This could be noticeable in one of the 3 places mentioned in the last question - in fact it was first observed there.
The World's largest population of these is in one of the places mentioned in the last question - or at least the modern name for it.
So, to summarize so far: It is a sexual advantage to be 'darker' in appearance. The World's largest population of these is in one of the places mentioned in the previous question (not Heligoland !). What proves to be an advantage in one sense may be a disadvantage in another one - namely heat stress. Those with the highest testosterone levels may actually laze around more as a consequence.
Nope, nothing to do with elephants Yorkie. Amongst this species it is an advantage to be brunette - ie. you get the pick of the ladies. Also, being brunette is not a matter of pigmentation but rather a sign of health and virility. However this comes at a price. At sea level this phenomenon is less observable.
It is indeed the Lion BB. Amongst males the mane gets darker with age - and is an indicator of the vigour and health of the animal. Lionesses, when given the choice, will choose Lions with darker manes. So brunettes have more fun in this instance. Lions with darker manes are also less likely to be challenged by other males. Whilst having a thick dark mane is an advantage here, it is also like you or I wearing thick clothing in the African heat and infrared has revealed that those vigorous full maned, darker lions have a problem with overheating, which is why they spend 20 hours per day conserving energy. The principle of dark maned lions having an advantage is more observable at higher altitudes such as in the Serengeti National Park (Tanzania) which is largely over 1,000 metres above sea level and seldom goes above 30 degrees. At sea level there are even species where the males are maneless. Over to you.
I know that ultras of Malmoe FC knocked the nose off the statue of Zlatan Ibrahimovic but I don't think the Swedes execute people for this
