Homologous structure is when two organisms have the same structure but the structures have different functions.
A bat and humans have similar limb structure but they preform different functions. Our hands help us grab things while a bats hands will help them fly and hang upside to sleep.
We both have hands!!
This structure is shown through many species so due to that it supports common ancestors.
We come from common ancestors.
However unlike homologous analogous structure have diffrent structure but the organisms brefore the same function.
We can fly!!!!!!
An example of this would a butterfly and a bird. They both have the ability to fly but their structures that allow them to do that are diffrent.
I flutter because i don't have bones.
I fly using the bones in my wings.
This structure is different than homologous because it does not shoe common ancestry. The species this structure relates to they are too different to have decedent from the same ancestor.
We are not related.
