Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yachtold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

conflict resolution, sharing.

Humans engage in these types of behaviours all the time.

We've learned that it's a large part of the reason

we've succeeded as a species.

But a major question remains in science.

Are we the only species who do this?

As one of our closest relatives, chimpanzees have long been studied for signs of this.

Their genetic similarities could help us tease out the evolutionary trajectory of the desire to selflessly help others.

So far, research has provided mixed results on the question.

Studies of these animals in the wild and captivity

seem to come to different conclusions. Some studies show that chimps cooperatively hunt, share food
