Webh) A lot of basic research in molecular and cell biology is performed on yeast (a fungus), and the results are typically applicable to mammalian cells. Bacteria such as E. coli are cheaper and easier to culture that yeast, and their biology is extremely well known (more is known about E. coli than any other organism in the world). Yet, yeast is a much better model … WebStudies of mitochondrial DNA (mtDNA) suggest that the common ancestor of all modern humans lived approximately 200,000 years ago, implying that modern humans (Homo sapiens) arose in Africa (the out-of-Africa hypothesis). page 497 The mtDNA out-of-Africa pattern is supported by Y chromosome analysis, which also shows a recent African origin …
