Lynn Margulis was an influential biologist renowned for her groundbreaking theories in evolutionary biology, particularly her work on the endosymbiotic theory. This theory proposed that complex cells, known as eukaryotes, originated through a symbiotic relationship between different species of simpler cells. Margulis emphasized the importance of cooperation among microorganisms, challenging traditional views that focused solely on competition in evolution. Her work often intersected with the fields of microbiology, genetics, and environmental science. Margulis was...
