It is a discovery that’s 'one for the textbooks.'

A team of scientists have detected a sign of a major life event that has likely not occurred for at least one billion years. They’ve observed primary endosymbiosis–two lifeforms merging into one organism. This incredibly rare event occurred between a type of abundant marine algae and a bacterium was observed in a lab setting. For perspective, plants first began to dot our planet the last time this happened.
