If the evolution theory is true...... are we human still evolving? please give example?

Answer 1

Yes - very slowly.

There's debate on the use of the appendix - some saying it helps with immune functions - others saying its a dying part of the large intestine.

Another example would be body hair in general - specifically on fingers/toes. A final example would be the 'pinky' toe - there's not much use to it (less possibly balance).

Finally, researchers are discussing whether the male chromosome will survive.

Answer 2

Whether or not any particular *theory* of evolution is correct, the *process* of evolution is a fact.

"Evolution" can be defined as change over time, from simpler to more complex arrangements. It has been happening to living and non-living matter since the beginning of the universe, and it continues as long as the universe exists.

The question isn't whether it happens, but how, and why? But that's another matter.

Yes, humans are still evolving. But it's important to notice something about evolution: when a new species evolves, the species from which it came doesn't always die out! If that were the case, there would be no other kinds of life. Humans, at the top of Earth's chain of evolution, would be the only life on the planet. (Which means that we wouldn't even be here. There would be no ecosystem to live in.)

There are still apes and monkeys and lizards and fish around. If a new species eventually springs forth from Homo sapiens, it will live along with Homo sapiens--at least for awhile. It will be a step "up" on the ladder from current humans.

Some human genetic lines will become this new species, and some will remain "only human". It's happening now, but very slowly.

It looks to me like the "next step up" in human change will be people who are naturally in tune with what we call "spirit", or "God". Their brains will be as different as ours are from a chimpanzee's (which isn't much, but it's enough), even if they look much the same.

Answer 3

In response to "lovingdaddyof2" I just want to say that Darwin's theory of evolution is just that...a theory. I has not been completely proven or disproven because there is evidence for both sides. Thus it is merely an opinion to say that Darwin's theories are "not true."

Likewise, in response to the aforementioned, changes in our genetics (also known as mutations) are not necessarily a loss of specialization by any means. Unfortunately society has conjured a negative conotation surrounding the word "mutation" but that is not necessarily true. Mutations are merely changes; for the better, for the worse, and even changes that are not noticed at all (i.e. silent mutations). Considering these mutations then, what is "specialization" if there is nothing useful for that specialization? It would merely be a change that is neither advantageous nor disadvantageous. That is where Darwin's theory comes into play; our environment plays a role in selection of what "specializations" (i.e. mutations) are useful to a species and what aren't. Thus, the environment directly influences specialization, also known as "natural selection."

So...how does all of this jabber tie into your question? Straightforward, yes, we humans are still evolving. Well, everyone is giving the example of the loss of body hair. The reason postulated is that we humans wear clothes, our environment thus does not demand body hair...and so that is not selected for genetically. Likewise the loss of the pinky toe; we do not use our feet as much as our cousins the chimpanzees do because we are bipedal and rely mostly on our hands and fingers for tactile manipulation. Also one to consider...our appendix is a useless organ within our body; it once acted to digest cellulose (plant sugars) which is seen in our plant-eating cousins as well.

So, why can't we see this evolution to a greater extent? It is often hard to understand exactly how long the process of evolution on a grandeur scale really takes. The earth is about 4.5 billion years old...and homo sapiens did not appear until about 100,000 years ago. It sure took a long time (and series of environmental events) for humans to evolve, so it must take a long time for us to begin to see any changes within ourselves evolutionarily speaking.

That's a big question, and if only we could see larger evolutionary changes in ourselves...then Darwin's theory may not be termed a theory any more... For now, though, we can only postulate as to the mechanisms that we may discover in our DNA (and may manifest on our exterior), that may some day lead to a larger evolutionary change.

Answer 4

Yes.

For example, we now know that alcoholism has a strong genetic component. Prior to the invention of the automobile, there was little pressure to select for or away from these genes. As more and more of the human population becomes motorized, these genes will be weeded out of the gene pool due to accidental deaths of the young.

There is already evidence that there is less alcoholism in the US than there was a century ago. In another thousand years, it will be even less than today. This is a result of evolution of the human species.

There are also a very few individuals who have a genetic resistance to AIDS. It is likely that this gene will gradually work its way through the gene pool in coming centuries, increasing its frequency. This also is the result of evolution acting on the species.

Answer 5

Compare the shape of the skull with specimens from 50,000 years ago, and you will see enlargement of the brain case above the eyebrows. I am certain the human species is still evolving, but we can only conjecture as to what path that evolution is taking. Humans may become smarter, or they may become stupider, but better at skills such as playing video games. Not many people read books any more, so the human species may already have attained the apex of intelligence.

Answer 6

Evolution isn't True

The evidence against Darwinian evolution is extremely strong. Let me explain. Darwin saw small variations in animals in response to environmental forces. He then extrapolated that all changes we see in animals occured due to environmental forces. This is an indefensible position. Why?

The small changes that are observed are losses of genetic information not increases in it. So rather than adding to diversity, specialization is a decrease in diversity.

This is proven out in breeding. All breeders will attest that a breed can only be pushed so far, then it becomes sterile due to the loss of genetic information.

Luckily, this loss of information is counteracted by a principal of regression to the mean. This comes from the basic principal in genetics of dominant and recessive traits. Specialized traits are almost always recessive. So when a more specialized breed mates with a non specialized one, the non specialized traits are returned to the genetic pool.

Darwin's hypothesis postulated a position that is simply antithetical to observed genetics. This makes his theory false by all scientific standards.

That is why you will not see any examples of humans or anything else evolving.

Answer 7

Yes, humans are still evolving. Evolution is so slow that you can't perceive the differences in your lifetime.

So I guess you have a wrong impression about evolution. You think it's a thing that happens in a day, but in reality it's a very long process that happens over generations of people.

Answer 8

we are, for example, we have evolved to have different characteristics that we have come to label as being based on (the artificial concept of) race.

We would all be immune to the common cold, except it keeps evolving.

Evolution is the name of a process that happens over many many thousands of years. We can obviously see the evolution of our society (at least in terms of technology, and, argueably, social structure) as we look over history. Could be that we're coming out of a juvenile stage in our social evolutionary development, and starting to cast off some of the foolish beliefs of our youth.

I also want to note that like darwin's theory of evolution, gravity is also just a theory. I guess that means it has no weight on our analysis.

Answer 9

The idea of "evolution" is that things change over a period of time. One lifetime is not enough to see some of the changes. Go to a museum and look at a suit of armor from the middle ages. Most of us could not begin to fit into it. The average height of a person then was about 5 feet 4 inches. So, yes we are changing. No, we are not growing 4 new legs or anything drastic.

Answer 10

Ok lets say that evolution is true.
It stands to reason that we are still evolving by looking at the children that are born.
Each generation as a whole not individually are smarter than their predecessors.
This is proven by the new technologies that come out.
I believe humanity has a form of genetic memory.
The smarter we get the more we pass along to the next generation.
