Quranic Claim of Everything Created in Pairs

Jump to: navigation, search

Glory to Allah, Who created in pairs all things that the earth produces, as well as their own (human) kind and (other) things of which they have no knowledge.

And it is He who spread out the earth, and set thereon mountains standing firm and (flowing) rivers: and fruit of every kind He made in pairs, two and two: He draweth the night as a veil o'er the Day. Behold, verily in these things there are signs for those who consider!

...Scientists have discovered how a microscopic organism has benefited from nearly 80 million years without sex. ...Bdelloid rotifers are asexual organisms, meaning that they reproduce without males. Without sex, these animals lack many of the ways in which sexual animals adapt over generations to survive in their natural environment....Humans and most other types of organisms reproduce sexually - resulting in two copies (or a pair) of each chromosome within a cell, one copy inherited from each parent.^{[1] [2] [3]}

..many flatworms appear to hunt and fight for mates. Each worm is hermaphroditic, containing both ovaries with eggs and testes with sperm. Some even have two penises and one or more genital pores for receiving a unique, two-tailed sperm delivered during copulation... engaging in some odd reproductive behavior -- referred to as penis fencing. During penis fencing, each flatworm tries to pierce the skin of the other using one of its penises. The first to succeed becomes the de facto male, delivering its sperm into the other, the de facto female. For the flatworms, this contest is serious business. Mating is a fight because the worm that assumes the female role then must expend considerable energy caring for the developing eggs.^{[4] [5]}
