Explanation:
Evolution is a slow natural process occurring in living organisms which explains the formation of the diversity of organisms on Earth. In simple terms, evolution explains how life survived on Earth after the origin of life but it cannot explain the origin of life. However, modern evolutionary biologists are now trying to decode the origin of life through evolutionary evidence and support that earlier form of life originated in the large oceans around 3.5 billion years ago. These organisms are simple living unicellular organisms which later evolved into the eukaryotic organisms.
The difference is found in the DNA chromosome of the male and females.
The males have XY chromosomes at the last while the females have XX, these chromosome labels are important to signify deviancy and disparities among the morphology and the later structure of the female and male functions.
