A new study compares the relative rate of molecular evolution between humans and chimps with that of their lice. The researchers wanted to know whether evolution marches on at a steady pace in all creatures or if subtle changes in genes – substitutions of individual letters of the genetic code – occur more rapidly in some groups than in others. A report of the study appears in the Proceedings of the Royal Society B. The team chose its study subjects because humans, chimps and their...

(Ivanhoe Newswire)– The human brain is the center of the human nervous system and has the same general structure as the brains of other mammals, but it´s than expected. According to a pair of studies, a partial, duplicate copy of a gene appears to be responsible for the critical features of the human brain that distinguish us from our closest primate kin. The momentous gene duplication event occurred about two or three million years ago, at a critical transition in the evolution...

Orangutans Harbor Ancient Primate Alu

Alu elements infiltrated the ancestral primate genome about 65 million years ago. Once gained an Alu element is rarely lost so comparison of Alu between species can be used to map primate evolution and diversity. New research published in BioMed Central's open access journal Mobile DNA has found a single Alu, which appears to be an ancestral great ape Alu, that has uniquely multiplied within the orangutan genome. Analysis of DNA sequences has found over a million Alu elements within each...

Nearby Chimpanzee Populations Show Greater Genetic Diversity Than Distant Human Populations

Chimpanzee populations living in relatively close proximity are substantially more different genetically than humans living on different continents, according to a study published March 2 in PLoS Genetics. The study suggests that genomics can provide a valuable new tool for use in chimpanzee conservation, with the potential to identify the population of origin of an individual chimpanzee or the provenance of a sample of bush meat. Common chimpanzees in equatorial Africa have long been...

British scientists say they are using chimpanzees to study so-called mobile DNA that is found in the genomes of humans and other primates. Researchers at the University of Leicester said most genes are always found in the same place in the genome. But the genes the scientists are studying have been moving around the genome throughout mammalian and primate evolution, and are still doing so. This makes every human -- and every chimpanzee for that matter -- a little bit different at the DNA...

WASHINGTON (Reuters) - What makes a human different from a chimpanzee? Not much, but the little genetic differences clearly count for a lot, said scientists who have mapped the complete chimp genome and compared it to the human gene map. They said their findings, published in the journal Nature on Wednesday, would shed light on why people get Alzheimer's disease, certain cancers and even AIDS, which chimpanzees do not. The researchers said the findings were yet more proof that...


Word of the Day
conjunto
  • A style of popular dance music originating along the border between Texas and Mexico, characterized by the use of accordion, drums, and 12-string bass guitar and traditionally based on polka, waltz, and bolero rhythms.
The word 'conjunto' comes through Spanish, from Latin coniūnctus, past participle of coniungere, to join together; see conjoin
