Problem with Evolution?

Question

Evolution states that humans and animals take millions of years to change to adapt to weather or survival.

The problem is that humans and animals actually have a short life span. Dogs don't live more than 14 years and humans live about 65-80 if they are lucky. How can any changes occur in such a short time? Plus humans back then lived shorter lifes do to deases and unhealthier diets. So even after a million years... why would changes occur in a species, if they don't occur in the individuals lifetime?

andrew w, that is probably do to the fact that we inject animals with Growth hormones to make cows and pigs and other animals grow faster. Then we end up eating that meat full of hormones.

Answer 1

One is able to change his genetic limitations only to a certain level while being alive. The main key to evolution is the fact that genetic modifications are being strengthened in the children of an animal. Mutation occurs after several generations of children. This is proven, because mental illnesses or diseases can become stronger in a parent's child. Also, if I p.e. example am a good runner, if I ran marathons, than my children may have this talent as well, and it can be strengthened.

Hence, the longer the life span, the slower a species will adapt, as they will breed at a later age. Insects p.e. die quickly hence they breed more quickly and will mutate faster. They, however, quit evolving, because they either cannot adapt to the environment, or because their adaptation is not required. The reasons why insects such as flies don't adapt, is because they must first survive a struggle and then breed in order to give significant modifications to their brethren. This doesn't happen as they get smacked before they breed.

Answer 2

Actual scientific problems. I am working on becoming an actual scientist, yes. But it is important to understand that you do not need to be a scientist in order to understand the processes and evidence. The reason most 'Christians' had a problem with the heliocentric system was because, at that time, they (the Church, Catholic Church) had made the mistake of accepting a system given to them by an Atheist astronomer and been teaching it as actual church doctrine. This was a mistake of the Church hierarchy bending to the changing ways of man and not adhering to the biblical teachings. The Catholic Church has once again 'accepted' evolution (molecules-to-man) as being non-contradictory to the Bible. They have made the same mistake again. I will not make their mistake. One thing you probably don't know is that the geocentric system actually had an explanation for every variation from its expected model and it seemed true to the casual observer. It is only when you get into the real science amd simplest explanation, that you come to the truth. God bless

Evolution is a change in the gene pool. It could take millions of years, or it could take a couple generations. The shorter the life span, the quicker the evolution. Actually, it has more to do with the age of sexual maturity and the length of time a species has to reproduce more than the amount of time they spend alive. The longer a sexually active, reproducing individual lives, the more they contribute to the gene pool. If they have a trait that causes them to die before reproducing, or even if chance causes them to die before reproducing, they don't add to the gene pool. It's really quite simple. Evolution is just as much chance as it is "fitness". probably moreso actually. It has nothing to do with improving. Evolution isn't a conscious thing or a judge and it's not about getting better, just about changing- the gene pool, not the individual. Whether you die because you can't digest the only food around or you die because a tree freakishly fell on your head, you're still removed from the gene pool. Likewise, whether you live and are able to reproduce because your body is perfectly formed and adapted or because medical science kept you alive and managed to unite egg and sperm in a petrie dish, you're still contributing to the gene pool- for better or worse.

Because evolution is change within a genepool, not change within an individual, what happens in an individual's lifetime is largely irrelevant (unless it kills them) there is, however, Cultural Evolution, which is quite different and has very little to do with genetics (besides the way genes affect the ability to do things that affect culture), and that can happen within an individual's lifetime. In fact, individuals can bring it about. Many individuals and groups have been influential in cultural evolution, for better or worse- Martin Luthor King Jr., George Bush, Nirvana, the KKK.

I find most people who have a problem with evolution simply don't know what it really means.

Answer 4

It's because of our short life spans that we are able to adapt faster. Shorter life spans mean shorter time spans between reproductie periods. If we have more children, there is a greater chance of a mutation in the DNA. If it has a positive effect on the human, then he will survive better than the others and pass his genes on to the next generation. Why do you think they use flies for these kind of experiments? They only live a month!

Mahal! How can you say we all evolved in the same way? We have whites, blacks, mexicans, native americans, short people, tall people, fast people, slow people, smart people, stupid people, all different kinds of people! We haven't been evolving in the same way. It's just that in our current society, it's become a mixing pot of ethnicities.

Answer 5

Changes don't take place in individuals, they take place in species. Species, you will observe, can last millions of years.

Individuals pass on DNA and DNA constantly changes. It's changing in you right now. So the changes DO occur in an individual's lifetime. They are passed on and over generation natural selection concentrates them into a main characteristic.

You should know all this if you're going to talk about evolution. If people paid proper attention in their science class and weren't bullied into thinking that evolution was somehow wrong because it didn't quite allow for their fairy tales, this sort of question wouldn't need to be asked. The education system is seriously wanting.

Answer 6

You're really intent on digging yourself into a hole, aren't you?

Anyone who thought that this question represented a "problem with evolution" would have to be so breathtakingly ignorant that there would be no hope whatsoever for that person to ever understand, well, much of anything. If you are really serious, you're in so far over your head that your ankles are probably coming out the other side. Mahal is right there with you.

It seems that the basic modus operandii here is for creationists to say astonishingly ignorant things with as much bluster and insult as they can manage, the rest of us respond either by pointing out the obvious errors or by noting the depth of ignorance, and then Christians whine that they're persecuted. To the extent that Christians are insulted on this board, the blame lies entirely with people like you and Mahal. You just can't act this badly and expect honest people to pretend not to notice.

Answer 7

It's not that each individual in a population changes over their own lifetime. Say there was a group of animals and a predator moved into their environment, and only the ones who could run fast were able to get away. Then they are the ones who would survive and pass the traits for running fast onto their offspring. Eventually all the slow ones would die out because they wouldn't survive long enough to be able to pass on their genes. That's roughly how natural selection works

Answer 8

The human species evolves. The changes happen between generations not during someone's lifetime.

Answer 9

Just because a human lives for 65-80's doesn't mean that he isn't a product of evolution. It's in our genetics and as we give birth and keep reproducing then thoes genes are the ones evolving.

Answer 10

The idea is that small changes accumulate over time. Each generation contributes one small change, and after a thousand or so, you have a very different creature.

The problem with this is that for evolution to be true, all human beings, for example, all over the world have been evolving in exactly the same way, developing exactly the same new traits at exactly the same time for at least a million years.

That is simply amazing.

Proof?

Look around. There is only one species of human beings. That's all there has ever been as far back as written history. Every time explorers ever ventured out and ran into other humans, they were all (without a single exception) homo sapiens.

Whales had no problems developing dozens of different species. Neither did sharks, ferns, bears, dogs and cats, pine trees, etc.

Can you imagine the odds working against the theory of evolution, and yet people take it all in as if it's the god-aweful truth! It blows me away!
