But Lamarck did mention an example with a giraffe, didn't he?
Generally speaking, the more people talk about "being saved," the further away they actually are from true salvation.

yah, lamarack also gave a theory about the giraffe, but about his theory, it describes that the reason why the girrafes do have long neck, its bec they stretched their neck until it got long then there was a heritage form got from them and thats what is according to his theory while charles darwin's theory about the giraffe is that, there were 2 class of giraffes before the long and short necks, because i think in my understanding, the survival for living for the shorter necks of giraffe were very difficult and they died while the long necks of giraffes have survived using their long necks, they used it in reaching food in higher places. then the heritage was develop. thats all folks!

can u give me the details about the theory of charles darwin about the giraffe????according to his theory while charles darwin's theory about the giraffe is that, there were 2 class of giraffes before the long and short necks, because i think in my understanding, the survival for living for the shorter necks of giraffe were very difficult and they died while the long necks of giraffes have survived using their long necks, they used it in reaching food in higher places. then the heritage was develop. thats all folks!

The reason that you have given is right but the extra long neck of giraffe cannot be told by such a reason, according to me is because the giraffe lived in a commnity with various heights and a constant mixture of genes produced more variation in extremes of size considering an antelope as the giraffe's ancestor means long neck more trouble as also in an equatorial region.I am saying an equatorial region because the okapi survives in it and an okapi's ancestor cannot be an antelope according to me giraffes are much more related to cows.

Re: Some examples relating to my original idea

Okay, consider this example. Take the case of stray dogs. I have not really done this experiment. I'm only predicting outcomes here. If you raise your hand to mimic the gesture of throwing a stone, notice what happens - the dogs takes caution. It runs. Now let me raise your curiosity further: suppose this dog for some reason has not had exposure to humans or other dogs at all since birth. It is some how trying to live, and it is doing rather well at that. Now, out of the blue, let some human being mimic the gesture of throwing the stone at him. What will happen now?

I predict the dog will take to its heels.

Now why don't disprove me and explain this in the context of evolution. It would really help.

One other fact of life. This time consider new born babies. As soon as infants are out of their mother's womb, they are cute silent creatures to look at, until they fall hungry. The mother then gives them their breast.Now IT IS A PERFECTLY NORMAL THING. But strangely they know how to suckle as well. Isn't that food for thought? How do they know?

What is the issue with the idea of survival here? Say that the infant did not have the software to suckle. What then? Would it live? :?:



If u came across genesis and microbiology i would not rise this question..
all these behaviour are all already coded in genes of all species. all mamalians are coded in their genes how to suckle since mamals start appearing at the end of cambrian period ie end of jurassic period.so its more that 200 miliions years of programing , even if the baby wants to erace the software it cant do that bcz its all built in it.
your predictions are wrong!!!!!!! mightbe it will take millions and millions of years for a dog to forget that code built in it to ignore stone throwing man .... dogs are canine family , if u really want to test ur idea go to wild , go to cold siberia and try to through a stone at wolf there , then u would know what evolution did on living things...
its all natural selection

Yes I'm still around (sorry to take the thread on a tangent)
I was working for the BLM out in the desert all summer, so I didn't have access to the net. Now I'm back at school though, so I can post more.
Still, I probably won't post as much as I used to, just because I'm so darn busy w/classes, job, and my club.
