Lynn Margulis was born in Chicago, Illinois on March 5, 1938. This was around the time World War 2 was getting started. She graduated from the University of Chicago in 1957, at which point she was only 19 years old. After a few months she married Carl Sagan. Their marriage lasted about 7 years, after which they divorced. She had a son with him, named Dorion Sagan, who helped her write some of her books. During her marriage, Lynn Margulis had received a master’s degree from the University of Wisconsin in 1960. Right after the marriage, Lynn received a Ph.D from Berkeley in genetics. For her research, she received the 1999 National Medal of Science. In her lifespan, she received a total of 8 awards for her research. She died in Amherst, Massachusetts,

Endosymbiosis is the theory of prokaryotic cells producing mitochondria and chloroplasts in eukaryotic cells. This theory does have evidence. Both chloroplasts and mitochondria contain DNA and are able to reproduce, not paying attention to the cell’s reproduction. A chloroplast’s DNA does not appear to be like a plant cell’s DNA. The chloroplasts have the ability to absorb energy with photosynthesis, while the nucleus of the cell cannot. The way a eukaryotic cell would contain a prokaryotic cell is through either an ‘invasion’, being eaten, but not able to be digested, or an internal parasite. This process is called symbiogenesis, where two organisms become one. This also shows endosymbiosis due to the fact that the cells help each other live. Part of this theory stated that the prokaryotic cells were specialized cells, which allowed the prokaryotic cells to function like chloroplasts and mitochondria. The combination of the specialized prokaryotic and eukaryotic cells was thought to have happened two billion years ago. Ribosomes with mitochondria have DNA that does not repeat, and is extremely complex. It's thought that endosymbiosis has led rise to new species as well as cells. Many evolutionary biologists don't think that this impacted eukaryotic cells much, and think there is little evidence apart from mitochondria and chloroplasts, though many ecologists think
