Somebody was on Sulawesi before 118,000 years ago – from john hawks. Human-Neanderthal relationships may be at root of modern allergies – “Three genes inherited from our Neanderthal cousins may cause modern carriers to have an overly-sensitive immune system susceptible to allergies.” Grisly find suggests humans inhabited Arctic 45,000 years ago – “When they dated […]

Ancient Ethiopian genome reveals extensive Eurasian admixture throughout the African continent – “Here, we present a 12.5x coverage ancient genome of an Ethiopian male (‘Mota’) who lived approximately 4,500 years ago. We use this genome to demonstrate that the Eurasian backflow into Africa came from a population closely related to Early Neolithic farmers, who had […]

‘Tree of life’ for 2.3 million species released – “A first draft of the ‘tree of life’ for the roughly 2.3 million named species of animals, plants, fungi and microbes — from platypuses to puffballs — has been released. A collaborative effort among eleven institutions, the tree depicts the relationships among living things as they […]

What Your DNA Says About Medieval History – “A new study uses genetic data from living people to trace millennia-old migration patterns…. [M]uch of what Capelli and his colleagues discovered meshed with what historians already knew. For example, among northern Europeans, highest rate of admixing took place ‘around the late first millennium C.E., a time […]

a linkfest! =D Experimental evolution reveals hidden diversity in evolutionary pathways – “Our findings show that parallel genetic evolution is strongly biased by constraints and we reveal the genetic bases. From such knowledge, and in instances where new phenotypes arise via gene activation, we suggest a set of principles: evolution proceeds firstly via pathways subject […]

Genetic Variation in the Nuclear and Organellar Genomes Modulates Stochastic Variation in the Metabolome, Growth, and Defense – “Systems biology is largely based on the principal that the link between genotype and phenotype is deterministic, and, if we know enough, can be predicted with high accuracy. In contrast, recent work studying transcription within single celled […]

The genetics of Mexico recapitulates Native American substructure and affects biomedical traits – “We studied genomic variation within Mexico from over 1000 individuals representing 20 indigenous and 11 mestizo populations. We found striking genetic stratification among indigenous populations within Mexico at varying degrees of geographic isolation. Some groups were as differentiated as Europeans are from […]
