Humans quickly detect the presence of evolutionary threats through visual perception. Many theorists have considered humans to be predisposed to respond to both snakes and spiders as evolutionarily fear-relevant stimuli.

Pulmonoscopy is a practical diagnostic tool for investigating respiratory diseases in snakes. Two different approaches exist for pulmonoscopy, tracheal and transcutaneous. The access to the proximal or distal lung is limited by the length and diameter of the endoscope when using the tracheal approach.

Summary1. Current theories of ophidian evolution suggest that the snakes have been derived either from aquatic, above‐ground terrestrial, or burrowing ancestors. It is generally supposed that the ancestors of snakes, irrespective of their habits, were closely related to the platynotid lizards.

Effects of Snake Venoms on Snakes
Copeia, 1946IN 1931 I started a series of experiments on snake venoms in order to procure comparative data on the effects of venoms on various species of snakes. The war brought the work to a standstill in 1941, after I had concluded 58 experiments. Although the small number of experiments does not permit definite conclusions to be drawn, the work is now ...
