A Universe Without ♂ (males)

A Universe Without (males) : Beware those male chauvinists who consider that the world can’t do without them !!!!!!!!!!! Indeed, this article is going to have a mixed reaction from readers . It will come as a shock to the males suffering for superiority complex but as sigh of relief to their female counterparts.Nature is full of examples where only female members are capable of producing their progeny and which completely lack male members by a phenomema called Parthenogenesis(Virgin Birth, u can compare it with nature's way of cloning). Few examples are millipede Nemasoma, cockroach Pycnoscelus, spear-winged fly, Dipsa bifurcate, aphids(honey bees).But the most interesting comes from a whiptail Lizard.In 15 of the Cnemidophorus species there are no males. How much boring it may sound , but there are some advantages to a parthenogenic lifestyle: -All members of species can lay eggs and reproduction is more efficient -Good mutations are passed on more efficiently in clones than in sexual species -You don't waste a lot of time and energy searching for a mate . Then why do the nature created different sexes??????? Some Things to Think About 1.Are there any advantages to having 2 sexes? Will males in our species someday also disappear like those of the whiptail? Quite sad, but very very probable………..you can post your thoughts for this blog.I will be updating you more in coming blogs till then if you are male, keep praying that the day never comes:-) For Females , Time for celebration. Rejoice. 2.Why is nature still experimenting with so many types of reproductive strategy? Answers any one?
