Bones, Stones and Molecules provides some of the best evidence for resolving the debate between the two hypotheses of human origins. The debate between the 'Out of Africa' model and the 'Multiregional' hypothesis is examined through the functional and developmental processes associated with the evolution of the human skull and face and focuses on the significance of the Australian record. The book analyzes important new discoveries that have occurred recently and examines evidence that is not availableelsewhere. Cameron and Groves argue that the existing evidence supports a recent origin for modern humans from Africa. They also specifically relate these two theories to interpretations of the origins of the first Australians. The book provides an up-to-date interpretation of the fossil, archaeological and the molecular evidence, specifically as it relates to Asia, and Australia in particular. * Readily accessible to the layperson and professional * Provides concise...

Fauna of Africa, in its broader sense, is all the animals living on the African continent and its surrounding seas and islands. The more characteristic African fauna is found in the Afrotropical ecoregion - formerly called Ethiopian (the Sub-Saharan Africa). Lying almost entirely within the tropics, and equally to north and south of the equator creates favourable conditions for rich wildlife.

Goes beyond the reporting of genome sequencing information to explore the use of genome sequences to formulate and answer questions related to interspecies interactions among human oral microbes. Focuses on how knowledge of a genome sequence can be applied to answer a research question and emphasizes mixed-species community life and oral microbial biofilms

Known for its thorough coverage of diversity, ecology, and environmental issues, this comprehensive book engages readers with integrated, relevant case studies and challenges them with thought-provoking questions throughout each chapter. The fully revised Biology: Life on Earth, Ninth Edition, has the same friendly writing style appreciated by thousands of readers, but with greater emphasis on engaging, real-world applications. New to this edition are “Case Study Continued”sections, which connect a chapter’s case study to relevant biological topics covered in the chapter, and “Have you ever wondered?” features that respond to commonly asked questions from students. Thoroughly revised illustrations and expanded critical thinking questions have been added to each chapter and are supplemented by the powerful new MasteringBiology® program that helps students make effective use of their study time outside of the classroom. For coverage of plant and animal anatomy &...

Human mitochondrial genetics is the study of the genetics of the DNA contained in human mitochondria. Mitochondria are small structures in cells that generate energy for the cell to use, and are hence referred to as the "powerhouses" of the cell. Mitochondrial DNA (mtDNA) is not transmitted through nuclear DNA (nDNA). In humans, as in most multicellular organisms, mitochondrial DNA is inherited only from the mother's ovum. The mitochondrial DNA inherited by a female from its mother's egg produces mitochondria to supply the energy to sustain the female's eggs. Mitochondrial inheritance is therefore non-Mendelian, as Mendelian inheritance presumes that half the genetic material of a fertilized egg (zygote) derives from each parent.

High Quality Content by WIKIPEDIA articles! Pyrimidine is a heterocyclic aromatic organic compound similar to benzene and pyridine, containing two nitrogen atoms at positions 1 and 3 of the six-member ring. It is isomeric with two other forms of diazine. In DNA and RNA, these bases form hydrogen bonds with their complementary purines. Thus the purines adenine (A) and guanine (G) pair up with the pyrimidines thymine (T) and cytosine (C), respectively. In RNA, the complement of A is U instead of T and the pairs that form are adenine:uracil and guanine:cytosine.

High Quality Content by WIKIPEDIA articles! In biochemistry, a receptor is a protein molecule, embedded in either the plasma membrane or the cytoplasm of a cell, to which a mobile balls signaling molecule may attach. A molecule which binds to a receptor is called a ligand, and may be a peptide or other small molecule, such as a neurotransmitter, a hormone, a pharmaceutical drug, or a toxin. When such binding occurs, the receptor undergoes a conformational change, which ordinarily initiates a cellular response. However, some ligands (e.g. antagonists) merely block receptors without inducing any response. Ligand-induced changes in receptors result in cellular changes which constitute the biological activity of the ligands.

High Quality Content by WIKIPEDIA articles! Renewable heat is an application of renewable energy and it refers to the renewable generation of heat, rather than electrical power (e.g. replacing a fossil fuel boiler using concentrating solar thermal to feed radiators). Many colder countries consume more energy for heating than electrical power. For example, in 2005 the United Kingdom consumed 354 TWh[1] of electric power, but had a heat requirement of 907 TWh, the majority of which (81%) was met using gas. The residential sector alone consumed a massive 550 TWh of energy for heating, mainly in the form of gas. Almost half of the final energy consumed in the UK (49%) was in the form of heat, of which 70% was used by households and in commercial and public buildings. Households used heat for mainly for space heating (69%) and heating water.
