i do think there are some massive unexplained bits in evolution, that all scientists seem to gloss over. Most quoted example is the eye, which has
countless genes to make it, but would need them all to work. There would be a selection pressure against half an eye.

you assume that humans are more "evolved" than monkeys just because we're intelligent.
In truth a monkey in a zoo and you have evolved equal amounts from its nearest common ancestor.
We didnt evolve from the animals you see around you. Stand in an imaginary line with your father on your right hand side, and his father on his right
hand side and so on and so on. Then have a separate imaginary line with a chimpanzee and all its fathers and fathers fathers. Eventually you will
reach a point where there is an individual who is a father for both lineages.
that is evolution.. you don't expect or need "middlemen" in between the animals that are currently alive.
I'm sorry but that is just wrong there has to be middlemen if evolution is a factor in the make up of a human. The monkey that we started out
life as is the same in priciple as the ones you see today they have evoled slightly yes but in the same way that man has.
saying we come from a monkey that just so happens to not be around any more is like saying God and Jesus are real and the fairy tale story that was
wrote in the Bible is 100% true.
It cannot be proved there are no signs of any monkey in todays world that even looks like a human why not?

it's interesting that the eye gets quoted so often when it's one of the best examples of adaptive evolution.
1. A cell evolves which produces a chemical signal when light falls on it. This is fairly straightfoward as the energy in light can simulate various
reactions to take place. This cell would be selected for as it gives the organism greater functionality.
2. Clumps of these cells would be selected for as they would give stronger responses to incident light. You now have a basic retina.
3. If these clumps happened to form in recesses on the organism then they would again be selected for a this allows directionality of light to be
assessed. The deeper the recess the more accurately you can tell the direction of the light. You now have an eye socket.
4. If the recess develops a coating then the sensitive cells will be protected again giving an advantage. The thicker this coating the more protection
it offers. You now have the main consitituent of an eyeball.
5. If part of your protective coating becomes hard and it's clear then you have a basic lense which focuses light and allows some detail to be
seen giving you yet more of an advantage. Although very basic this is now what you would describe as an eye.
Now these are only the key evolutionary milestones, this happened over millions of years in a 2 steps forward 1 step back fashion in a number of
successive organisms.
A key point too is that the eye is RUBBISH. Those first photosensitive cells actually developed upside down facing away from the light and this is an
error that has been passed down into our eyes. Light has to travel through to the back of the retina before it is detected! But because any ability to
detect light gives an advantage it has proliferated.

yqusta, Nottingham probably shouldn't have given me a degree on the subject then !
If you could see evolution then you would see the imaginary lines of individuals I've described. That is just what evolution is.
If you understand that concept then why would you expect there to be links between modern humans and modern chimpanzees that are alive at the same
time? There is a link, it lived thousands of years ago and you can see it's fossils in a nearby natural history museum

Blind spots in the eyes, hernias, back pain from recently (evolutionary) walking on 2 legs, ectopic pregnancy, a throat used for both ingestion and
respiration (increasing risk of choking). So many flaws to chose from!

it moral.

Did anyone see the C4 series where they dissected an elephant, a whale & a giraffe? They showed how the nerve that controls the vocal cords
(circa 6 inches from the giraffe brain), goes all the way down to the chest, around the heart and back up again. Doesn't matter if your a small
fish, but it is poor design for a giraffe. However there is no evolutionary pressure to reroute the nerve so it stays following it's bizarre
route.

Your degree does not mean the theory is correct as it is what it is a theory i could just as easily study a theory of evolution that is different and
it could be argued that that theory is correct.
I understand the theory I just don't have (nor does anyone else to my knowlage) any solid proof.
Yes I agree totaly that evolution did, is and always will happen that is a fact and as you say if I were able to line up all of my fore farthers there
would be a difference from start to finish but that alone is not enough to prove we were ever from one type not saying it couldnt happen but as with
god until proven its just another point of view.

However, some points of view make sense, while others just really don't.
It's generally accepted that its not really possible to 'prove' any theory - it is only possible to disprove them. The ones that
stands up against common sense and proper scientific analysis generally become the accepted theories, and those that can be disproved or replaced by
something more sensible tend to disappear.

I remember those Faraday lectures showing some sea animal that still used an eye that was a few "steps" of evolution behind most of ours..
