Hundeøjne er evolutionær menneskemanipulation
Indrøm det bare: Du kan heller ikke stå for de firpotede øjesten, der evindeligt tigger om bare én enkelt bid af din sommerlige sildemad. Men bare rolig, det er der ifølge en ny videnskabelig tidsskriftsartikel i Proceedings of the National Academy of Sciences en virkelig god grund til. Ved at sammenligne ansigtsmuskulaturen på henholdvis hunde og ulve har en gruppe forskere nemlig fundet ud af, at hunde – i modsætning til ulve – har en evne til at løfte deres indre øjenbryn på en sådan måde, at det fremkalder en stærkt plejende respons hos mennesker. De søde hundeøjne er simpelthen et evolutionært medlidenhedsinstrument. Du er afsløret, Fido.

Turns out our pet pooches have evolved human-like eyebrow muscles that let them make the sad faces that melt our hearts, according to a new study published on June 17, 2019 in the Proceedings of the National Academy of Sciences (PNAS). It involved dissecting the cadavers of domestic dogs and comparing them to those of wild wolves, our best friends' ancestors whom they branched off from around 33, 000 years ago (don't worry, no animals were killed for the research). A separate part of the study saw scientists videotaping two-minute interactions between dogs and a human stranger, then repeating the experiment with wolves, to closely track how much they used a specific muscle around the eye that produced an inner eyebrow raise.
