    Darwin's finds also included at least three other giant ground sloths, an extinct form of horse, and a protective carapace of small bony scutes fitted closely together, remnant from some big beast.   Eastern equine encephalitis virus (EEEV) is an important veterinary and human pathogen belonging to one of seven antigenic complexes in the Alphavirus genus, family Togaviridae ().Isolated throughout the Americas, EEEV is classified as the only species in the eastern equine encephalitis (EEE) complex (9, 10), which was originally divided into North and South American varieties based on Cited by:

When studying the history of Central America one must first clarify just what Central America is.

Evolutionary relationships of some South American ground tyrants. [William John Smith; François Vuilleumier].

Phylogenetic relationships within the genus Cinclodes, a group of South American furnariids, were studied using complete sequences of the mitochondrial genes COII and ND3. The ground tyrants are a genus of passerine birds belonging to the tyrant flycatcher family Tyrannidae. There are about 13 different species.

They are ground-dwelling birds which inhabit open country in South America, particularly the Andes and Patagonia. Several southern species are migratory, moving northward for the winter. Ground tyrants feed on insects and other invertebrates, mainly by picking them from the ground Class: Aves.

Phylogeny is the evolutionary relationship between organisms. The phylogeny of an organism reflects the evolutionary branch that led up to the organism. This is a relatively slow way of walking since most of the foot comes in contact with the ground.

The largest birds living today, the African ostrich and the Australian emu, are ratites. There are ten more living ratite species: two species of South American rhea, five species of New Zealand kiwi and three cassowary species, found in Australia and adjacent islands.

Convergent evolution is the mechanism for this occurrence. Characid fishes first evolved where the fossils are found but were carried to South America and Africa by birds.

Characid fishes arose prior to the separation of the African and South American continents.This is a book about evolution, about a failed evolutionary revolution, and in a layering deftly handled by one of the new queens of fairy tale play, the text itself also evolves and the language is used for revolt: "A long time ago, long before man walked upright, the earth was filled with water.

It was a 4/5. About million years ago, toward the middle of the Cretaceous period, some South American crocodiles had begun to imitate their dinosaur cousins by evolving to enormous sizes.

The king of the Cretaceous crocodiles was the enormous Sarcosuchus, dubbed "SuperCroc" by the media, which measured about 40 feet long from head to tail and weighed.
