Signs of evolution can easily be found in the human body. Vox recently put together this AMAZING video explaining how you can see evidence of evolution in your own body. From babies born with tails to why you get goosebumps.
I can’t recommend this enough to get a better understanding of how evolution has affected the human body.
Scientists at the University of Oklahoma are getting international attention for research into what’s in your gut. Cecil Lewis and his team at the Laboratories of Molecular Anthropology and Microbiome Research at OU studied what’s inside the guts of a group of Norman residents and compared it to the guts of a hunter-gatherer society in the Amazon.
They found that the population of gut microbes of the people in the Amazon and city-dwellers in Norman have some significant differences. For example, one microbe called Treponema was not found in the Norman population but was found in the tribe of hunter-gatherers. This is a bacteria that has been in human and primate guts for millions of years.
“In our study, we show that these lost bacteria are in fact multiple species that are likely capable of fermenting fiber and generating short chain fatty acids in the gut. Short chain fatty acids have anti-inflammatory properties. This raises an important question, could these lost Treponema be keystone species that explain the increased risk for autoimmunce disorders in industrialized people? This is what we hope to explore next,”says Lewis.
