| Questioning | Evolution I believe that the evolutionary theory is the most "logical" theory for how life formed, but I was thinking about something a minute ago. The answer to this may be common knowledge, but I just haven't study into the specifics a whole lot. Ok, if humans evolved from apes, why is it that nowadays there are still apes, there are humans, but not any creatures in a stage between "ape and man"? ---------------- Noah Moses "And, when he shall die, take him and cut him out in little stars, and he will make the face of heaven so fine that all the world will be in love with night, and pay no worship to the garish sun."--William Shakespeare | |

In my eyes we are past the time where evolution is merely a "theory", by which I mean that there is so much evidence for both spontaneous and long-term evolution that evolution can safely be regarded as something that actually happens. Now that does not mean that all the differing theories _about_ evolution are correct. For example, the debate is still on whether birds actually descended from dinosaurs or not. There is also much debate about how the cambrian explosion came about and many other things. As for whether human beings descended from apes - for a long time there was talk (well, I guess there still is) about a so-called "missing link" which would finally prove that humans descended from apes. One way to go about this is to draw a "family tree" (more like a bush, though) and try to trace the lines back to commmon ancestors for both apes and man. It all boils down to a genetics debate and also how "lucky" we are when it comes to digging up old bones... Here is one article about this: Genetics may help solve mysteries of human evolution The web is full of good sources on evolution, here is one place to start: Evolution links at U of Toronto Tormod ---------------- Your Friendly Neighborhood AdministratorWant to sponsor Hypography?

| Thinking | Evolution I have several questions about evolution: 1. Why don't we see it happening now - whether it be spontaneous or longterm evolution, it appears to no longer take place (at least we cannot observe it happening now). There have been no significant physical changes in humans or animals in thousands of years. Why does the evolutionary process just seem to stop? 2. Have there been any experiments conducted to see if scientists can force an evolutionary change in a plant or animal - what I mean by evolutionary change is not simply changing a solid colored cow into a spotted one but change one species into another. I realize that some evolutionary changes take many many years but some are spontaneous and could realistically be done in an experiment. 3. Why is it that no other species has human intelligence (but humans). 4. | |

| Hypographer ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | Evolution 1) On what basis can you say that we do not observe evolution taking place in humans any more? I assume from your question that you think it has happened before? 2) Ever heard of banana flies? 3) Why do humans have tail bones if we don't have tails? I would even add some questions to your list: why do only human beings pose a threat to the environment of the Earth if we're bestowed with this incredible intelligence? Why didn't we pose this threat 2,000 years ago (a blink of an eye in cosmic history)? Or did we? Could the explosive expansion of human culture be seen as evolutionary? Is a human being of 2,000 AD for all practical purposes the same creature as a human being of 10,000 BC? Tormod ---------------- Your Friendly Neighborhood AdministratorWant to sponsor Hypography?

| Thinking | Evolution [ Quote:
How do you define evolution? My understanding is that evolution invovles the addition of new genes to someone's genetic makeup. Quote:
-We did not have the technology 2000 years ago to pose a threat to the environment (toxic waste, pollution etc). Through human desire to make life easier, more comfortable we used our intelligence to create things like cars that pollute the air. -I think the expansion of human culture is a product of our intelligence. And our intelligence is something that we can develop but it does not evlove. By my questions above, I do not mean to imply that some for of evolution did not take place. There is a lot of evidence to suggest that it did. But I don't think it is the only answer. Evolution falls short in explaining human intelligence and, more importantly, human behavior. As your comment about man's threat to the environment suggests, human behavior is far from exemplary. Humans can do awful things to each other (and sometimes very good things). Evolution does not seem to explain this. | |||

| Thinking | Evolution The reason why we still have apes and not half bred or all humans and no apes is due to one big reason. Apes came from the western part of central Africa and naturally, they migrated. There were many groups that had migrated and due to the challenges they faced upon, some evolutionised into humans, human-like species, and other variety of species of apes.

Evolution is not addition of genes. It is adaptiation to the environment due to mutation, specialisation and development of skills. Quote:

Exactly where does evolution fall short in explaining human intelligence? At what point did humans enter the world, and when did they aquire the intelligence that they then for some reason were able to improve upon? Did every single human being alive at some point in history wake up one day and say, "what is this new thing? It must be intelligence!". Or are you suggesting that evolution has occured with all other beings _except_ humans? This is not clear to me.
