In many climates, a small decrease in the duration of uterine retention of eggs would not allow the female to produce a second clutch within the same season; and thus, would not reduce the fecundity disadvantage of viviparity. The female lays her eggs with exposure to the external environment instead of retaining them internally. This is especially true in cold weather. Create new account. What is the ⦠The phenomenon ranges from ovoviviparity (eggs deposited at an advanced stage of embryonic development; larva emerges immediately after deposition), through viviparity (larva hatches inside female before deposition) to pupiparity (offspring deposited as pupa). b. Vertebrate Zoology (BI2EV45) Uploaded by. Advantages of vivipary over ovipary ... Viviparity (give birth to live young) is good because the embryo can develop inside the mother where temperatures and nutrients are stable, thus enabling the young a greater chance to survive.

Two hypotheses have prevailed to explain the evolution of viviparity in reptiles: the first proposed that viviparity evolved in response to cold-climates because the possibility of pregnant females to thermoregulate at higher temperatures than embryos could experience in a nest in nature. 1 Answer. Most of the mammals, a few reptiles, and cartilaginous fish are viviparous.

Mothers can only carry and provide for a limited number of young. Humans reproduce via ⦠The transition from oviparity (egg laying) to viviparity (live bearing) is a major evolutionary shift in life history with many potential consequences for the morphology, physiology, behavior, and ecology of an organism (Shine and Bull 1979; Guillette 1993; Blackburn 2006; Thompson and Blackburn 2006; Thompson and Speake 2006).The evolution of viviparity may have disadvantages … … Ovoviviparity (offspring develops in ⦠A "difference between" reference site.

Most insects produce eggs but some, such as aphids, are viviparous and give birth to live young. These new data suggest the advantages of superfoetative viviparity for a small bodied fish in a 318 Myr old species- and predator-rich marine bay. In viviparity the young are born alive. However, viviparity may also allow increased control of nutrient transfer, such that mothers … If viviparious young can be nourished longer than oviparious young, then they may be larger and more capable of fending for themselves.
