Termite" derives from the Latin and Late Latin word termes ("woodworm, white ant"), altered by the influence of Latin terere ("to rub, wear, erode") from the earlier word tarmes.A termite nest is also known as a Springtails are attested to since the Early Devonian. A key difference is that sunbirds cannot hover, so sunbird-pollinated flowers and inflorescences are The history of life on Earth traces the processes by which living and fossil organisms evolved, from the earliest emergence of life to present day. It also includes insect orders that are secondarily wingless (that is, insect groups whose ancestors once had wings but that have lost them as a result of subsequent evolution). The ancestral glow colour for the last common ancestor of all living fireflies has been inferred to be green, based on They are small birds, with most species measuring 7.513 cm (35 in) in length. Anopheles (/ n f l i z /) is a genus of mosquito first described and named by J. W. Meigen in 1818. It forms a superspecies with its parapatric southern relatives, the Iberian grey shrike (L. meridionalis), the Chinese grey shrike (L. sphenocerus) and the American loggerhead shrike (L. ludovicianus).Males and females are similar in plumage, pearly grey above with a black The flowering plant family Amborellaceae, restricted to New Caledonia in the southwestern Pacific, is a basal clade of extant angiosperms, consisting of the most species, genus, family and order within the group that are sister to all other angiosperms (out of a total of about 250,000 angiosperm species). Aphids are distributed worldwide, but are most common in temperate zones.In contrast to many taxa, aphid species diversity is much lower in the tropics than in the temperate zones. The Pterygota (Ancient Greek: , romanized: pterugts, lit. History. The evolution of insect wings has been a subject of debate. The evolution of the wolf occurred over a geologic time scale of at least 300 thousand years. The grey wolf Canis lupus is a highly adaptable species that is able to exist in a range of environments and which possesses a wide distribution across the Holarctic.Studies of modern grey wolves have identified distinct sub-populations that live in close proximity to each other. In raphidiids, mating takes place in a "dragging position", while in inocelliids, the male adopts a tandem position under the female; copulation may last for Only Open Access Journals Only SciELO Journals Only WoS Journals Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. Eusociality (from Greek eu "good" and social), the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. Only Open Access Journals Only SciELO Journals Only WoS Journals Systematics, Evolution, & Biodiversity (SysEB) Branches Open submenu. The geometer moths are moths belonging to the family Geometridae of the insect order Lepidoptera, the moths and butterflies.Their scientific name derives from the Ancient Greek geo (derivative form of or "the earth"), and metron "measure" in reference to the way their larvae, or inchworms, appear to measure the earth as they move along in a looping La evolucin biolgica es el conjunto de cambios en caracteres fenotpicos y genticos de poblaciones biolgicas a travs de generaciones. Snakeflies are holometabolous insects, having a four-stage life cycle with eggs, larvae, pupae and adults. Password requirements: 6 to 30 characters long; ASCII characters only (characters found on a standard US keyboard); must contain at least 4 different symbols; Its place is largely taken by a hemocoel, a cavity that runs most of the length of the body and through which blood flows. Parasites grow within a vertebrate body tissue (often the liver) before entering the bloodstream to infect red blood cells. [2] [3] Los procesos evolutivos han producido la biodiversidad en cada nivel de la organizacin biolgica, incluyendo Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly.They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments.The wings are strengthened by a number of longitudinal veins, which The Red Queen hypothesis is a hypothesis in evolutionary biology proposed in 1973, that species must constantly adapt, evolve, and proliferate in order to survive while pitted against ever-evolving opposing species.The hypothesis was intended to explain the constant (age-independent) extinction probability as observed in the paleontological record caused by co-evolution between Such relationships can be of many different types. A phylogenetic tree (also phylogeny or evolutionary tree) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. Distribution. Here is a list of examples in which unrelated proteins have similar tertiary structures but different functions. All life on Earth is part of a single phylogenetic tree, indicating common ancestry.. Etymology. Our mission to accelerate the world's research. Sunbird-pollinated flowers are typically long, tubular, and red-to-orange in colour, showing convergent evolution with many hummingbird-pollinated flowers in the Americas. Evolutionary game theory (EGT) is the application of game theory to evolving populations in biology.It defines a framework of contests, strategies, and analytics into which Darwinian competition can be modelled. It is distinct from scavenging on dead prey, though many predators also scavenge; it The evolution of cardiotonic steroid (CTS) resistance via amino acid substitutions at well-defined positions of the Na +,K +-ATPase -subunit in multiple insect species spanning 6 orders. Following the success of Academia Letters an online platform for publishing and sharing short-form research articles, including orphaned findings and case studies Academia.edu is launching a suite of open access journals for the global academic community.The journals will provide new opportunities to disseminate research Winged aphids may also rise up in the day as high as 600 m where they are transported by strong winds. As nectar is a primary food source for sunbirds, they are important pollinators in African ecosystems. 'winged') are a subclass of insects that includes the winged insects. Eastern Branch; International Branch; North Central Branch; Pacific Branch; Southeastern Branch Post Doctoral Associate Position in Insect Vector Biology . The family Ursidae is one of nine families in the suborder Caniformia, or "doglike" carnivorans, within the order Carnivora.Bears' closest living relatives are the pinnipeds, canids, and musteloids. Catalogue Birds-of-paradise are closely related to the corvids.Birds-of-paradise range in size from the king bird-of-paradise at 50 g (1.8 oz) and 15 cm (5.9 in) to the curl-crested manucode at 44 cm (17 in) and 430 g (15 oz). In a rooted phylogenetic tree, each [1] Dicho proceso ha originado la diversidad de formas de vida que existen sobre la Tierra a partir de un antepasado comn. They can migrate great distances, mainly through passive dispersal by winds. The most recent understanding of the evolution of insects is based on studies of the following branches of science: molecular biology, insect morphology, paleontology, insect taxonomy, evolution, embryology, bioinformatics and scientific computing. It includes brief explanations of the various taxonomic ranks in the human lineage. Hummingbirds are birds native to the Americas and comprise the biological family Trochilidae.With about 361 species and 113 genera, they occur from Alaska to Tierra del Fuego, but the vast majority of the species are found in the tropics around the equator. The infraorder name Isoptera is derived from the Greek words iso (equal) and ptera (winged), which refers to the nearly equal size of the fore and hind wings. " Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey.It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha.Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Plasmodium is a genus of unicellular eukaryotes that are obligate parasites of vertebrates and insects.The life cycles of Plasmodium species involve development in a blood-feeding insect host which then injects parasites into a vertebrate host during a blood meal. [2] [3] Los procesos evolutivos han producido la biodiversidad en cada nivel de la organizacin biolgica, Flowers appeared and diversified relatively suddenly in the fossil record, creating what Charles Darwin described as the "abominable mystery" of how they It is estimated that the class of insects originated on Earth about 480 million years ago, in the Ordovician, at about the same Flowering plants. About 460 species are recognised; while over 100 can transmit human malaria, only 3040 commonly transmit parasites of the genus Plasmodium, which cause malaria in humans in endemic areas. Adult females typically have soft bodies and no limbs, and are concealed Lepidoptera (/ l p d p t r / lep--DOP-tr-) is an order of insects that includes butterflies and moths (both are called lepidopterans).About 180,000 species of the Lepidoptera are described, in 126 families and 46 superfamilies, 10 percent of the total described species of living organisms. Before mating, the adults engage in an elaborate courtship ritual, including a grooming behaviour involving legs and antennae. Coevolution is the evolution of two or more species which reciprocally affect each other, sometimes creating a mutualistic relationship between the species. The fossil from Rhyniella praecursor, is the oldest terrestrial arthropod, and was found in the famous Rhynie chert of Scotland.Given its morphology resembles extant species quite closely, the radiation of the Hexapoda can be situated in the Silurian or more. The light producing organ is clearly present. Evolution Fossil history. The oldest known fossil of the Lampyridae family is Protoluciola from the Late Cretaceous (Cenomanian ~ 99 million years ago) Burmese amber of Myanmar, which belongs to the subfamily Luciolinae. The great grey shrike (Lanius excubitor) is a large and predatory songbird species in the shrike family (Laniidae). International Scientific Journal & Country Ranking. In our online shop we offer the most diverse portfolio of bioresources for researchers from academia & industry. La evolucin biolgica es el conjunto de cambios en caracteres fenotpicos y genticos de poblaciones biolgicas a travs de generaciones. Some entomologists suggest that the wings are from paranotal lobes, or extensions from the insect's exoskeleton called the nota, called the paranotal theory. Other theories are based on a pleural origin. [1] Dicho proceso ha originado la diversidad de formas de vida que existen sobre la Tierra a partir de un antepasado comn. The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.. Biodiversity is the result of 3.5 billion years of evolution. Structural convergence. Like other arthropods, spiders are coelomates in which the coelom is reduced to small areas around the reproductive and excretory systems. It originated in 1973 with John Maynard Smith and George R. Price's formalisation of contests, analysed as strategies, and the mathematical criteria that can be used
