"Thus, fundamental reproductive and social behavioral changes probably occurred in hominids long before they had enlarged brains and began to use stone tools," the research team concluded.
"Prema tome, fundamentalne promjene u reprodukciji i društvenom ponašanju vjerojatno su se pojavile kod hominida dugo prije nego što su imali velik mozak i počeli koristiti kamene alate," zaključio je istraživački tim.
