Sex allocation is an important field in evolutionary biology, both historically and currently. However, while sex
allocation theory has successfully predicted sex ratio bias in some taxa, most notably parasitic wasps, vertebrates
are notorious for their poor fit to theoretical models. We argue that this arises from the use of very complex
model systems to test relatively simple theoretical models. We further argue that squamate reptiles - lizards and
snakes - have unduly been neglected in sex allocation studies and in fact may conform more readily to the
underlying assumptions of existing theoretical models than many other vertebrates. We provide a five-point
argument in favor of the use of squamates as model systems in sex allocation based on their diversity in sex
determining mechanisms, life history biology, and ease of experimental manipulations.
