the memory is enhanced because the neurons in your brain form new connections and we remember things for tests and such because when we study we make those connections stronger. Hope this helps.

Human beings developed various abilities from the necessity of keeping themselves alive.Imagine how much humans exercised their brains in order to become the most powerful race of the planet.I think is a matter of exercising the memory.

I've read that protein, which was apparently added to human diet 2 million years ago, lead to a rapid increase in brain size. The most likely source? Humans started eating fish along the east coast of Africa.

Out of a population of humans with various memory powers, the ones whose memories were better didn't fall down so may holes (because they remembered where they were) or chase so many sabre-toothed tigers (because they rembered seeing Og get eaten), so when the survivors bred, they had an increased chance of their offspring having better memory powers. And so on and so on. Self-selective breeding.

memory in the human brain is held in 2 little organs called the hippocampii. when they get smaller, damaged and stop working we begin to have serious memory problems. they are in charge of both long and short term memory--if you really want to kno how it works look up hippocampus in your search engine...

If you are referring to over thousands of years, it is because the areas in the brain moved around creating changes that made us who we are today.

Did? When was it done? However, memory saving technologies are being developed in the labs.

in the same way that a body-builder will tone and strengthen his body, the human race has spent thousands (if not tens-of-thousands) of years constantly challenging our intellect starting with the first use of our opposable thumbs.
