William Diller Matthew
William Diller Matthew FRS (February 19, 1871 – September 24, 1930) was a vertebrate paleontologist who worked primarily on mammal fossils, although he also published a few early papers on mineralogy, petrological geology, one on botany, one on trilobites, and he described Tetraceratops insignis, which was much later suggested to be the oldest known (Early Permian) therapsid.
Matthew was born in Saint John, New Brunswick, the son of George Frederic Matthew and Katherine (Diller) Matthew. His father was an amateur geologist and paleontologist who instilled his son with an abiding interest in the earth sciences. Matthew received an A.B. at the University of New Brunswick in 1889 and then earned his Ph.D. at Columbia University in 1894.
Asia hypothesis 
Matthew believed that the first humans had originated in Asia, he visited Asia by taking part in the Central Asiatic expeditions. Matthew was also well known for his deeply influential 1915 article “Climate and evolution”, Matthews theory was that climate change was how organisms came to live where we find them today in opposition to the theory of continental drift. His basic premise was that cyclical changes in global climate along with the prevailing tendency for mammals to disperse from north to south account for the odd geographic patterns of living mammals, he believed that humans and many other groups of modern mammals first evolved in the northern areas of the globe, especially central Asia because of the shifting climatic circumstances, Matthew firmly placed hominid origins in central Asia as he claimed that the high plateaux of Tibet was the forcing ground of mammalian evolution.
