Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to the human genome, and its current effects. Differences between genomes have anthropological, medical, historical and forensic implications and applications. Genetic data can provide important insights into human ...
Denny represents the first ancient individual discovered whose parents belonged to two discrete species of humans, which will provide a unique opportunity for future comparative genetic studies. [1] [2] The discovery of Denny and other paleogenetic data acquired since 2010 show that human evolution should not be conceptualized as a simple ...
Some types of non-coding DNA are genetic "switches" that do not encode proteins, but do regulate when and where genes are expressed (called enhancers). [30] Regulatory sequences have been known since the late 1960s. [31] The first identification of regulatory sequences in the human genome relied on recombinant DNA technology. [32]
Scientists have known since the first Neanderthal genome was sequenced in 2010 that early humans interbred with Neanderthals, a bombshell revelation that bequeathed a genetic legacy still ...
One of the most significant initial discoveries on that front was found in 1929 at a site near Clovis, New Mexico. Mammoth bones and stone tools at the site date back to 13,000 years ago.
Cave paintings (such as this one from France) represent a benchmark in the evolutionary history of human cognition. Victorian naturalist Charles Darwin was the first to propose the out-of-Africa hypothesis for the peopling of the world, [40] but the story of prehistoric human migration is now understood to be much more complex thanks to twenty-first-century advances in genomic sequencing.
Who We Are and How We Got Here is a 2018 book on the contribution of genome-wide ancient DNA research to human population genetics by the geneticist David Reich.He describes discoveries made by his group and others, based on analysis and comparison of ancient and modern DNA from human populations around the world.
The Denisovans of Eurasia, a hominid species related to Neanderthals and humans, was discovered as a direct result of DNA sequencing of a 41,000-year-old specimen recovered in 2008. Analysis of the mitochondrial DNA from a retrieved finger bone showed the specimen to be genetically distinct from both humans and Neanderthals.
