Only after roughly three weeks do they begin to look dissimilar enough to distinguish them from one another. The similarities in the skull can still be seen even after many members mature. ]]> 2017-05-30 12:37:01 UTC https://padlet.com/cb138/7hjd629wihzy/wish/174396708 cb138 https://padlet.com/cb138/7hjd629wihzy/wish/174398742 This phylogenetic tree shows how the different lower classifications of the order Squamata are related to each other and how there are distinct sub-groups within the order.]]> 2017-05-30 12:47:15 UTC https://padlet.com/cb138/7hjd629wihzy/wish/174398742 cb138 https://padlet.com/cb138/7hjd629wihzy/wish/174601773 The clade Toxicofera encompasses all venomous reptiles and some non-venomous, a group that has evolved separately from the rest of the order Squamata. These organisms have evolved venom glands in the upper or lower jaw that allow those organisms to be better predators, using their venom to paralyze, poison, or otherwise incapacitate their prey. Venom genes in this clade create large multigene families, and are coded to form different proteins, resulting in different levels of toxicity and physiological effects in the venom.]]> 2017-05-31 12:08:14 UTC https://padlet.com/cb138/7hjd629wihzy/wish/174601773 cb138 https://padlet.com/cb138/7hjd629wihzy/wish/174794966 2017-06-01 12:08:49 UTC https://padlet.com/cb138/7hjd629wihzy/wish/174794966 cb138 https://padlet.com/cb138/7hjd629wihzy/wish/174795532 In a study of the lower classifications Scincomorpha and Iguanina, the number of repetitive DNA units varied from one or several dozens in Iguanina to several hundred in Scincomorpha.
