| The apicoplast is a newly identified residual plastid acquired by secondary endosymbiosis that has attracted attention for its evolutionary novelty and its potential as a drug target. Endosymbiosis fell out of fashion for many decades, but in the early 1970s, Lynn Margulis of the University of Massachusetts in Amherst breathed new life into the idea. To explain these findings, scientists devised the serial endosymbiosis theory, which essentially holds that primitive microbes evolved into more complex ones by swallowing other microbes and putting them to work as organelles. |
