New theory addresses frozen Earth paradox
LEIPZIG, Germany, Sept. 6 (UPI) -- Max Planck Institute researchers in Germany and the Netherlands have used psychological research techniques to successfully reconstruct primeval cognition.
The scientists say that since fossils do not preserve thoughts, we have been unable to glean insights into the cognitive structure of our ancestors. But anthropologists at the Max Planck Institute for Psycholinguistics in the Netherlands and the Max Planck Institute for Evolutionary Anthropology in Germany used an alternative research method -- comparative psychological research -- to discover some strategies shaped by evolution are evidently masked very early on by the cognitive development process unique to humans.
"The unique human cognitive development seems to mask some of our evolved strategies even before we reach the age of three," said study leader Daniel Haun. "In future experiments, we therefore want to find out which areas of cognitive development in humans, for example language acquisition, are responsible for this restructuring of cognitive preferences."
The study appears in the journal Current Biology.
