Internal fertilization is universal in chondrichthyan fishes and, as such, requires a suite of biological activities, including behavioral, morphological, and physiological mechanisms, to ensure successful copulation and fertilization. This volume correlates available data and ideas concerning the development, reproductive morphology, function, and phylogeny of chondrichthyan fishes. Coverage includes oogenesis, spermatogenesis, gestation, regulation of reproductive tract function, sperm storage, nutrient provision, placentation, and phylogeny. It also reviews and considers the idea that yolk sac viviparity is the plesiomorphic state rather than oviparity.

  • Exploring Genome’s Junkyard
    Subir Ranjan Kundu
    Exploring Genome’s Junkyard: In the Labyrinth of Evolution narrates the progress of biological evolution, beginning with the conceptual introspection of gene and continuing with the contemporary understanding of the structural and function aspects of the human genome. Recent advances in human genome research have led scientists to the term 'biological dark matter,' which refers...
  • European Hair, Eye, and Skin Color
    Peter Frost
    Europeans, especially those from northern and eastern Europe, are unique in having diverse hair and eye colors and a skin almost as pale as an albino’s. Those colors are not only brighter than the original black and brown but also 'purer'-they lie within thin slices of the visible spectrum. Overall, that color scheme is more developed in women, who naturally have a higher incid...

  • When Evolution Stops
    Armando Simon
    Evolution is a fact. The evidence for it is simply overwhelming. However, the original mechanism that generates the evolutionary process, as first put forth simultaneously by Charles Darwin and Alfred R. Wallace and which became known as Natural Selection, has now been seen to be too simplistic by some scientists aside from the hard-core neo-Darwinists who insist that nothing w...
