Description. Diagram of a wolf skull with key features labelled. The Paleolithic dog was smaller than the Pleistocene wolf (Canis c.f. lupus)[1] and the extant grey wolf (Canis lupus), with a skull size that indicates a dog similar in size to the modern large dog breeds. The Paleolithic dog had a mean body mass of 36–37 kg (79–82 lb ...
The domestication of the dog was the process which led to the domestic dog. This included the dog's genetic divergence from the wolf, its domestication, and the emergence of the first dogs. Genetic studies suggest that all ancient and modern dogs share a common ancestry and descended from an ancient, now-extinct wolf population – or closely ...
Early Jazz: Its Roots and Musical Development, by Gunther Schuller, is a seminal study of jazz from its origins through the early 1930s, first published in 1968. [1] It has since been translated into five languages (Italian, French, Japanese, Portuguese and Spanish). [2] When it was published, it was the first volume of a projected two volume ...
539 Ma – present. The Phanerozoic Eon (Greek: period of well-displayed life) marks the appearance in the fossil record of abundant, shell-forming and/or trace-making organisms. It is subdivided into three eras, the Paleozoic, Mesozoic and Cenozoic, with major mass extinctions at division points.
The scientific question of within which larger group of animals birds evolved has traditionally been called the " origin of birds ". The present scientific consensus is that birds are a group of maniraptoran theropod dinosaurs that originated during the Mesozoic Era. A close relationship between birds and dinosaurs was first proposed in the ...
Morton was a crucial innovator in the evolution from the early jazz form known as ragtime to jazz piano, and could perform pieces in either style; in 1938, Morton made a series of recordings for the Library of Congress in which he demonstrated the difference between the two styles. Morton's solos, however, were still close to ragtime, and were ...
The dire wolf (Aenocyon dirus[10] / iːˈnɒsaɪ.ɒn ˈdaɪrəs /) is an extinct canine. The dire wolf lived in the Americas (with a possible single record also known from East Asia) during the Late Pleistocene and Early Holocene epochs (125,000–9,500 years ago). The species was named in 1858, four years after the first specimen had been found.
The Oligocene featured the expansion of grasslands which had led to many new species to evolve, including the first elephants, cats, dogs, marsupials and many other species still prevalent today. Many other species of plants evolved in this period too. A cooling period featuring seasonal rains was still in effect.
