Gene trees provide important Endosymbiotic theory explains why organelles resemble free-living bacteria. • Gene trees are well-suited to testing endosymbiotic theory, but not to replacing it. • Testing endosymbiotic theory requires that we keep LGT and pangenomes in mind. • The SELMA translocon is an important marker to trace secondary endosymbioses. • The theory of how mitochondria, chloroplasts and other membrane-bound organelles in eukaryotic cell likely arose from a symbiosis between aerobic prokaryotes and host anaerobic eukaryotic ancestors.

Endosymbiotic Theory As scientists were making progress toward understanding the role of cells in plant and animal tissues, others were examining the structures within the cells themselves. In 1831, Scottish botanist Robert Brown (1773–1858) was the first to describe observations of … Explore the endosymbiotic theory with the Amoeba Sisters!
