For millions of years, humans have been getting faster, smarter and more developed.

Is this process coming to a halt?

Are humans now becoming slower, thicker and fatter ?

For years, scientists have been debating whether or not there is actually any evolutionary relationship between the Spoon and the Fork.

Then, a watershed moment in science happened. The Spork was discovered.

It happened in a fast food establishment in the 50's.

There were earlier tales of a hybrid Spoon/Fork, but this was the first time that one was sedated and placed in captivity where scientists could study it first hand.

Before this event, most mainstream scientists merely put the similarities betwix the Spoon and Fork as a case of convergent evolution.

Critics pointed out that they could not be related due to the drastic differences between the heads. While, they did concede that the handle (or thorax) of the Spoon and Fork was essentially identical, they pointed out that bats and birds both have wings, yet no one would say they are directly related.

This question came up the other day in conversation, and has me stumped. My assumption is it would be some type of archaebacteria, but I really have no idea. I know that some prehistoric fish and plants have survived the maas extinctions, but I do not know which one has been here the longest? Thanks!!

In my textbook they say that
2H+ + 1/2 O2 = H2O
since there are electrons from both NADH and FADH2, it is in fact twice as much:
4H+ + O2= 2 H2O

my question is how does 4 electrons and 4 protons(H+) combing with O2 form 2 H2O?
does this mean that H+ becomes H(with 1 electron and 1 pronton, and no longer becomes an ion?) In otherwords why are protons necessary to form water?
