Did eukaryotes arise from prokaryotes
WebNov 25, 2024 · Scientists generally think eukaryotes first came on the scene between 2.5 billion and 1.5 billion years ago, when evidence suggests that a bacterium took up residence inside a different kind of prokaryote, an archaeon, and became its mitochondrion. WebEukaryotes only appear in the fossil record later, and may have formed from endosymbiosis of multiple prokaryote ancestors. The oldest known fossil eukaryotes are about 1.7 billion years old. However, some genetic evidence suggests eukaryotes appeared as early as …
