Now, Stäubert and her colleagues have found one way that lactic acid bacteria interact with our bodies. Initially the researchers were investigating proteins on the surface of cells called hydroxycarboxylic acid (HCA) receptors. Most animals have only two types of this receptor but humans and great apes have three. The researchers discovered that a metabolite produced by lactic acid bacteria, D-phenyllactic acid, binds strongly to the third HCA receptor, signalling the immune system their presence.Good so far. Not a solution yet, but a path that could lead to better understanding and more precise use of lactobacteria.
The researchers propose that the third HCA receptor arose in a common ancestor of humans and great apes, and enabled them to consume foods that are starting to decay, such as fruits picked up from the ground.Here's the ad for good old Savannah Sabertooth. First, it's simply unnecessary. Descriptions based on "evolution" are ALWAYS unnecessary. All problems can be understood fully, and all solutions can be implemented fully, without TOUCHING the whole concept of "evolution". Second, EVERY mammal eats fermented fruit, and many mammals enjoy it. So the ability to eat fermented fruit is NOT specific to humans and chimps. If research focuses on this distinction, it will waste time and effort.
