For those interested but new to role of endosymbiosis in evolution, it's useful to keep in mind that there's strong evidence of an endosymbiotic origin of chloroplasts, another major event in the history of life. Here's a recent review article that highlights some of the key evidence and outstanding questions: Sibbald SJ, Archibald JM. Genomic Insights into Plastid Evolution. Genome Biol Evol. 2020 Jul 1;12(7):978-990. doi: 10.1093/gbe/evaa096. PMID: 32402068; PMCID: PMC7348690.
