Strength changes While there is no proof that modern humans have become physically weaker than past generations of humans, inferences from such things as bone robusticity and long bone cortical thickness can be made as a representation of physical strength.
According to research, we're losing substantial bone strength – with up to 20% less mass than our ancestors had [4]. This trend toward less bone mass is one of the most conclusive signs that we are becoming weaker as a species.
Human Muscles Evolved Into Weakness, In Order to Boost Our Brains. Much like our brains, human muscles have evolved several times more rapidly than primate muscles, according to a new study — but that process has made us weaker over time in a process, while brains become more advanced.
Humans are growing weaker, more disease prone, and just might be developing some manners, according to a new study that asserts humans are still evolving according to Charles Darwin's natural selection theory.
Technology could be making us slower and weaker, according to new research. Cambridge University researchers say that after looking at leg bones of humans dating back to the beginning of agriculture in Central Europe, our bones show a decline in “mobility and loading,” especially among males.
If we were to exert our muscles to or beyond their absolute maximum, we could tear muscle tissue, ligaments, tendons and break bones, leaving us in dire straits. "Our brains are always trying to make sure we don't get pushed too far to where we actually damage something," says Zehr.
Technology can't replace the human aspect of communication and leadership. As humans, we have an innate capability to understand how another person is feeling, and how it affects them in their day-to-day life. We know how customers really feel through interpretation, and we have compassion for them.
Genetic studies have demonstrated that humans are still evolving.
By virtue of being the same species, all humans share 99% of their genome, which means that all humans are 99% genetically similar. Our bodies are made up of 3 billion genetic building blocks, or base pairs. Of those 3 billion base pairs, only a tiny amount are unique to us.
The last “sympatric” humans we know of were Neanderthals, who became extinct only about 30,000 years ago. Since stable separation of parts of the species is the key factor for the formation of new species, we can say that a new split of our species is impossible under current circumstances.
And especially among males, the reduction in strength compared to 30 years ago was striking. The average 20-to-34-year-old today, for instance, was able to apply 98 pounds of force when gripping something with his right hand. In 1985, the average man could squeeze with 117 pounds of force. Now, there is a caveat here.
Our ancestors, who had to hunt and gather their food before the invention of agriculture, were more physically active than we are. Their bones were much stronger, too. A new study shows that human skeletons today are much lighter and more fragile than those of our ancient ancestors.
Notes. The human limit of strength is considered to be 800-1,000 lbs (about 360 to 500 kg) over-head, and 1,100-1,500 lbs (about 500 to 680 kg) bench press.
Human evolution relies on the differences in our genes and in our ability to pass on these genetic differences (ie our breeding capabilities). Over time, the population should change as these differences become more apparent. If the genetic changes are great enough, a new species will arise.
In the real world, extraordinary strength can occur via science. A person can become stronger, tougher, and more physically powerful than would seem humanly possible when using enhancements such as doping, substances and training.
Could we mate with other animals today? Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
Chimpanzees
We share 99 percent of our DNA with chimpanzees, so it comes as no surprise that countless hours of research have been dedicated to understanding the intelligence and behavior of our sister species. This research has firmly established that chimps are one of the most intelligent species on earth.
The short answer is no. An individual of one species cannot, during its lifetime, turn into another species.
But even if that common ancestor still existed, the fact that evolution is the result of both random mutation and a process of natural selection imposed by environmental conditions, means it's highly unlikely that it would ever retrace its steps in quite the same way.
It has been argued that human evolution has stopped because humans now adapt to their environment via cultural evolution and not biological evolution. However, all organisms adapt to their environment, and humans are no exception.
We will likely live longer and become taller, as well as more lightly built. We'll probably be less aggressive and more agreeable, but have smaller brains. A bit like a golden retriever, we'll be friendly and jolly, but maybe not that interesting. At least, that's one possible future.
Empathy and Communication Skills
Another advantage that humans have is their capacity for empathy and their effective communication skills. Humans are able to relate to and understand each other in ways that machines are unlikely to achieve anytime soon, if at all.
To say our society would go into a tailspin during a day without technology is an understatement. Without technology, society would regress by at least 50 years. Imagining what it would be like to survive a day without technology makes the IT skills gap difficult to fathom.
