Now one day, a cell splited abnormally. The middle part of the cell left the outer part and became two different kinds of cells, a male cell and a female cell. Please wait to see the picture move.


The reason for this abnormal split could be: radiation, lack of nutrition, germ infection,etc.

Now we have a male and a female. Male can't reproduce since male's negative charge is too strong and avoids it from splitting. A group with a very strong central power does not split.



Afemale has the potential to split (reproduce) but does not split until it receives some negative charges from the male.



So a male must mate with the female in order to inject negative charges into the female.
