Human has not stopped evolving. Assuming that civilization continues along the same path as today major changes will be expected over the next few years. Since civilization hasn’t been around for long we can expect extraordinarily changes as years draw by. Here some major changes we expect in human evolution.
There are two main foreseeable causes of human gradual physical weakness which are; Over reliance on technology most especially on machine to do our muscle enhancing work. This makes the whole species weaker since they do not depend on physical strength for body muscle growth. If we were to relocate to space the second cause of muscle atrophy is much relevant. Here physical strength is less necessary for day to day activities but it doesn’t mean we spend too long as explorers since we eventually lose most of our body muscle mass. The future generation should consider this to prevent finding themselves confined to wheelchairs.
Smaller/larger scull volume
Scientists argue that it is impossible for human to evolve with larger heads. The ‘small scull’ gets all the support from biologists who believe that a larger head will make birth impossible. A larger head at birth is most likely to kill or hurt the mother and with it seems the head size will stay the same or decrease over time. With advanced technology caesarean section has provided more opportunities for survival of big headed children which is heart thrilling for the mothers affected. Many may think that C-section is safer than natural birth but its dependence would be dangerous for human.
Soon human will reach a point where they can force evolution on themselves through technology. A good example of this is through gene selection where prospective parents choose their child’s trait before birth. This is the avenue of human evolution will take in near future leading to a boom of what is known as “designer baby” in which all undesirable traits are removed.
As long as multiculturalism continues being the essence of modern society humans are expected to evolve into a single ethnic group. Humans will start slowly start losing the main distinguishing features of their ethnicity and take on characteristics from different cultures in the world. This is a benefit since race will no longer be a problem.
For the last two centuries human height has been growing rapidly which is believed is caused by abundance of nutrition. The more a person’s eats the more energy he/she has to grow. Eating will make species to grow taller whether the sky is our limit or not. Only evolution can tell the limit of tallness.
Technology has greatly affected how our memory works. Our brain can only remember where the information is stored but not the content. Technology is advancing each day thus our brain adapts to maximize properly at the detriment of our memory.
Weakened immune system
Human immune system is growing weaker due to relying on medication for survival. It is foreseeable that soon humans will evolve to the point where hormones no longer organically created within the body. Our body needs a powerful immune system to fight diseases and self-dependency. Use of medication will only make most of our internal functions obsolete.
These are the recent levels of evolution which will be taking place in the next few years to come. Evolution is advancing so fast that many changes are not easily noticed. With time humans will have many more variations in traits as years goes by. Evolution from apes to human to more advanced creatures in future with better living environs mixed cultures and level of intelligence.
