Premise: The Sahara Desert ant ("Cataglyphis bicolor") is a desert-dwelling ant of the genus "Cataglyphis". It inhabits the Sahara Desert and is one of the most heat tolerant animals known to date. However, there are at least four other species of "Cataglyphis" living in the Sahara desert, for example "C. bombycina", "C. savignyi", "C. mauritanicus" and "C. fortis".
Hypothesis: The ants are not heat tolerant
