Eusociality among Bees

This results in the males becoming healthier than the females because they are in short supply and therefore conduct in more matings (Eusociality). This suggests haploidy does not predispose a species to eusociality as much as diploidy does. It is inferred from this that the evolution of eusociality from haploidy must mean skewing of the shake up ratio towards females without them losing their fitness. Current theories of how this occurs come from the partially bivoltine insects such as the Hallicitine bees and the Sphecid wasps.

The evolutionary stability of eusociality is explained by the superorganism theory because it means that yet reproductive individuals are counted as individuals and unfruitful members of the family are considered extensions if the reproductive parent (Eusociality). This theory holds up if the workers are truly sterile and not just repressed. If they are sterile, they provide for their parents, and their genes are express through them.

Termites (order Isoptera) are also eusocial insect


Among the arthropods and crustaceans there is also evidence of eusociality: it is seen in several species of the hr synalpheid pistol shrimp species which depend on sponges for survival, live eusocially, with a single breeding female and many male defenders gird with snapping claws (Bees; Eusociality).

Castes are not fixed, and the workers remain totipotent and have the electromotive force to become a queen if the queen shrimp is removed.

s, simply they exhibit diploidy so the mechanism of evolution of eusociality in this species is mysterious (Bees; Eusociality). Some species of aphids (order Hemiptera) are eusocial: they have a partially agamic mode of reproduction, with sterile soldier castes being of the same ringer as the reproducing females. Among animals, the naked mole of Africa and the Delicate Slender possum are eusocial, and some canids are in that only the alpha male and female breed, the other members of the pack being repressed, though not sterile. Naked mole rats live in thickening underground tunnel networks, with animals in the same nest nearly related, and
