On average, 11 percent of DNA is inherited from a common ancestor around 5 generations back.
what is Similar structures that related species have inherited from a common ancestor
A trait shared with a common ancestor is called an inherited or ancestral trait.
An ancestral trait is a trait that is shared by a group of organisms and their common ancestor. It is a characteristic that has been inherited from a common ancestor and has been passed down through generations without change.
If two people are each 20 generations from their common ancestor, they are 18th cousins. If they are not both 20 generations from the common ancestor, then they may be 17th cousins once removed or 16th cousins twice removed, etc., up to 1st cousins 17 times removed - depending on where each is in the descendency tree in relation to the common ancestor
Homoplasy refers to similarities in traits between different species that are not inherited from a common ancestor, while homologous structures are traits that are inherited from a common ancestor and have similar functions.

The pentadactyl limb structure, found in mammals, birds, reptiles, and amphibians, is inherited from a common ancestor. Despite modifications for different functions, such as wings in birds and flippers in whales, the underlying bone structure remains similar.
