They don’t oppose the idea that the stroke of meteorite upon the planet and its responding impacts in the long run to kill dinosaurs, but further elaborate it. They elucidate that among mammals like human beings and other creatures gender is genetically determined in an equal ratio. Whereas, in some cold blooded animals like fish and reptiles, sex determination is based on condition of temperature. If these conditions remain ideal, the male/female ratio can be 1:1. However, changing conditions of temperature may cause a slant towards either of the two genders. Consequently, a slant is towards males may direct a turn down in overall population. They further explain that this mechanism of gender classification is being even presently observed among the crocodiles which are basically alike dinosaurs in terms of both biology and physiology. Thus the idea of dinosaur this way is strengthened.In order to demonstrate the impacts of gender ratio on overall population, the theorists utilized the idea of the “Evolution of Y Chromosome” in mankind and linked it with mathematical techniques. Moreover, even better representation is being proposed toward the search of climatic change impacts upon dinosaurs and their eggs in varied types and sizes. The researchers believe that there was a sudden but extended turn in the climate and was not coped y the dinosaurs and they had an exceeded number of males which ultimately resulted into their extinction. (Miller et al.This theory suggests that dinosaurs were unable to keep up with the many changes that were occurring on the earth toward the end of the Cretaceous period. During the dinosaur age, the earth was very different from the earth today. The climate was generally warmer than it is in the same. Extinction of Dinosaurs.
