The Journey of Man: A Genetic Odyssey is a 2002 book by Spencer Wells, an American geneticist and anthropologist, in which he uses techniques and theories of genetics and evolutionary biology to trace the geographical dispersal of early human migrations out of Africa. The book was made into a TV documentary in 2003.
In biogeography, geodispersal is the erosion of barriers to gene flow and biological dispersal (Lieberman, 2005.; [1] Albert and Crampton, 2010. [2]). Geodispersal differs from vicariance, which reduces gene flow through the creation of geographic barriers. [3]
Advanced Placement (AP) Human Geography (also known as AP Human Geo, AP Geography, APHG, AP HuGe, APHug, AP Human, HuGS, AP HuGo, or HGAP) is an Advanced Placement social studies course in human geography for high school, usually freshmen students in the US, culminating in an exam administered by the College Board.
Human-aided dispersal, an example of an anthropogenic effect, can contribute to biological dispersal ranges and variations. [36] Informed dispersal is a way to observe the cues of biological dispersal suggesting the reasoning behind the placement. [37] This concept implies that the movement between species also involve information transfer.
Biotic interchange is the process by which species from one biota invade another biota, usually due to the disappearance of a previously impassable barrier. [1] These dispersal barriers can be physical, climatic, or biological and can include bodies of water or ice, land features like mountains, climate zones, or competition between species.
Overview map of the peopling of the world by early humans during the Upper Paleolithic, following the Southern Dispersal paradigm. The so-called "recent dispersal" of modern humans took place about 70–50,000 years ago. [60] [61] [62] It is this migration wave that led to the lasting spread of modern humans throughout the world.
Getting enough rest gives your body time to repair and grow stronger, while carbs, omega-3s, and other key nutrients may help fuel your workouts and recovery, according to a 2024 study published ...
For example, in 2001 Wolpoff and colleagues published an analysis of character traits of the skulls of early modern human fossils in Australia and central Europe. They concluded that the diversity of these recent humans could not "result exclusively from a single late Pleistocene dispersal", and implied dual ancestry for each region, involving ...
