Daily briefing: Kissing might have evolved 21.5 million years ago

In a fascinating exploration of the behavioral traits shared among large apes, recent research suggests that kissing may not just be a uniquely human expression of affection, but a common practice among our closest relatives in the animal kingdom. Published in *Nature*, this study indicates that most large apes, including gorillas, chimpanzees, and orangutans, engage in kissing behaviors, which could reflect deep-rooted social bonding mechanisms. This insight leads to the compelling hypothesis that Neanderthals, our ancient cousins, likely partook in similar affectionate displays, shedding light on the emotional and social complexities of these extinct hominins. By examining the similarities in social structures and emotional expressions among these species, researchers aim to deepen our understanding of the evolutionary origins of human behaviors.

In addition to these intriguing findings about apes and human ancestry, the article highlights a concerning surge in measles cases across North America, raising alarms about public health implications worldwide. The resurgence is attributed to declining vaccination rates, driven by misinformation and vaccine hesitancy. This trend not only threatens the health of communities but also poses risks for global health security, as measles can spread rapidly across borders. Experts are calling for renewed efforts in public health education and vaccination campaigns to combat this preventable disease, emphasizing the importance of herd immunity in safeguarding vulnerable populations.

Lastly, the article discusses Canada’s innovative talent-attraction program aimed at bolstering its scientific workforce. In a bid to attract top-tier researchers and scientists from around the globe, Canada is implementing policies designed to streamline immigration processes for skilled individuals. This initiative not only addresses the growing demand for scientific expertise within the country but also positions Canada as a leader in fostering a diverse and inclusive scientific community. By creating an environment that values and supports international talent, Canada aims to enhance its research capabilities and drive innovation, ultimately contributing to global scientific advancement. The combination of these topics illustrates the interconnected nature of social behaviors, public health challenges, and the global scientific landscape, highlighting the importance of collaboration and understanding in addressing contemporary issues.
