It is common knowledge that humans have evolved, but the question is : Are they still evolving? If we consider our environment today then natural selection creates no need for new types of humans to evolve. At least not in the ways animals are forced by the factors in their environment to evolve.


Humans are still evolving though not at the rate that they were 100 years ago. This is due to environmental factors, now the strongest are not those who survive almost anyone can survive and reproduce nowadays thus taking the animalistic nature out of humans and taking some of natural selections work with it.

Background Knowledge

Humans have in fact evolved as shows by the chart at the right many species of humans have come and gone ihuman_evolution_chart.pngn the species seven million year lifespan. One of the most prominent changes that can be noticed with each species is the skull, containing the jawbones and the teeth structure.
In 1856 an odd skull was found that could not have belonged to any modern day human intrigued by what he saw Charles Darwin began researching human evolution and eventually published The Orgin Of Species. Thus the fever consumed the world and people began finding skulls all over the world. Eventually a consensus was made as the chart below shows. It is obvious that this is evidence for the evolution of humans because if you look at the chart then you can see that different types of humans evolved due to their different environments, currently it is assumed that humans have controlled their environment to the point where there is only one type of human in the whole world.

Modern Evolution

Human evolution accelerated enormously in the past 40,000 years until about 10,000 years ago. This was due to an increase in population size thus more mutations for natural selection to act upon. It was also due to the need for humans to adapt genetically to different climates and environments. However some theories say that the human mind stopped evolving about 10,000 years ago, or after the ice age. This would mean that we haven’t changed at all since the ice age, there is however much controversery over this belief. "The widespread assumption that human evolution has slowed down because it's easier to live and we've conquered nature is absolutely not true. We didn't conquer nature, we changed it in ways that created new selection pressures on us," said anthropologist Dr John Hawks, who has led a study to find out if we are still evolving today. In his experiment he selected two hundred and seventy individuals from four groups: Han Chinese, Japanese, Africa's Yoruba and northern Europeans.They found that at least 7% of human genes have undergone recent evolution. The changes include lighter skin and blue eyes in northern Europe and partial resistance to diseases such as malaria among some African populations, according to the study in Proceedings of the National Academy of Science . Recent in this case refers to about 5,000 years ago, so it disproves the ice age theory but still are we still evolving today? Lets take a leap in time and fast forward to the industrial revolution, ever since this time humans have gotten stronger and fitter, however evolution doesn’t always make this much sense because records show that any common Neanderthal woman could have easier beat the beefy California governor in an arm wrestling match.
Current findings by Yale Professor Framingham show that women are actually leading today’s natural selection, since generally
slightly short and plump women have children then in 2049 it has been predicted that the average child will be about 4 inches shorter and one kilogram heavier. While it cannot be predicted to the exact trait what our next evolutionary movement will contain it is very clear that humans are still very much subject to natural selection and that we are evolving.

Mutations are a way that we evolve, Darwin's principle dealt largely with natural selection, if something adapted to its environment adequately enough to reproduce then its traits will be passed down. Thus if a mutation occurs that is beneficial it will be passed down, mutations generally occur within the cell in the chromosomes it usually occurs in meiosis in the parent. Some chromosomal mutations that can occur are: deletions, inversions, and transcriptions.


As the model shows below humans are in fact still evolving, all animals are required to adapt to the environment and if they don't do this then they will be eliminated. The assumption that we are in control of our environnatrual_selection_model_.jpegment is not true, every animal has a certain environment or a habitat and as humans progress their environment changes and thus they have to evolve. The evidence that is presented is that we have evolved to an extreme degree in the past 5,000 years and ironically it has been in these years that we have maintained the most ' control' of our environment, thanks to the research done by Dr. Hawks he shows that about seven percent of humans have undergone recent evolution like blue eyes in Europe and sickle cell in Africa, these traits increased the ability of the organism to survive and thus were passed down. Since our environment is requiring less and less of humans physically in 2050 the average child should be slightly heavier and slightly shorter.


Evolution - Change through time, usually with reference to biological species, but may also refer to changes within cultural systems.
Natural selection - Evolutionary changes based on the different reproductive success of individuals within a species.
Fossil - The mineralized bone of an extinct animal. The remains of past life-forms.
Primate - Large-brained, mostly tree-dwelling mammals with three-dimensional color vision and grasping hands. Humans are primates.
Hominid - Modern human beings and our ancestors, generally defined as the primates who habitually walk erect. Technically, the members of the family Hominoidea.
