Greek philosopher Heraclitus once said, “There is nothing permanent except change.” No paradox has spoken more truth than this. For thousands of years, the earth has been evolving, and so are we. But how are we going to evolve in the future? Here are a few ideas:
- Smaller Brains
Compared to other species, we consider ourselves as smart. But for the past thousands of years, it has been discovered that human brains are actually growing smaller. One theory is that we are becoming more efficient, having all the information spoon-fed to us, making us need less memory space.
As disturbing as this sounds, there is a theory that humans will someday grow beaks. According to Dr. Fraser from the University of Sheffield, there are evolutionary similarities between human teeth and the beak currently sported by the puffer fish. Apparently, puffer fish used to have individual teeth but later fused together into a hard single beak. Dr. Fraser, therefore, predicts that humans will end up in the same boat.
- Fewer Toes
Pinky toes are useless. At least that’s what some people think. When humans crawled, climbed, and shuffled about, the pinky toe was vital in helping us move around. But as we have evolved into a more upright walk, it has spent millions of years slowly shrinking. Other species like cows, pigs, horses, and even dogs, have discarded the use of pinky toes from their anatomy. Scientists also predict that in five hundred thousand years, humans will do the same.
- Weaker Immune System
As medical science continues to improve, humans have become more and more dependent on pills and medicine. This has caused our immune systems to slack off and according to scientists, might cause our immune systems to grow significantly weaker in the following years. If this happens, this poses a threat to the existence of humanity as we may be wiped out by a strong and unexpected pathogen.
