well its not something we can predict but here are eight possible ways we could evolve.
- As miscegenation becomes commonplace, humans will slowly begin to lose the distinguishing features of their ethnicity, and instead take on characteristics from many different parts of the world. There’s one obvious benefit to all this: “race” will no longer be an issue.
- There are two foreseeable causes for the gradual physical weakening of the human race. The first is our increasing reliance on technology – and in particular machinery – to do our dirty (but muscle-enhancing) work. The less each generation depends on physical strength, the more likely it is that the whole species will grow weaker.
- Human height has been growing rapidly for the last two centuries. Over the last 150 years alone, the average height of the species has increased by 10cm. It is believed that the main driving force behind this growth is the abundance of nutrition available to many of us. Famine has long been a curse for those aspiring to tallness – and in certain parts of the world, it has almost been eradicated.
The most obvious change to our jaws will be the disappearance of wisdom teeth, which serve no use to modern humans, and which already have low occurrence rates among some ethnic groups. But aside from this, we can also expect our teeth to grow smaller. Throughout the evolution of man, there has been a general trend towards smaller teeth.
- Humans may eventually reach a point where they can force evolution upon themselves through the use of technology. Whether this is literal self-improvement, via bionic organs for example, or through gene selection, which has prospective parents choose their child’s traits before birth, this is the most likely avenue human evolution will take in the near future. If permitted, gene selection in particular could quickly lead to a boom in so called “designer babies” – in which all defects and undesirable traits are removed. Should this become widespread, it could potentially force many negative human traits to extinction.
- Two schools of thought exist on the question of skull volume. The “small skull” camp, which enjoys the support of many scientists, argues that it is borderline impossible for humans to evolve with larger heads. Why is this? Well, anyone who has given birth knows that a child’s head is, to put it tactfully, rather large already. For this reason, many biologists believe that a larger head would make birth impossible – something the evolutionary process would phase out rather quickly, no doubt. A large head at birth is also more likely to hurt or kill the mother. With this in mind, it seems inevitable that head size will stay the same, or even decrease over time.
- Before humans walked upright, our toes were used for grappling – much like our hands. As we have come to rely less on climbing and more on walking, our toes have slowly shrunk to their current size. With our feet now woefully incapable of grasping even the smallest branches, evolution has taken steps to rid us of our smallest fifth toe.
All these are predictions we dont have any confirmations or proof to tell that this is what is going to happen. Happy answering.
