Welcome to Gaia! :: Evolution: Fact Or Fiction

Evolution is like this:

The world is a tough place to live in. Whatever factor increases the ability of its bearer to reproduce successfully, or avoid destruction if reproduction is impossible, will necessarily become more common throughout a population.

Now, because situations change over time, what factors lead to success (and therefore are becoming more common) will be changing over time.

Let's say that a population of quadrupedal mammals has variation in a given heritable non-sex-linked trait... let's say, leg length, right? So we take them and we force them to live in an environment with dense, spiky bushes that come just up to the bellies of median-height animals.

So the males who are at the median or shorter are going to suffer injury to their reproductive organs - basically, their balls are going to get stuck full of thorns. They won't be able to breed, while taller males will be able to breed because their balls are not getting stuck full of thorns. Because height is heritable, at least partially, then over time, the population will tend to get taller, in both sexes: females who are short will have trouble mating (do I have to draw you a picture?) and thus will be reproductively unsuccessful.

So tall genes mean a greater likelihood that said genes will be passed on. Thus, tall genes become more and more common. Now, if we postulate that the bushes with the spikes and stuff have been undergoing selection to get even taller, then the animals are going to be selected even more harshly. They may even become so different in height from their parent stock that mating becomes almost impossible, except with freakishly tall examples of the parent stock.

God is the one that makes everything move. the whole world...no the whole UNIVERSE revolves around God our creator.
and the bible existed way before 300 YEARS ago remember Jesus told his disciples to write down whatever they see? that's how the bible was created, through the prophets, Christ and his disciples.

But in my opinion, the bible is fact. so is evolution. [lol] and we did not evolve from monkeys, we evolved from neandethals, and "Lucy"

He probably meant around 300 BC, when the NT was canonised.
As for who wrote it, nothing in it was written by Jesus' disciples. All of it was third hand accounts of his works at best, and was written over the following few hundred years.

Neanderthals are not ancestral to humans, they're more of a "cousin" species.

Not quite.
"Theory" here doesn't mean any uncertainty about it (in science everything has a degree of uncertainty, just not always a reasonable degree of doubt), it means that we have a very well-supported idea that describes the mechanisms of observed fact. I can't count how many times the word "theory" has been defined in this thread. Please don't drop in on a several-hundred page thread just to repeat something that's already been dealt with. It perpetuates wrong ideas.

did you mean galapagos islands, XellosRei-chan? xp

AnswersInGenesis is not only an unreliable source, they're a reliable source of lies.

Yet another creationist site that tries to discredit scientific advancement that supposedly says they are wrong by using ignorant misunderstandings.

If you used your brain then you would be a fool if you believe that site
