A simple and well-known example is that of the evolution of the human being. Scientists, based on genetic studies and morphology, among others, believe that the current Homo sapiens descends from sipery ancestors and therefore shares many characteristics with chimpanzees and other primates.

What is evolution
Evolution is more complex than you think. It is not simply the adaptations that an organism experiences according to its environment, but combines several mechanisms that make possible the different characteristics between the millions of species on the planet.
All changes have occurred through genetic inheritance, which means individuals transmit adaptive genetic changes to their descendants and, at some point, modifications become common in a population of living beings.
Modern science indicates that a common ancestor gave rise to the enormous diversity of living beings that exist, so, although it seems unbelievable, all organisms are related. It is believed that about 3.5 billion years ago the first procariota bacteria appeared and about 2 billion years ago the first eukaryote cells were created with real organelles.
The first living things made up of more than one cell could have originated about 1 billion years ago. The Proterozoic era saw the birth of the first fish and the Paleozoica to the plants and the fungi. Mammals have existed since the Mesozoic era. Over time the organisms became more complex.
