Turtle origins: insights from phylogenetic retrofitting and molecular scaffolds.

abstract：:Reproduction entails costs, and disentangling the relative importance of each stage of the reproductive cycle may be important to assess the costs and benefits of different reproductive strategies. We studied the early costs of reproduction in oviparous and viviparous lizard females of the bimodal reproductive species...
