Endosymbiosis Idea a Proven Theory or Evolution Myth?

Abstract

The Endosymbiotic theory is a theory that explains the evolution of the mitochondria and chloroplast, which are organelles of eukaryotic cells. This theory originated at the end of the 1800s by Andreas Schimper, and later published by Lynn Margulis in the 1960’s in her book “Symbiosis in Cell Evolution.” According to this theory, these organelles originated as separate prokaryotic organisms, which were taken inside the cell as endosymbionts. Theory states that Mitochondria developed from proteobacteria (in particular, Rickettsiales or close relatives) and chloroplasts from cyanobacteria. There has been much debate about this theory and many questions have emerged because of it.. Is it truly possible for simple prokaryotes to evolve and also succeed as a complex eukaryote?
