A New Genus of Hominins Found in Kenya Whenever finding new fossils, most people get excited in learning more about the mysterious history of life on earth. No one fossil finding may be more important than another, but when discovering a fossil that adds a new genus name to a species, it gets exciting. This is especially true when the fossil gives more insight to the evolution of humans. In Kenya, a new genus of hominins was found. The new genus was assigned because this hominin had a combination
The Use of the Genus Virola as a Hallucinogen In South America Virola theiodora (Spr. ex Benth.) Warburg is one of many species of Virola used in the Amazon region as a hallucinogenic snuff. The plant differs in its pattern of usage by the indigenous people of this region. A reddish resin- like exudate is extracted from the cambial region of the bark of this slender tree and either snuffed or ingested orally. The major alkaloid constituent of this snuff appears to be 5-MeO-DMT with lesser amounts
The Genus Datura: From Research Subject to Powerful Hallucinogen Datura is one of the most interesting plants with hallucinogenic properties. Despite having a reputation as one of the 'darker' hallucinogens, it has been widely used by societies historically in both the Old World and the New, and continues to be today. For those interested in ethnobotanical uses of this plant world-wide, Datura is a fascinating topic. While being limited in its uses economically, the alkaloids contained in the
INTRASPECIFIC COMPETION: THE RESPONSE OF THE SUNFLOWER (genus HELIANTHUS) TO INCREASING DENSITY. INTRODUCTION All species, including plants, are impacted by density. Plants, of course, cannot leave their habitat as animals can, so they tend to respond in different ways to density. As populations grow more dense, they compete for resources such as food and space and are more prone to disease. Less dense populations are more susceptible to predation pressure. It is hypothesized that as plants in
they belonged to a previously unidentified species, which anthropologist Yohannes Haile-Selassie of the Cleveland Museum of Natural History and his colleagues are calling this species Ardipithecus Kadabba. Previous fossil finds from the identical genus has suggested that hominids called kadabba were instead a subspecies of the only other known Ardipithecus species, Ardipithecus ramidus”(Bower 2004). This new hominid is being addressed presently as Ardipithecus ramidus kadabba. “While Ardipithecus
respect to its genus). Now, however, this question with regard to the lack of diversity of the genus has come under fire. Richard Evan Schultes proposed a polytypic classification in 1974. Many questions still remain about Cannabis. Is there one species of Cannabis or are there several or more? Many scientists have argued that the genus is monotypic. Indeed, even the Federal government and at least a dozen states have enacted marihuana laws that are based upon the assumption that the genus consists
Aristotle’s Categories Things are said to be named 'equivocally' when, though they have a common name, the definition corresponding with the name differs for each. Thus, a real man and a figure in a picture can both lay claim to the name 'animal'; yet these are equivocally so named, for, though they have a common name, the definition corresponding with the name differs for each. For should any one define in what sense each is an animal, his definition in the one case will be appropriate to that
Scientific Classification in Biology Classification in biology, is the identification, naming, and grouping of organisms into a formal system. The vast numbers of living forms are named and arranged in an orderly manner so that biologists all over the world can be sure they know the exact organism that is being examined and discussed. Groups of organisms must be defined by the selection of important characteristics, or shared traits, that make the members of each group similar to one another
from its salts by alkalis. Many of the commercial alkaloids are found in the genus Strychnos. Strychnine was the first alkaloid to be identified in plants of the genus Strychnos, Family Loganiaceae. Strychnos, created by Linnaeus in 1753, is a genus of trees and climbing shrubs of the gentian order. From the standpoint of biological diversity, it is the most important genus of the Loganiaceae family (6 p.1). The genus contains 196 various species and is distributed throughout the warm regions of
available and the ability to degrade it is a distinct advantage. As the species evolved to live on skin the trait remained, as it had no negative effect on survivability. Micrococcus is a genus within the Micrococcaceae family. With the use of 16s RNA in bacterial taxonomy the genus has recently been revised2. The genus now includes three species, M. luteus, M. lylae and M. antarcticus3. M. luteus is a common yellow gram-positive coccus and roughly 0.5-2.0mm in diameter. Cells appear in pairs, tetrads
Diversity and Distribution of Eucalyptus Eucalyptus is a genus of hardwood evergreen forest trees, and is the most conspicuous element of Australian vegetation. Its members constitute 95 percent of the continent's forests and are the dominant trees of Australia's woodlands (Kelly 1969). It is an extremely diverse group, with approximately 500 named species and subspecies and nearly 200 described hybrid varieties (Blakely 1965). The genus is overwhelmingly endemic to the Australian mainland and Tasmania
Nymphaeaceae (Water-Lily) family. The blue lotus has several common names including: Egyptian lotus, blue water lily, and sacred lily of the Nile. It should not be confused with the "blue lily" or Agapanthus africanus, a plant of an entirely different genus (Anonymous, 1999). Be careful also not to confuse it with the Nymphaea lotus, which is the "white lotus". Fossils of this plant have been dated back to the Jurassic period, about 160 million years ago. Amazingly, the fossils suggest that the blue lotus
toes, and adapted to various diets. In other words, horse evolution had no inherent direction. We only have the impression of straight line evolution because only one genus happens to still be alive, which deceives some people into thinking that the one genus was somehow the target of all the evolution. Instead, that one genus is merely the last surviving branch of a once mighty and sprawling bush. Tracing a line of descent from Hyracotherium to Equus reveals several apparent trends: reduction
organisms discussed I this report are humans and Frogs. The Taxonomy of an organism includes kingdom, phylum, class, order, family, genus, and species. Humans are classified by the kingdom animalia, phylum chordate, class mammalia, order primates, family hominidae, genus homo, and species homo sapiens. Frogs are classified as kingdom animalia, phylum chordate, and genus and species Rana pipens. A frogs habitat is usually spent on land for most of its adult life. However frogs reproduction and development
their calls and the fact that the Cope Gray Tree Frog is diploid while the Gray Tree Frog is tetraploid (NPWRC, 2004). The Gray Tree Frog is classified as follows: Kingdom: Animalia Phylum: Chordata Class: Lissamphibia Order: Anura Family: Hylidae Genus: Hyla Species: H. versicolor The Grey Tree Frog is about two inches in length. Its head is short and broad and its body corpulent (Dickerson, 1969). With a white belly, white rectangular spot under both of its eyes, yellowish orange markings on the
The Meaning of Service Service is a word used constantly. The word service has an impression on many people. For example; people who work as lifeguards view their work as a service to the community. Naturally, based on working as a lifeguard their definition of service would be an action beneficial to the well-being of others. Not surprisingly, a similar definition was found in the Oxford English Dictionary (OED). Service is described in the Oxford English Dictionary as "the action of serving
species as living organisms (Worcester, 2015). Carl Linnaeus developed a system where animals were amongst one of the broad group in kingdoms, which he then divided into classes and were further identified by a Genus or a species name and this was known as the Linnaean classification system. A genus includes species of individual organisms grouped
estimated these fossils to be about 47 million years old. According to author David Braun of National Geographic News, “The researchers have classified one, Rodhocetus balochistanensis, as a new species of an existing genus, and the other, Artiocetus clavis, as a new species and new genus” (Braun, 5). The discovery of these two fossils suggests that the closest living relative of these primitive whales could possibly be the modern day hippopotamus. This suggested relationship is based on similarities
serious challenge to the materialism or the mind-brain identity theory. Based on this existence we can put forward the antimaterialist argument of machines. Intelligence is a class of mental processes such that the mind is the genus and the intelligence is a species of this genus. The capacity to solve problems is a clear and definite criterion of intelligence. Again, like in the mind, the human intelligence is the paradigm of the intelligence. There are also three kinds of intelligence: human, animal
resemblance of the canine teeth of a lion, giving the plant its most familiar name of "Dandelion," (AAE, 1995) Dandelions, known to the botanist as Taraxacum officinale, are classified in the Composite (Compositae) family of flowering plants. The genus name, Taraxacum is derived from the Persian word for "bitter herb," (Myer, 1994). Accompanying the golden ruse of the dandelion are the daisies, aster, sunflowers, goldenrod, Joe Pye weed and many other wildflowers. Several common names, used for
