Evolutionary scientists do not know how the human brain's ability to process language supposedly evolved from a non-speaking ancestor. Recent technological advances have enabled scientists to explore this subject in new ways, and one researcher's review reveals two flaws that underpin the whole research effort.

Evolutionists have long maintained that modern primate species (including, in their view, humans) are branches on an evolutionary tree that lead back to a common ancestor. But the recent news of the published genome sequence for the gorilla in the journal Nature adds more solid data to the growing problem facing the current model of primate evolution.¹

Scientists recently studied laughter in different animals, such as rats and primates, by tickling them. One study compared the sounds made by humans and great apes:
