Snakes comprise nearly 4,000 extant species found on all major
continents except Antarctica. Morphologically and ecologically diverse,
they include burrowing, arboreal, and marine forms, feeding on prey
ranging from insects to large mammals. Snakes are strikingly different
from their closest lizard relatives, and their origins and early
diversification have long challenged and enthused evolutionary
biologists. The origin and early evolution of snakes is a broad,
interdisciplinary topic for which experts in palaeontology, ecology,
physiology, embryology, phylogenetics, and molecular biology have made
important contributions. The last 25 years has seen a surge of interest,
resulting partly from new fossil material, but also from new techniques
in molecular and systematic biology. This volume summarises and
discusses the state of our knowledge, approaches, data, and ongoing
debates. It provides reviews, syntheses, new data and perspectives on a
wide range of topics relevant to students and researchers in
evolutionary biology, neontology, and palaeontology.
