On that point I disagree, and still do, however, with the constant nattering about a member that has moved on ended that conversation prematurely, there is still much to be said and debated. That Alien was indeed a fake, but not because it was anthropomorphic in shape.
Now I'd like to say, that member's status does not contribute to the thread, please refrain from mentioning him so others may enjoy a conversation.
Now, where Id like to start is by continuing with the contribution by Lost Shama, I will follow up with a reply to Stereologist, which I felt requires a reply.
As you did not get the opportunity to reply to Lost Shaman Stereo, here is your opportunity:
Your second point, is kind of bunk IMO. Have you ever seen an elephant weave some grass into a Basket to carry something? No. Its because they can not. Just because you can Imagine something does not mean it could be true. There are some serious constraints to what is physically possible. For example chimps have hands and arms like ours and they are even stronger than we are, but a study was done where an Anthropologist spent 5 years trying to teach chimps to knapp simple stone Tools. The Chimps simply can't do it! There wrists and Arm muscle structure just do not allow them the precision needed even when they know what they are asked to do!
On the otherhand almost any Human can knapp an arrowhead if you bother to teach them even though this is an almost a Dead art. Its because our wrists, arm bones, muscles, and even our Brains are perfectly adapted to do this type of delicate work.
It is not just a bunch of random mutations that allow us to do this. It is that tool use was so advantagious gene expression or some other mechanism must play a role.
Your third point, I'm not sure I get what you're saying. I agree with psyche in that there is an inherent Goal of Evolution. That is to have viable offspring.
Also #3, is a perfect example of your imagination running wild! Choking is not a real problem, but if we did not have a common pathway the immune system would have to work so much harder and patrol much more area. It makes no sense. You just imagine chocking is bad. So you assume eating and Breathing should be sepearate. I think such a creature would just get sick more often and if you got something stuck in your throat then how would you dislodge that if your lungs are employing a seperate pathway? Have you even thought about that?
