Carnivorans evolved out of members of the paraphyletic family Miacidae ( miacids ).

Carnivorans evolved from miacoids about 55 million years ago during the late Paleocene.

By the mid Oligocene, Creodonts supplanted both the Mesonychids, and giant flightless predatory birds entirely in North America, Eurasia and Africa, and in turn, competed with their own relatives, the Carnivorans.

Carnivorans tend to produce a single litter annually, but some produce multiple litters a year, and larger carnivorans, like bears, have gaps of 2 – 3 years between litters.

Carnivorans are the most diverse in size of any mammalian order, ranging from the least weasel ( Mustela nivalis ), at as little as and, to the polar bear ( Ursus maritimus ), which can weigh up to, to the southern elephant seal ( Mirounga leonina ), whose adult males weigh up to and measure up to in length.

Carnivorans have teeth, claws, and binocular vision adapted for catching and eating other animals.

Carnivorans are primarily terrestrial and usually have strong sharp claws, with never fewer than four toes on each foot, and well-developed, prominent canine teeth, cheek teeth ( premolars and molars ) that generally have cutting edges.

Carnivorans have six incisors and two conical canines in each jaw.

Carnivorans have either four or five digits on each foot, with the first digit on the forepaws, also known as the dew claw, being vestigial in most species and absent in some.

Carnivorans include carnivores, omnivores, and even a few primarily herbivorous species, such as the giant panda.

: For the most part, Dixon assumes that Carnivorans have either gone extinct, or have been forced into peripheral niches like the Creodonts were in the Oligocene.

Other prey species of that time evolved more rapidly ( like M. malei, the presumed ancestor of today's Tundra Vole M. oeconomus ), while yet again others seem to have gone entirely extinct without leaving any living descendants – for example Pliomys lenki, which apparently fell victim to the Weichselian glaciation about 100. 000 years ago.

Hybridization with the subspecies that evolved southwestwards of its range, S. c. massaicus, has apparently been prevented from occurring on a significant scale by ecological separation, the Somali Ostrich preferring bushland where it browses middle-height vegetation for food while the Masai Ostrich is, like the other subspecies, a grazing bird of the open savanna and miombo habitat.

Pencil, from Old French pincel, a small paintbrush, from Latin a " little tail " ( see penis — pincellus is Latin from the post-classical period ) is an artist's fine brush of camel hair, also used for writing before modern lead or chalk pencils ; the meaning of " graphite writing implement " apparently evolved late in the 16th century.

The Passeriformes apparently evolved out of a fairly close-knit clade of " near passerines " which contains such birds as the Piciformes and Coraciiformes.

The sarcopterygians apparently took two different lines of descent and are accordingly separated into two major groups: the Dipnomorpha ( including the Dipnoi or lungfishes ) and the Tetrapodomorpha ( which include extinct lines of lobe-finned fishes that evolved into the Tetrapoda ).

Its inhabitants have apparently evolved their own independent society with almost no legal contact with the outside world.

The addition of the Windows Key to keyboards may have been part of the reason why most current games have evolved their control schemes, and most first person shooters generally use the mouse in conjunction with a " Half-Life " style of control ( W, A, S, D, Space, Shift, Ctrl ) named apparently because it may have been the first widespread game to popularize such an interface, and because usage of the Alt button would nowadays heighten the risk of accidentally pressing the Windows Key.

Curiously, the same mechanism apparently evolved independently in the extinct Cretaceous-age Hesperornithiformes, which are totally unrelated birds.

This difference apparently evolved in parallel with the differences in frequency range of hearing and in frequency resolution between mammals and non-mammalian vertebrates.

As these are separated by different behaviour and ecological requirements and have not evolved fertilisation barriers, the two European species can nonetheless produce apparently fertile and viable hybrids.

This is quite unusual among different species, and apparently is because the Mallard evolved very rapidly and recently, during the Late Pleistocene.

That the genus Tympanuchus apparently evolved rapidly and therefore has high morphological but low genetic distinctness between taxa further complicates research.

In conclusion, of the 3 basic morphotypes found in this genus, one ( bright, long-tailed, large ) is plesiomorphic, another ( large, short-tailed, drab ) apparently only evolved once, and the third ( the small slope-inhabiting forms ) are convergent in morphology.

The Tunicata apparently evolved in the early Cambrian period.

They apparently evolved from " primordial soup ", and over the course of millions of years, turned into a space-faring species.

Even many of Darwin's original supporters ( such as Alfred Russel Wallace and Charles Lyell ) balked at the idea that human beings could have evolved their apparently boundless mental capacities and moral sensibilities through natural selection.

More difficult for Darwin were highly evolved and complicated features that conveyed apparently no adaptive advantage to the organism.

The earliest known circles were apparently erected around five thousand years ago during the Neolithic period and may have evolved from earlier burial mounds which often covered timber or stone mortuary houses.

The descendants of the Aurorans, or Mycogenians, never forgot Aurora, but they apparently evolved to the point where they were indistinguishable from Settlers.

Root nodules apparently have evolved three times within the Fabaceae but are rare outside that family.

The Vancouver Island marmot, as its name suggests, is geographically restricted to Vancouver Island, and apparently evolved rapidly since retreat of the Cordilleran glaciation some 10, 000 years before present.

The term " Abhuman " was used by Hodgson in The Night Land to name ( apparently ) several different species of intelligent beings evolved from humans who interbred with alien species or adapted to changed environmental conditions and were seen as decayed or malign by those living inside the Last Redoubt, who preserved artificially ( to an unspecified extent ) their human characteristics, though they were not fit for the new environmental conditions.

As late as 1861, a traveler in North Carolina saw dancers dressed in costumes that included horned headdresses and cow tails and heard music provided by a sheepskin-covered " gumbo box ," apparently a frame drum ; triangles and jawbones furnished the auxiliary percussion.

Dabbalemi initiated diplomatic exchanges with sultans in North Africa and apparently arranged for the establishment of a special hostel in Cairo to facilitate pilgrimages to Mecca.

Finally, the PRC exploded its first atomic bomb in October 1964 and subsequently refused to give North Korea any nuclear weapons of its own, apparently fearing that Kim was too likely to use them in his quest to reunify the peninsula.

Though Seoul completed a " Peace Dam " on the Pukhan River to counteract the potential threat of Pyongyang's dam project before the 1988 Olympics, the North Korean project apparently still was in its initial stages of construction in 1990.

In 1199 he captured the important castle of Mold and was apparently using the title " prince of the whole of North Wales " ().

In late August 1989, while working as an engineer on the jack-up barge GSF Galveston Key in the North Sea, Chris Gibson and another witness saw an unfamiliar isosceles triangle-shaped delta aircraft, apparently refueling from a Boeing KC-135 Stratotanker and accompanied by a pair of F-111 fighter-bombers.

This group apparently died out and were succeeded by several other groups migrating from continental North America.

The diverse range of buildings of Venturi's early career offered surprising alternatives to then current architectural practice, with " impure " forms ( such as the North Penn Visiting Nurses Headquarters ), apparently casual asymmetries ( as at the Vanna Venturi House ), and pop-style supergraphics and geometries ( for instance, the Lieb House ).

The flightless subfamily Mancallinae, which was apparently restricted to the Pacific coast of southern North America and became extinct in the Early Pleistocene, is sometimes includes in the family Alcidae under some definitions.

He derived his surname apparently from being a native of Stobi in North Macedonia.

In November 1987, North Korean operatives apparently destroyed Korean Airlines Flight 858, which exploded in Myanmar ( Burma ), The North Korea government has since renounced its sponsorship of terrorism .”

The satellite failed, but the missile apparently flew without significant problems, therefore it is North Korea's longest-ranged operational missile with its 2, 500 km maximum range.

Starting in late August 2008, North Korea allegedly resumed its nuclear activities at the Yongbyon nuclear facility, apparently moving equipment and nuclear supplies back onto the facility grounds.

Bailey, known as " Brit ," moved his family from North Carolina to Kentucky and apparently served in the legislature of that state.

The Mallards of North America, for example, are apparently mostly derived from some males which arrived from Siberia, settled down, and mated with American Black Duck ancestors.
