Genetics The Origin of Species?. In this book Darwin theorized that populations evolve over the years through a process called natural selection. Darwin realized that in a Humans essay, more individuals were born than could possibly survive, he also recognized that the individuals that survived and reproduced were the ones with some sort of competitive advantage over rival animals, therefore they were more likely to pass their useful traits down to their offspring Darwin, We will write a custom essay sample on Are Humans Still Evolving?
There are countless amounts of evidence that suggest that humans owe their existence to evolution, however, many people are skeptical as to whether or not it is still occurring, and whether or not it is happening in the same way. Some scientists hold that the human race has reached?
Alternatively, some experts believe that humans are evolving faster than ever Sample,and others believe it is still happening, just on different terms. There has not been any deciding evidence as to whether or not humans are still evolving, however, saying it isn?
Gene mutations happen at random so saying that humans will never undergo any more evolutionary changes seems very unlikely Douglas, Many scientists and evolutionists believe that the complexion of modern society is changing the means by which natural selection and, consequentially, evolution is occurring.
The evolutionary trait of an advanced brain is what defines us as humans; ironically that same brain is what is allowing us to change the rules of evolution. As a result of a number of medical advancements, doctors are able to sustain life that would not have lasted back in Darwin?
This means that humans with genetic advantages are not the only ones to survive Nasrallah, When considering how evolution might be happening, experts say the human species may be?
Upcoming technological advancements may also play a big role in changing the way in which evolution functions. If genetic engineering becomes common, humans will be able to choose certain genes and get rid of others; the future of evolution will be dependent on which genetic traits parents will choose for their children.
This would have huge implications; humans would essentially have evolution in their hands Adams, It seems that in modern society, humans have more of a say in natural selection than nature and the environment does.
Additionally, survival of the fittest has been taken out of the equation with the? Nasrallah, replacing it. On the other hand, some scientists like to believe that evolution was halted between fifty thousand and a hundred thousand years ago, before the races diverged Douglas, Geneticist Steve Jones theorizes that evolution has come to a halt as a result of societal changes on earth McKie, He says that natural selection, mutation, and random change were the three things that drove evolution, and he believes that these factors are no longer present in the modern, western society.
He further argues that the likelihood of mutations in genes is declining because of a generally younger age for fathers; he says fathers over the age of 35 are more likely to pass on mutations.
This is because cell divisions in males increase with age, and increasing the number of cell divisions increases the chance for an error or a mutation Belluz, Natural selection is also not as prevalent in modern society, years ago almost half the children died before twenty, whereas nowadays most people reach adulthood regardless of their genetics Douglas, The final factor that Jones believed was responsible for the slowing down of evolution is the decreasing of random change in human genes.
According to the rules of the animal kingdom, the human population should be ten thousand times smaller than it actually is Belluz, Small populations are much more likely to undergo random evolution than large populations because genes can be accidentally lost.
Furthermore, human races are now being constantly mixed, which makes the likelihood of losing any genes even less McKie, Although all of these factors contribute to a change in the way evolution happens, it seems very farfetched that evolution can ever truly be stopped.
In an alternate view, others are convinced that evolution is now happening faster than ever because of the speed at which society is changing. According to a study done at the University of Wisconsin: This increase in the rate of evolution appears to be because of rapid growth in population Shute,new mutations are being spread around faster than ever before.Human Nature - Are humans naturally good or evil?
