In evolution: Ethological (behavioral) isolation. Sexual attraction between males and females of a given species may be weak or absent. In most animal species, members of the two sexes must first search for each other and come together.

What is meant by ethological isolation?

ethological isolation The failure of individuals of species with recent common ancestry (i.e. related species or semispecies) to produce hybrid offspring because differences in their behaviour prevent successful mating taking place.

What is ethological isolation with example?

It is sometimes called ethological isolation. This happens when two populations of the same species develop some difference in behavior. A common example is mating rituals. Due to differences in their behaviors, the populations may be unable to recognize each other as potential mates.
