Microbiome of Our Ancestors Highlight Human Evolution History, Scientists Claim

We, humans, are one of the most developed and successfully living species Earth. We have managed to live in extreme conditions like waterless deserts and frozen regions. Even more, humans have developed various tools that assist in survival and even exceed the limits of life science. The creativity and adaptability of humans functions as superpowers for humans. But the origins of that strength may emerge in surprising regions, maybe the gut or the armpit sweat of our closest residing ancestors. Usually, we surmise the human microbiome as the thriving group of bacteria that reside in our gut. Experts say these bacterial populations can affect many aspects ranging from a person’s mood to mental stability. This community covers above and beyond the gut, including the skin, stomach, and the sweat glands of our armpit.

In a new study, researchers claim this wide-range community of microorganisms sheds light on human evolution. Aylssa Crittenden, an anthropologist from the University of Nevada, Las Vegas, is a correspondent author of the trial. He said the sociality of humans is a trademark of human advancement. Before this, researchers have disregarded the effect that the microbiome could impose on some particular questions. She notes social behavior is one of the defining features of homo sapiens. Besides, the research pinpoints the deep relationship between the microbiome and social behavior of humans.

The latest study offers an exciting overview of three features of humankind’s origin story. Researchers say the microbiome plays a crucial role in their findings. The team has focused on the microbiome advantage, armpit ecology, and extending the microbiome. Even more, they have surmised what type of microbiomes of our closest surviving relatives might have been like and their transformation. The researchers have outlined the finding in a paper released in Frontiers in Ecology and Evolution on Wednesday. Still, it requires more effort to verify the theory.
