> if a person could generate the criticism given that simple input, how/why would it be that the authors who invest their own careers in the research wouldn't have anticipated and addressed it?
People who work in the field do also level the same criticism, quite frequently; teleological and anthropomorphizing explanations are extremely controversial topics in biology. The critique that some researchers jump to such explanations more quickly than the evidence warrants reappears frequently, and the critique that popular-science writers and journalists do so is basically universal. Most researchers also try to avoid doing so. You'll often find such explanations in scare quotes in papers, with it being clear that they're an evocative shorthand, not part of the scientific conclusions: the researchers really have a certain set of scientific conclusions about an observed phenomenon, which they refer to as a "funeral" as shorthand, but the scientific conclusions don't usually include any attempt to prove a strong analogy with human funerals. (It does somewhat depend on the journal how strictly such careful treatment of metaphors is enforced.)
In this case, the BBC article is a lot more anthropomorphizing than the original article (linked at the bottom), which doesn't make any conclusions about mourning or similarity to human funeral practices.
