How have human beings ever evolved?

Answer 1

Yes, humans are still evolving and have not met the hardy-weinberg equilibrium. Although, I do believe our rate of evolution has been slowed down. The hardy-weinberg theorem states that allele frequencies will not chance if there is a large population, mating opportunities are equal, no mutations occur, no migration occurs, and no natural selection occurs.

We certainly do have a large population (exception to certain isolated tribes that have not been influenced). This has slowed evolution because chance effect of genetic is nullified.

It is arguable to say mating opportunities are not always equal; we have a hierarchy in society where the rich are clearly separated from the average and poor. We all have a tendency to mate with each other. Also, our ability to reason (which seperates us from all other species) has allowed us to make a much more in depth analysis into what behavioral and physical traits we are attracted to in our mates (does not strike me as much different then sexual dimorphism). This implies sexual selection, which is a form of natural selection.

Think of all the locations where mutations occur (during replication, transcription, and translation), it is very unreasonable to think that in the entire human population no type of mutation ever occurs. It also has been proven that a mutation occurs, in a large population, in one in every gamete. Therefore, microevolution is still occurring.

The human race is obviously always migrating to different countries, and therefore are under different environmental pressures. A problem however is that we have gotten extremely good at altering our environment to our standards rather then adapting. Furthermore, it has been proven that a gene on chromosome 12 in Africans has 21 different variations (this is one amongst many differences in allele frequencies between different races). Therefore, if a North American, who only has 3 variations, mates with an African, then the allele frequency has changed and again the hardy-weinberg conditions are not met.

Answer 2

Humans were created by God so they do not evolve. Look in the book of Genesis. Kjv version.S's

Well are necks will get longer, our eyes and ears will get smaller and our noses will grow longer. Our arms will grow shorter but our legs will grow longer. and will might not grow any hair

Answer 3

Certainly not. Evolution doesn't simply stop. Organisms are always evolving to compensate for some environmental factor. An organism that stops evolving is one that goes extinct. However, evolution isn't an instant change. It happens very, very gradually (except in microorganisms). Homo sapiens hasn't been around all that long, and despite this, there are still noticeable evolutions amidst the species, to keep up with the accelerating pace of modern society. There have been several predictions about the circumstances surrounding the next major evolutionary step for the human race, an evolution past Homo sapiens.

Answer 4

That's a good question. Homo Sapiens is the paradox of evolution, that is process of natural selection through the survival of the fittest, of which the human being is claimed as it's proudest achievement, the glory and the crown, and yet one of the most unfit to survive, the weakest and most frail organisms on the face of the planet, that has reached the very pinnacle of nature, leaving the competition in the dust, and is now standing on the threshold of unlocking the deepest mysteries of the universe. Maybe one day soon we will be able to understand who we really are, and how we came to be who we are.

Answer 5

Evolution is an ongoing process. However the common concept that we will "improve" is not correct as the general concept is that improve means more beautiful, stronger etc. How we evolve depends on the environmental pressures we face. As an example mankind evolved in the last 10,000 years to be able to digest cow's milk/ This was probably the result of the domestication of the cow and the availability of cows milk during hard times. people who couldn't use this food died off. Other evolutionary traits of recent times are blue eyes and the ability to see blue. The usefulness of these traits and their cause is not known. AT the present time both humans and the ebola virus are evolving - us to withstand it and ebola to infect us better.

Answer 6

Human beings have evolved through a process called natural selection, where advantageous traits are passed down through generations. Over time, mutations and genetic diversity have contributed to our development, allowing us to adapt to changing environments and circumstances. Additionally, factors like migration, interbreeding, and environmental pressures have also played a role in shaping human evolution.
