viviparity

The case of flowering plants stands by itself, for although they illustrate a kind of viviparity, the seed being embryos, an individual plant may have a large number of flowers and therefore a huge family.

They might have evolved viviparity, but I personally favour the idea that they were still oviparous and that females laid eggs in terrestrial nests.

Agamines are a really interesting group in terms of adaptation: we have scansorial, arenicolous and saxicolous species, the evolution of viviparity, and morphological transitions such as external ear loss.

As is seen in other squamate groups that have invaded cool, elevated places, toad-heads have evolved viviparity: this is present in just six Chinese species.

It has been suggested that the viviparity of the mangrove is a survival of a very remote period in the development of the earth — that a mangrove swamp represents an age when the earth was enveloped in clouds and mist; and that with the gradual decrease in tepid aqueous vapour the viviparous habit, then almost universal, was lost, except in the case of this plant.

Now there are many different methods of parental care which secure the safety of the young, and one of these is called viviparity.

There are only a few offspring at a time, and, although there are exceptional cases like the summer green-flies, which are very prolific though viviparous, the general rule is that viviparity is associated with a very small family.
