Darwinius Masillae
''Darwinius'' is a genus within the infraorder Adapiformes, a group of basal strepsirrhine primates from the middle Eocene epoch. Its only known species, ''Darwinius masillae'', lived approximately 47 million years ago (Lutetian stage) based on dating of the fossil site. The only known fossil, called Ida, was discovered in 1983 at the Messel pit, a disused quarry near the village of Messel, about 35 km (22 mi) southeast of Frankfurt, Germany. The fossil, divided into a slab and partial counterslab after the amateur excavation and sold separately, was not reassembled until 2007. The fossil is of a juvenile female, approximately overall length, with the head and body length excluding the tail being about . It is estimated that Ida died at about 80–85% of her projected adult body and limb length. The genus ''Darwinius'' was named in commemoration of the bicentenary of the birth of Charles Darwin, and the species name ''masillae'' honors Messel where the specimen was f ...

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Research Ethics
Research is " creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, econ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Method
The scientific method is an empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century (with notable practitioners in previous centuries; see the article history of scientific method for additional detail.) It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation. It involves formulating hypotheses, via induction, based on such observations; the testability of hypotheses, experimental and the measurement-based statistical testing of deductions drawn from the hypotheses; and refinement (or elimination) of the hypotheses based on the experimental findings. These are ''principles'' of the scientific method, as distinguished from a definitive series of steps applicable to all scientific enterprises. Although procedures vary from one field of inquiry to another, the underlying process is frequently the sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoax
A hoax is a widely publicized falsehood so fashioned as to invite reflexive, unthinking acceptance by the greatest number of people of the most varied social identities and of the highest possible social pretensions to gull its victims into putting up the highest possible social currency in support of the hoax. Whereas the promoters of frauds, fakes, and scams devise them so that they will withstand the highest degree of scrutiny customary in the affair, hoaxers are confident, justifiably or not, that their representations will receive no scrutiny at all. They have such confidence because their representations belong to a world of notions fundamental to the victims' views of reality, but whose truth and importance they accept without argument or evidence, and so never question. Some hoaxers intend eventually to unmask their representations as in fact a hoax so as to expose their victims as fools; seeking some form of profit, other hoaxers hope to maintain the hoax indefini ...

Simian
The simians, anthropoids, or higher primates are an infraorder (Simiiformes ) of primates containing all animals traditionally called monkeys and apes. More precisely, they consist of the parvorders New World monkeys (Platyrrhini) and Catarrhini, the latter of which consists of the superfamilies Cercopithecidae (Old World monkeys in the stricter sense) and apes (Hominoidea; including the genus ''Homo (genus), Homo''). The simians are sister group to the Tarsiiformes, tarsiers (Tarsiiformes), together forming the Haplorhini, haplorhines. The radiation occurred about 60 million years ago (during the Cenozoic era); 40 million years ago, simians colonized South America, giving rise to the New World monkeys. The remaining simians (catarrhines) split about 25 million years ago into Old World monkey, Cercopithecidae and apes (including humans). Taxonomy and evolution In earlier classification, New World monkeys, Old World monkeys, apes, and humans – collectively known as simians or ...
