• extinct
  • When teeth of the extinct gondwanathere mammals were first discovered in Argentina in the 1980s, they were thought to be related to xenarthrans, leading to renewed attention for the hypothesis that xenarthrans are not placentals. (wikipedia.org)
  • Bonaparte argued against George Gaylord Simpson's 1931 view that xenarthrans derive from the Tertiary Palaeanodonta of North America, and instead suggested that xenarthrans, and perhaps pangolins, split from eutherians (placentals and their extinct relatives) as early as the Early Cretaceous and derived from some early "pantothere" (a now-abandoned grouping of early mammals, including dryolestoids among others). (wikipedia.org)
  • It does not include extant mammals or recently extinct mammals. (wikipedia.org)
  • Excluding bats, nearly 90% of the mammals of the Caribbean faunal region have gone extinct since the late Pleistocene, including all the sloths and monkeys, the unique insectivore Nesophontes, two of four species of solenodon, and a variety of rodents including all giant hutias, leaving only a few hutia species extant. (wikipedia.org)
  • marsupials
  • Consequently, he suggested that they should be given a grouping separate from the other major groupings of mammals, for which terms had been introduced by Thomas Huxley: Eutheria (placentals) and Metatheria (marsupials). (wikipedia.org)
  • Australia is also home to the world's largest and most diverse selection of marsupials: mammals with a pouch in which they rear their young. (wikipedia.org)
  • It was intended to be a complete survey of the novel species of mammals, such as the marsupials, discovered in the colonies of Australia. (wikipedia.org)
  • Primates
  • A small percentage of the mammals are non-human primates, including the grivet, the rhesus macaque, and the crab-eating macaque, which are used in research for their similarity to humans. (wikipedia.org)
  • humans
  • Sexual selection in mammals started with Charles Darwin's observations concerning sexual selection, including sexual selection in humans, and in other mammals, consisting of male-male competition and mate choice that mold the development of future phenotypes in a population for a given species. (wikipedia.org)
  • fauna
  • A unique and diverse albeit phylogenetically restricted mammal fauna is known from the Caribbean region. (wikipedia.org)
  • The restricted, unbalanced nature of the Caribbean mammal fauna implies that rafting was part of the overall process. (wikipedia.org)
  • The Mahajanga Basin of northwestern Madagascar has produced a rich late Cretaceous fauna, including various dinosaurs and crocodyliforms as well as mammals, found by the team of David W. Krause since 1993. (wikipedia.org)
  • Birds
  • Gracius Broinowski's abandoned work, Birds and Mammals of Australia (1884), so closely imitated the plates that an injunction was threatened by its publisher. (wikipedia.org)

  • taxonomic
  • Paratheria is an obsolete term for a taxonomic group including the xenarthran mammals (sloths, anteaters, and armadillos) and various groups thought to be related to them. (wikipedia.org)

  • Mammals are the highest class of vertebrates and the female has mammary glands which secrete milk for the nourishment of young after birth. (australiazoo.com.au)
  • placentals
  • In 1910, William King Gregory reviewed the interrelationships of mammals and placed edentates among other placentals, though he gave "Paratheria" as an alternative name for his superorder Edentata, which included Xenarthra and tentatively Pholidota (pangolins), Tubulidentata (aardvarks), and the fossil Taeniodonta. (wikipedia.org)
  • agricultural
  • The new agricultural economies, based on domesticated mammals, caused "radical restructuring of human societies, worldwide alterations in biodiversity, and significant changes in the Earth's landforms and its atmosphere. (wikipedia.org)
  • earliest
  • Mammals such as horses and deer are among the earliest subjects of art, being found in the Upper Paleolithic cave paintings such as at Lascaux. (wikipedia.org)
  • animals
  • Mammals are one of the classes of vertebrate animals. (philadelphiazoo.org)
  • A major way that people relate to mammals (and some other animals) is by anthropomorphising them, ascribing human emotions and goals to them. (wikipedia.org)
  • Mammals serve a major role in science as experimental animals, both in fundamental biological research, such as in genetics, and in the development of new medicines, which must be tested exhaustively to demonstrate their safety. (wikipedia.org)
  • The mammals are such a widespread, varied and successful group of animals that Attenborough had previously devoted no fewer than five episodes of Life on Earth to them. (wikipedia.org)
  • males
  • A good example of intrasexual selection, in which males fight for dominance over a harem of females, is the elephant seal - large, oceangoing mammals of the genus Mirounga. (wikipedia.org)
  • Both species show extreme sexual dimorphism, possibly the largest of any mammal, with southern males typically five to six times heavier than the females. (wikipedia.org)
  • niches
  • The high diversity and endemicity of mammals is related to the many niches found in the tropical rain forest of Borneo and past Pleistocene events within the Sundaland region. (wikipedia.org)
  • ancestors
  • This led its discoverers to propose that the ancestors of tribosphenic mammals arose in the south (Gondwana), not, as generally assumed, in the north (Laurasia). (wikipedia.org)
  • live
  • In mammals, pregnancy is the period of reproduction during which a female carries one or more live offspring from implantation in the uterus through gestation. (wikipedia.org)
