Daily briefing: Kissing might have evolved 21.5 million years ago

In a fascinating exploration of social behaviors among primates, recent research published in *Nature* highlights that most large apes engage in kissing, a behavior that likely extends to our ancient relatives, the Neanderthals. This study sheds light on the evolutionary roots of affection and bonding, suggesting that such intimate gestures are not solely a human trait but are shared among our closest relatives in the animal kingdom. Observations of kissing in species like gorillas and chimpanzees indicate that these acts serve various social functions, from reinforcing relationships to establishing peace among group members. The implications of this research extend beyond mere curiosity; understanding these behaviors can provide insights into the social structures of early hominins and how they may have navigated complex social environments.

In addition to the intriguing findings about ape behavior, the article addresses the concerning resurgence of measles in North America, which poses significant public health challenges. The spike in measles cases, attributed to declining vaccination rates, serves as a stark reminder of the importance of herd immunity and the potential consequences of misinformation surrounding vaccines. This surge not only threatens the health of individuals but also raises alarms about global health security, as diseases can quickly cross borders. Public health officials are urging communities to prioritize vaccination to curb the spread and protect vulnerable populations, emphasizing that the fight against preventable diseases is far from over.

Furthermore, the article highlights Canada’s innovative talent-attraction program aimed at bolstering its scientific community. This initiative seeks to draw international researchers and experts to Canada, thereby enhancing the country’s research capabilities and fostering a vibrant scientific ecosystem. By offering competitive incentives and support for foreign scientists, Canada is positioning itself as a global hub for innovation and research. This strategy not only promises to advance scientific knowledge but also reflects a broader trend of nations recognizing the value of attracting talent to drive economic growth and address pressing global challenges. As countries navigate the complexities of a post-pandemic world, initiatives like these underscore the importance of collaboration and knowledge exchange in the pursuit of scientific advancement.
