An epigraph taken from the fourth-century Christian scholar Epiphanius hints at the purpose behind this ghostly babble: "I am you and you are me; where you are, I am, and in all things I find myself dispersed". Dispersal is our dusty fate, but our ashes and our drifting atoms can mingle.

The pattern of our relatively recent global dispersal from our home in Africa is reflected in our genes.
Perhaps one of the most surprising results of our study is the lack of support for rivers and highways as barriers to dispersal within our study area.
In the case of horizontal transmission in parasites, which is analogous to the level of dispersal in our model (see also [ 73]), theory generally predicts that increased horizontal transmission (z in our model) associates with higher parasite virulence (Q (1- n) in our model) [ 103].
For centuries, humans have been studying the historic dispersal of our species across the planet.
Ultra-distal dispersal from our simulations (>2500 km NE from source) is consistent with analyses of the CI ash layer identified in the Russian Plain21.
We assume that like many other group activities associated with collective movement, group dispersal in our model is initiated by leaders.
"We believe this piece of jawbone is the earliest direct evidence we have of modern humans in northwestern Europe, at a site at the very outermost limits of the initial dispersal of our species," said Tom Higham, deputy director of the Oxford radiocarbon accelerator unit, who led the study.
