A New Era in Evolution: Two Lifeforms Merge to Form a Single Organism through Endosymbiosis

In a unique turn of events, two lifeforms have merged to form a single organism through the process of primary endosymbiosis. This rare occurrence has only been observed twice in Earth’s history, and it has significant implications for evolution and agriculture.

An international team of scientists recently witnessed this evolutionary event between an ocean-dwelling algae species and a bacterium. In this process, the algae engulfed the bacterium to form an internal organelle, offering valuable insights into how complex life forms can develop.

Tyler Coale, a postdoctoral researcher at the University of California, Santa Cruz, led one of the studies that uncovered this phenomenon. He emphasized the significance of this event in the history of complex life on Earth and the potential for engineering similar organelles into crop plants to improve nitrogen fixation.

The research papers detailing these findings were published in esteemed scientific journals Science and Cell. The collaborative efforts of scientists from various institutions such as MIT, UC Santa Cruz, Lawrence Berkeley National Laboratory, and universities in Japan and Spain were instrumental in unraveling this groundbreaking discovery.
