Scientists Recreate the Conditions That Sparked Complex Life

One cell might slip inside another and make itself comfortable.

If the conditions are just right, it might stay and be welcomed.

This phenomenon of one cell living inside another, called endosymbiosis, has fueled the evolution of complex life.

Scientists have struggled to understand how they happen.

Researchers used a microscope to inject bacteria into a fungus's cell wall.

The bacteria wiggled their way into the fungal spores to hitchhike to the next generation.

As the two organisms reproduce together in successive generations, each will adapt to the other until they find endosymbiotic balance.

Bacteria-fungus pairing is only one example of a process that may have a number of mechanisms or conditions.

By inducing endosymbiosis, researchers could potentially engineer plants to metabolize pollutants or manufacture medicines.

“Many new features could be brought together in a symbiotic system by doing this and making them evolve together,” Laila Partida Martínez said.
