Questions in bold black, answers in bold red.
1) Lets say we did evolve from ape...why did we need to evolve? We have no fur, cant climb trees, aren't as fast and cant really survive in the jungle areas too long...It seems like we devolved in a bunch of ways?
First of all: COMMON ANCESTRY!!!!
All animals evolve, not just humans. As for needing to evolve, we don't need to. Evolution is a natural occurrence that must naturally occur in a system of genetic life that involves mutation and variance. Devolved? We're the most dominant species on the planet. Why do you assume things like speed, fur and climbing trees to be the endpoint(s) of evolution? Here's a hint, there is no goal of evolution. The traits that best enable the propagation of a species live on (natural selection). That's it.
2) why is it that humans can basically eat ANYTHING, including apes....and apes are strictly plant life?
Apes are omnivores.
3) Since a species is commonly defined as a group that can interbreed, it seems like fossils could never be identified to the species level because we can't observe how they interbreed. How do scientists determine what species a fossil is if it looks similar to another fossil but is a different size or slightly different shape? When scientists disagree with the classification of a fossil, who decides where it belongs?
What you described is called morphology. The answer to the question, at least in part, is DNA.
4) The human nose has a prominent bridge and an elongated tip which is lacking in the apes, and man's arms are very short in comparison to the arms of monkeys and apes. The arms of apes hang down to the ground and like its legs, are used for transportation...quick movement & climbing...another de-evolution?
See answer 1. Stop thinking of evolution as though it has an endpoint.
5) Human babies are far more helpless and dependent on their parents than any of the infants of apes and monkeys...What's up with that? Baby apes can move and climb very well only after a few weeks.
The fetal stage in humans is not complete at birth, that's why. Our brains/skulls get too large, so we are born earlier to compensate. Otherwise, we couldn't make it out of the birth canal.
6) If it is inaccurate to say that humans evolved from apes, but instead we should say all apes and humans have a common ancestor, what did the ancestor look like if not like an ape?
Okay, so if you know this, why did you phrase it differently in the beginning? Anyways, why do you equate looking like something with being that something, yet earlier you stated that fossil's can look similar to others fossils? Your question makes no sense. You say we descended from an ancestor that we have in common with apes, yet what did the ancestor look like if not like an ape? That's inconsistent. You're not actually saying what was it, but rather, what did it look like. You are making the vague implication that if it looked like an ape, it must have been an ape? Huh? Do you even know what you are asking here?
Anyways, isn't it quite obvious? You'd assume that they looked like a cross between humans and the other great apes to whom they gave rise.
7) Why is it that only apes evolved like we have? Why is it that we are the only ones that can split the atom, create gorgeous symphonies and 'I Have a Dream' Speeches, map & conquer the galaxy? It seems like only man is free to make real choices, and it's not like we are the only smart ones...Animals are free to do what they are instinctively programmed to do or what they have been trained to do. Men can make plans and decisions and choose a course of action....but how did we evolve to be THIS smart and THIS free?
Why is it that only cheetah evolved like they have? Why is it that they are the only ones that can run so fast? It seems like only cheetahs can run so fast. Cheetahs can run SOOO fast....but how did they evolve to be THIS fast?
Do you get my point? I hope so. Anyways, the answer is simple: prefrontal/frontal cortex.
8) Why is it that only men are able to train and tame other animals?
We're not. Ants can herd aphids, although, even if this were true, and I actually thought it was until I read this online, I don't see how that would be difficult to understand, or contrary to evolution. Presumably, it would boil down to intelligence, would it not? That's how I was going to answer it, until I read the ant thing. We have evolved to possess great (relatively) intelligence.
