They are the only group of living mammals that lay eggs, rather than bearing live young. The extant monotreme species are the platypus and the four species of echidnas. Monotremes are typified by structural differences in their brains, jaws, digestive tract, reproductive tract, and other body parts, compared to the more common mammalian types.
Also featured in that project was Steve Hillage (on summer holiday from university), who had like the others been a member of the pre-Egg band Uriel.

Animals, including mammals, produce gametes (sperm and egg) through meiosis in gonads (testicles in males and ovaries in females). Sperm are produced by the process of spermatogenesis and eggs are produced by oogenesis. These processes are outlined in the article gametogenesis.
Earlier this month, bodegas began selling eggs in groups of three for $3 after customers balked at buying a dozen of them for about $12, according to local media reports.
Eusociality was then discovered in a group of chordates, the mole-rats. Further research distinguished another possibly important criterion for eusociality, "the point of no return". This is characterized by having individuals fixed into one behavioral group, usually before reproductive maturity.
