Re: Sheesh

<<So, let's ACTUALLY look at the situation, and perhaps ask the
evolutionarily interesting question:>>

Why have no birds, or indeed -as far as is known- archosaurs (sensu sort of
traditional) never got around to giving birth to live young (sensu any way
anybody chooses)?  Bearing that latter proviso in mind, some sharks, fish
(sensu very loose indeed), frogs, reptiles of various persausions (or
sauropsoids), scorpions...  Various lineages have manged this, but
archosaurs seem uninterested in such experiments.

My suspicion is that the hard and potentially sharp eggshell shards may be a
discouragement, but it's no more than a suspicion.
