Inuit Adaptation To A High-Fat Diet

People do not really discuss this change in human evolution as much as they should. But many years ago, there was a big change for the Inuit people. Researchers found various, unique genetic mutations within the Inuit genome that allowed them to adapt to the severe cold much better than the average person. On top of this, they had a mutation that allowed them to have a high-fat diet.

The mutation allowed them to have a diet high in omega-4 fatty acids. While this often came with the side effect of being shorter, the Inuits still managed to live proper lives. Of course, this diet was high in seafood like fish and even seal or whale at times. The average human today could not handle such a diet without having some sort of health complication. But the Inuits, even those of today, have the ability to handle this diet.

How Doctors Avoid Getting Sick From Patients

It is stated that today, many kids are developing complications and sicknesses far more. However, the one community where this never happens is the Amish community. Why? Many people overprotect their children and do not allow them to get out and play in the dirt, with insects, and much more. However, the Amish community sees their children grow up around animals and agriculture, putting them outdoors and among potential viruses or infections often.

That slowly develops their immune system. A similar thing happens with doctors, and thanks to human evolution, healthcare workers often develop something known as Glutathione. It is an antioxidant and a protector of cells, which allows people like doctors and nurses to avoid getting sick from patients much easier. While things like their masks, uniforms, or classic coat also assist in protecting them from germs too, this antioxidant might be the prime reason they are so healthy.

The Extra Artery Humans Are Keeping

During the human evolution process, we have often dropped things from our genetic makeup or altered them. Sometimes, things might develop or show in the womb but won’t be present when a baby is born. It used to be that we had an extra vein running down our forearm that formed temporarily in the womb. Yet this always vanished before birth. Now, many people are still being born with this according to researchers at Flinders University and the University of Adelaide.

Essentially, we are now seeing people born with what is basically an extra channel of vascular tissue that flows from under the wrist. The researchers found that the consistent nature of people being born more and more with this goes back to the 18th century. Roughly 10% were born with it in the mid-1880s but that popped up to 30% during the 20th century! Our median artery works just fine in humans, so anything extra is not exactly useful. Some assume that having this could offer some sort of extra aid like more dexterity or strength. Rather, it makes one more prone to carpal tunnel syndrome than anything else.

Human Body Temperature Is Lowering

Human evolution can be a really cool thing. One would assume that we would not often see it in action among humans in such a major way. Since evolution is a slow process, we have to look at humans from an entire history, not just a few years. Yet the climate has only risen for the world. The massive rise is a direct result of human activity that is now out of control, along with the hole in our Ozone layer. As a result, humans are overheating.

Since the world also goes through a normal climate change, this has to happen along with what we are doing to it. Thus, making things happen quicker. This is thought to be why humans have dropped in temperature as a way to adapt. While the average temperature had been 98.6 Fahrenheit for most average, healthy humans. Today, we are seeing people more and more with temperatures of 97.3 to 97.9 degrees. As we know by climate, even one degree can be important.
