Thanks for replying in such a time that shows you have not read them. It would take near an hour to glide through the sources sent, you replied in a few minutes, and if done, you would see only two were about crows, one was about elephants, and you provided only a personal opinion in response. No peer review from your side? Shall I post the study of chimpanzees next?

You aren’t looking for peer reviewed sources if youre so quick to denounce them. You hold no credibility over the sources sent. Those are from leading experts. Youre a lemmy user. Big difference.
