The Animated Genome is a spirited 5-minute film that uses graphics to explain the makeup of your genome and how it affects life and health. It's part of Genome: Unlocking Life's Code, an exhibition at the Smithsonian Institution National Museum of Natural History.
Nature constantly engineers new and creative solutions to all sorts of problems—turning our stereotypes about sex upside-down along the way.
Indeed, at 6 million years of separation, the difference in [Y-chromosome] gene content in chimpanzee and human is more comparable to the difference in autosomal gene content in chicken and human, at 310 million years of separation.It is commonly said that the Human and Chimpanzee genomes share 99% or more identical DNA. In a surprising development about to be published in Nature, the Y-chromosomes of these two species were found to share only 70% of their DNA, raising important questions about the mode and tempo by which speciation from a common ancestor occurred. This finding may point the finger at the evolution of different patterns of sperm-competition and mating practices within these two species.

...Historians teach that they are mostly descended from different peoples: the Irish from the Celts and the English from the Anglo-Saxons who invaded from northern Europe and drove the Celts to the country’s western and northern fringes. But geneticists who have tested DNA throughout the British Isles are edging toward a different conclusion. Many are struck by the overall genetic similarities, leading some to claim that both Britain and Ireland have been inhabited for thousands of years by a single people that have remained in the majority, with only minor additions from later invaders like Celts, Romans, Angles, Saxons, Vikings and Normans. The implication that the Irish, English, Scottish and Welsh have a great deal in common with each other, at least from the geneticist’s point of view, seems likely to please no one.A United Kingdom? Maybe
