Study reveals the progesterone receptor gene evolved rapidly in humans, but there is no evidence to support this happened because the changes were advantageous to our species. Researchers report the evolutionary force of selection was so weak that the gene accumulated harmful mutations as it evolved in humans. Progesterone receptor genes are vital during pregnancy as it supplies developing cells the ability to create progesterone receptors.

Origins of human language pathway in the brain at least 25 million years old

Studying auditory regions and brain pathways in humans, apes, and monkeys, researchers have identified a language pathway that interconnects the auditory cortex with frontal lobe regions. The language pathway in other primates suggests an evolutionary basis in auditory cognition and vocal communication.
