The fairer of the species


It is interesting how sexual dimorphism in the class Aves generally results in the male as the more gaudy and extravagant of the sexes. There are famous reversals of this general rule such as the phalaropes and in many species there is no plumage sexual dimorphism, such as Tree Sparrow. Well, I was just thinking-who is the fairer of the human sexes- is it the male or the female? Generally sexual dimorphism represents some kind of different role play. A gaudy extravagant male in a bird species usually means the male spends so much time adorning himself and is so conspicuous to predators that he is of little use to her when it comes to raising her offspring. Sexual selection creates an arms race amongst the males to become the most ridiculous dresser uppers, singers and dancers. This is not helping me work it out????

Humans are strange- it is like they are all the animals rolled into one- we can fly, dive, burrow, walk, run, swim, eat vegetarian, eat meat, eat nearly anything, males and females sing, males and females dance, both hunt, both gather, both farm, humans can work in groups, work alone, they can have 100 partners or have one partner, two wives, ten husbands, no wives- there are few rules. It would be a nightmare trying to write a HBW style summary of human sub-species and distribution, descriptive notes, habitat, food and feeding, breeding, movements and status and conservation. It will be like -everything goes.

It seems entirely plausible, if not inevitable. One of the rolex replica things I find fascinating, is that the the luxury industry is so deeply concerning themselves with the Apple Watch and rolex replica sale smartwatch devices. Perhaps it is Apple's fault for knocking on their door, with the 18k gold Apple Watch Edition, or maybe, they just want to get in on new trends. I would have guessed that the luxury industry might wait a few rolex replica sale years for the smartwatch industry to mature, before deeply concerning themselves. It isn't as if traditional luxury watch makers are suddenly going to develop software and electronics hardware. Their forte has always been about external design and rolex replica uk materials. Yvan Arpa has been responsible for a number of luxury hublot replica uk watch ideas, that span from brilliant to just totally wacky - and that is why we love him.
