Recombination has essential functions in mammalian meiosis, which impose several constraints on the recombination process. However, recent studies have shown that, in spite of these roles, recombination rates vary tremendously among humans, and show marked differences between humans and closely related ...
1We humans are in trouble. We have let loose a new evolutionary process that we don’t understand and can’t control. The latest leaps forward in artificial intelligence (AI) are rightly causing anxiety. Yet people are responding as though AI is just one more scary new technology, like ele...
Evolutionary medicine in its classical form assumes that since cultural evolution is faster than biological evolution, ailments of modern people are a result of mismatch between adaptations to the past environments and current situations. A core principle is that we, humans, having evolved for ...

The process that crafted both psychological and physiological adaptations (i.e., natural selection) is relatively slow. It takes time to evolve complex mechanisms. Although it takes significantly less time to shape and mould them, and evidence does suggest humans have undergone selection within the ...
thought to be the most common process in human evolution (Kimura, 1968). Moreover, when selection does occur, it is most often in the form of negative, or purifying,selection, which removes new deleterious mutations as they arise, rather than promoting the spread of new traits (Kreitman, ...
“It’s time for humans to become aware of the new reality and to collectively move where we want to as a species. We have the capability to do that and are already seeing signs of such movements. Our creativity, and our power to innovate and collaborate equip us with the perfect tools...
The Atapuerca humans shared many anatomical features with the later Neanderthals not present in modern humans, and analysis of their postcranial skeletons (the bones of the body other than the skull) indicated that they are closely related evolutionarily to Neanderthals. “This is really interesting...
Since evolution is a dynamic process, it is absolutely necessary to know where we come from to understand where we are at the present and where we are going in the future. It is a matter of momentum. Today, in all areas of science, a great deal of energy is being expended in the se...
Humans seem to share a number of predispositions that facilitate successful adoptive relationships, and the desire to raise children seems to be pervasive among modern humans. Despite these commonalities, patterns of adoption transactions vary greatly among contemporary human societies. This paper considers...
