Pathologic changes can only be recognized and diagnosed with a good understanding and knowledge of reptile anatomy and pathophysiology.
After discarding a burn in of 50% we filtered the output trees using PAUP* and a set of "soft" backbone constraints (polytomies representing uncertain parts of the topology), so that all trees were consistent with current knowledge of reptile phylogeny and that subtrees that need to be monophyletic for the calibration points were not violated.
Knowledge of spermiogenesis in reptiles, especially in lizards, is very limited.

Similarly, he built on existing knowledge that a group of reptiles were ancestors of mammals with fossil evidence to show how this happened: the reptilian jaw morphed into part of a mammalian inner ear.
This reexamination has improved the knowledge and understanding of reptile evolution and classification, although it has made the latter more complex and less stable.
The Shasta County expeditions were certainly important in terms of expanding our knowledge of the Triassic marine reptiles of California, but the people encountered and places visited, particularly in the case of the 1902 expedition, were fascinating in their own right.
In addition, the Egyptians had a great interest in, and knowledge of, most species of mammals, birds, reptiles, and fish in their environment.
Herpetology (the study of reptiles and amphibians) was his specialty, and he skilfully conveyed his advice and knowledge in his books and broadcasts.
