 runners found themselves in a predica- ment. Their only recourse was migra tion, and that some of the species sue ceeded in this is fully established by the presence of their descendants in the tropics today.
 But many species were virtually trapped in these peninsulas, and it is not only possible. but highly probable, that these species either succumbed to the advancing cold. or were rapidly modified to meet the exigencies of the new conditions. In this category I place the ancestors of man.
 As preliminary proof of the presence of mans ancestors in these peninsulas of southern Europe or Asia, whence they emigrated from the north, pr. Wortman. in the Journal of Science. will first advance the theory that the origin of most forms of higher mann malian life was in the north. in the re- zion now known as the North Pole, now frigid, but in the middle geological stages inhabited by a rich tropical veg citation and enjoying a tropical climate.
 It is his theory that the oncoming of the glacial epoch gradually changed the climate Of the Arctic circle from tropical to frigid. that tropical condi- tions slowly retreated southward over both America and Europe and Asia, carrying with them tropical vegetation and animal life. until the present wide distribution of plants and animals was attained. As this southward retreat continued, notifications of both the tropical vegetation and animal life re- mained in the temperate attitudes. giv- ing rise to the vast number of d 'fferent inhabit the earth today.
 The question asked by opponents of the evolution theory of Charles Darwin as to why man did not originate on both continents if he came from the ape at all, Dr. Wortman answers in the Journal of Science. He says that when the retreat from the Arctic circle began two main streams of plant and animal life came down over the eastern and western hemispheres.
 In America the monkeys never de- American type, small, long tailed species, with a very low order of intel lect. On the eastern hemisphere, how ever, there early began the development of the monkey species up to the present higher apes of Africa and Asia. This, he states. is a fact proved by the fossil remains of monkeys in both hemis- pheres.
 With the advance of the cold epoch. and the consequent retreat of tropical plant and animal life southward, th4. treated through the forest ranges of Mexico into South America, where they are alone found now on this continent. In the eastern hemisphere, however, a number of interesting things took place. some of which left the higher apes in their present localities, and others brought about the enforced evo- lution of man.
 Retreating with their favorite forest environment and food southward, these more highly developed apes came to be finally distributed all along the south ern coast of Europe. in Spain. France. Italy and Greece and along the south ern shores of Asia, in India especially
 With them were numerous other the final stages of the vast tropical vegetation that originally had inhab- ited the Arctic circle. their own original home. The cold was gradually but steadily advancing from the north and the only end to this was the final dis appearance of tropical vegetation.
 Trapped in these peninsula areas, where they could not escape, except to invite extinction by facing the un- known area of cold to the north or the sea to the south, the alternatives wera presented of either succumbing to tht changed environment, or modifying themselves to fit the new conditions In all likelihood numerous members oi | these highly developed apes succumbed | and became extinct. Others, few survived, through superior menta i equipment, and it is at this time and l in this way that man came upon the scene"
 The presence of such higher apes as the gorilla. chimpanzee, etc, in Asi; and Africa today Dr. Wortman eX plains. He says that a few lant bridges existed at that time, as now between Europe and Asia and Africa and that it was southward over thes: approaches to the present trOpica zones that the ancestors of these ape. escaped.
 Trapped in these peninsulas it is Dr Wortmans contention that a quick an, unprecedented change came over tn apes that just preceded man, and tha instantly awoke their intellect an, spanned the space between the highes apes and the lowest man. The frs change came in the difference in tn
