The problem with this theory is that the initial shift from wolf-like to dog-like traits could only have happened very slowly. Wolves are relatively uniform in appearance, so the odds of a mutation appearing randomly in a captive population are small. It would have taken many thousands or even millions of years to get much diversity. Yet fossil evidence shows that dogs appeared not all that long ago. If it's true that dogs have existed for only about 15,000 years, this is a blink of the eye in evolutionary terms. DNA evidence indicates that dogs may have begun to split with wolves as many as 100,000 years ago, but this is still relatively recent. Yet in dogs we see some of the most extreme physical diversity of any mammalian species. There is more variation in size, color, coat texture and other aspects of appearance within dogs than there is among all other members of the canid family. Recent publications, such as the controversial book "Dogs: A Startling New Understanding of Canine Origin, Behavior, & Evolution," by Raymond and Lorna Coppinger, present an alternative theory for the way that dogs evolved from wolves.|Efficient and adaptive computer vision systems have been proposed to make computer vision tasks, such as image classification and object detection, optimized for embedded or mobile devices. These solutions, quite recent in their origin, focus on optimizing the model (a deep neural network, DNN) or the system by designing an adaptive system with approximation knobs. In spite of several recent efforts, we show that existing solutions suffer from two major drawbacks. First, the system does not consider energy consumption of the models while making a decision on which model to run. Second, the evaluation does not consider the practical scenario of contention on the device, due to other co-resident workloads. In this work, we propose an efficient and adaptive video object detection system - Virtuoso, which is jointly optimized for accuracy, energy efficiency, and latency. Underlying Virtuoso is a multi-branch execution kernel that is capable of running at different operating points in the accuracy-energy-latency axes, and a lightweight runtime scheduler to select the best fit execution branch to satisfy the user requirement. What is their history together? While the two countries history stretches back centuries, present tensions effectively originate when the first independent Ukrainian state was declared in Kiev in 1917 following the collapse of the Russian and Austro-Hungarian empires towards the end of World War I. That independence was short lived though as it was invaded by Poland. Fought over between forces loyal either to the czar or the newly-established Bolshevik government. It was eventually swallowed up into the Soviet Union in 1922 at a time when its economy was in tatters. When Ukranian farmers refused to join the collective farms being established under Joseph Stalin in the 1930s, he stamped his tyrannical rule by orchestrating mass executions and starved millions of people to death. Stalin also imported millions of Russians. Other citizens in the Soviet Union to the region to help rebuild the country. Ukraine eventually became independent in 1991 with more than 90 percent voting to break away from the collapsing Soviet Union. But Russia has continued to meddle in the country’s affairs, most notably in the Ukraine’s 2004 presidential election when the Kremlin backed the pro-Russian candidate Viktor Yanukovych. The Crimea has become a flashpoint between the two countries. The move is still deeply unpopular with many Russians who still see the region as theirs. What happened in Crimea? On November 25, 2018 Russia captured three Ukrainian naval vessels which were sailing off the coast of Crimea. Russia opened fire, before special forces stormed the vessels. Ukraine said it was a Russian "act of aggression". Moscow said the ships had illegally entered its waters in the hotly-contested Kerch Strait. totoaba
