This sexless word called Parthenogenesis

The Komodo dragon lives in little islands and therefore can be quite lonely. If the female does not find a mate, she may die and leave a dragonless island. Therefore this amazing reptile lays eggs which hatch to produce young, without a mate. This is called parthenogenesis. The young are all male. They grow up and mate with her to produce more genetically diverse and sexually fertilized eggs.

Insects, reptiles and fish including sharks make use of this to keep going. With mankind against these creatures, they may all start doing this more often to keep their species going.

It is sad that birds and mammals - the warm blooded creatures, do not have this ability. I wonder why? The answer is blowing in the wind.....
