the bat, butterfly, and bird are made of different coverings, and insects do not have internal bones. ![]() The bones of the bat, mouse, and human are homologous.
