"The vibrations provided some rough informations about the surrounding ambient
Step by step they turned into the inner ear"
So you have scientific evidence and proof of this ?
Please post it.
"All the ancienst animals had just an non articulated opening for the mouth, no jaw "
Really ?

Clearly , the T-rex has a jaw
"The tip of the upper jaw was U-shaped (most non-tyrannosauroid carnivores had V-shaped upper jaws), which increased the amount of tissue and bone a tyrannosaur could rip out with one bite, although it also increased the stresses on the front teeth."
How far back are you going ? Dinasours are our oldest fossils we have , and they apparantly had jaws. Please post some references to this.
"we even have the remainings of a tail at our back!"
"Humans have a tail bone (the coccyx) attached to the pelvis, in the same place which other mammals have tails. The tail bone is formed of fused vertebrae, usually four, at the bottom of the vertebral column. It doesn't protrude externally, but retains an anatomical purpose: providing an attachment for muscles like the gluteus maximus."
So we have a tail bone , but it has a purpose , how can you assure that we lost our tail through evolution (or apes did , since we come from them right)yet kept the tail bone ? In fact, there really is no reason to loose the tail , it's a great adon , it comes in very useful for monkeys , why would apes and humans have just stopped having their tail ? Thats like us evolving even more in the future , to only have one eye and one arm , is this how "natural selection" is suppossed to work?
I find it insane that people argue for the right to be a part of the ape/monkey family tree. Because you know evolution states we are apes , not were , ARE , just a different evolved type, what are you gonna argue next ? That we are actually evolutioned turds ? LOL
Just the idea of our "intelligent" people arguing and fighting to believe and make others believe we are actually monkeys is something out of this world. But somehow , that is exactly the case.
