when did the first mammal appear on earth
late Carboniferous period
Evolution of mammals The evolution of mammals has passed through many stages since the first appearance of their synapsid ancestors in the late Carboniferous period. The most ancestral forms in the class Mammalia are the egg-laying mammals in the subclass Prototheria. This class first started out as something close to the platypus and evolved to modern day mammals. By the mid-Triassic, there were many synapsid species that looked like mammals. The lineage leading to today's mammals split up in the Jurassic; synapsids from this period include "Dryolestes", more closely related to extant placentals and marsupials than to monotremes, as well

widespread than many other countries. A 2014 study revealed Germans (28%) were the most likely of all nations surveyed to have been nude at a beach. The largest skinny dip was achieved during an event organized by Deirdre Featherstone(Ireland). The official figure is 2,505 women and was achieved on 9 June 2018 in Wicklow, Ireland. The event was organized to raise awareness on breast cancer and to raise funds for Aoibheann’s Pink Tie , a National Children’s Cancer Charity. Nude swimming was a common subject of Old Masters – painters from before the 1800s – and Romantic oil paintings, usually

It was discovered and named after Dr. John W. Huffman. JWH-015 has been shown "in vitro" to be metabolised primarily by hydroxylation and N-dealkylation, and also by epoxidation of the naphthalene ring, similar to the metabolic pathways seen for other aminoalkylindole cannabinoids such as WIN 55,212-2. Epoxidation of polycyclic aromatic hydrocarbons (see for example benzo(a)pyrene toxicity) can produce carcinogenic metabolites, although there is no evidence to show that JWH-015 or other aminoalkylindole cannabinoids are actually carcinogenic "in vivo". A study published in the British Journal of Cancer shows that JWH-015 may signal certain cancers to shrink through a process called

Officer for the whole of Kathiawad under the British Political Agency in 1918. He hailed Mahatma Gandhi on his 50th birthday as the Hermit of Gujarat in a memorable poem which he composed in 1919. When Mahatma Gandhi launched the Non-Cooperation Movement, Nanala Kavi responded to it by resigning his Government post in 1921, whereafter he lived in Ahmedabad, wholly devoted to writing. He breathed his last on 9 January 1946 in adverse pecuniary as a gifted poet of our time. A romantic idealist in the tradition of the English romantic poets of the 19th century, Nanalal was a lyrical

In order to catch up with the “grass is greener” cities and even emulate the “rising stars”, each delivery team has been given a set of performance measures, under each Aim, as follows: Actions: as part of an Enterprise and Innovation Strategy for Sunderland, entrepreneurship development programmes will be put on the city’s educational curricula, and provide better support for startups and small and medium-sized

appeared in the 2005 "Black Jack: Two Doctors of Darkness" movie. A character named Rock (but of a different appearance and personality) also appeared in the 1980 animated "Phoenix 2772". In addition, Rock's character ("sans" sunglasses) was used to portray the young King Bimbisara in Tezuka's sprawling "Buddha". Rock has appeared in more than 60 different manga and animated works, in the live action "Vampire" TV series, and in the "" video game. Rock (manga) Rock (known in some series as Rokuro Makube a.k.a. Rock Macbeth or ) is a recurrent major character in most of Osamu Tezuka's manga series,

Due to a redefinition of the boundary between the Neogene and Quaternary periods, MN 17 is now in fact considered a Quaternary biozone.

European land mammal age The European Land Mammal Mega Zones (abbreviation: ELMMZ, more commonly known as European land mammal ages or ELMA) are zones in rock layers that have a specific assemblage of fossils (biozones) based on occurrences of fossil assemblages of European land mammals. These biozones cover most of the Neogene and Paleogene systems (i.e. rock layers which are 65.5 to 2.588 million years old). In cases when fossils of mammals are abundant, stratigraphers and paleontologists can use these biozones as a more practical regional alternative to the stages of the official ICS geologic timescale.

Saint Bathans mammal The Saint Bathans mammal is a currently unnamed extinct mammal from the Miocene of New Zealand. A member of the Saint Bathans Fauna, it is notable for being a late surviving "archaic" mammal species, neither a placental or marsupial, as well as for providing evidence that terrestrial mammals did in fact once live in Zealandia, in contrast with modern New Zealand, where bats are the only mammals in otherwise bird-dominated terrestrial faunas. The Saint Bathans mammal is currently represented by two specimens, MNZ S.40958 and MNZ S.42214, composed of a lower jaw fragment and a femur respectively.

native to the colony on Willow-Wane who believes he can find new inspiration for his poetry by coming in contact with the physically repulsive humans, an intelligent mammal race that is unlike the insectoid thranx. Desvendapur's aspirations lead him to a secret thranx colony in the Amazon Basin on Earth where he meets a petty human thief turned murderer, Cheelo Montoya. Desvendapur is fascinated by the first native human he comes across so, with great resistance on the part of Montoya, chooses to follow the human, using him as the basis of a series of poems.

and then spread to the rest of the world. His views have been compared to the paleontologist Florentino Ameghino who believed that humanity had originated on the banks of Río de la Plata. Goodman claims that the fossils in North America are "twice as old as the oldest fully modern skull from europe". In his work he attempted to show that the American Indians were not only the first Americans but were the first humans on earth. Goodman allows that hominids did appear in Asia and Africa, though homo sapiens are completely American in origin according to his theory. Goodman's
