Did you know scientists know less about the human brain than they do about our solar system
Researchers found that regardless of the season, the turnover of serotonin in the brain was affected by the amount of sunlight on any given day. And the levels of serotonin were higher on bright days than on overcast or cloudy ones. In fact, the rate of serotonin production in the brain was directly related to the duration of bright sunlight
did you know: sunlight exposure increases serotonin levels?
Interesting! This explains why in a food class I took, when the professor was talking about why asparagus makes your pee smell, a couple people were like "huh durr waat?"Did you know that eating asparagus causes your urine to have a strong pungent aroma, but only about 1/4 of the human population has the ability to actually smell the odor?
Where'd you hear that one?About 10k years ago or so everyone had brown eyes. Then one single ancestor had the gene mutate to produce blue eyes as opposed to brown eyes. Since Blue is recessive to Brown he/she would have had still had brown eyes as would direct offspring, but some of those children would be carrying the recessive Blue gene. Finally generations later some of the original mutant's great great grandchildren bumped uglies and the first blue eyes people were born.
Long story short, every person who has Blue eyes is family and decent of one mutant who lived several millennia ago.
It's the same thing. I think blue eyes has to do with a switch a certain distance from albinoism so that we don't go completely white just the eyes blue. I don't have time to look it up in any more detail at the moment.So where do green eyes come from?
