Daily briefing: Kissing might have evolved 21.5 million years ago

In a fascinating exploration of primate behavior, a recent article published in *Nature* reveals that most large apes engage in kissing, a behavior that may also have been present among Neanderthals. This finding sheds light on the social and emotional complexities of these species, suggesting that kissing could be a fundamental aspect of bonding and communication among primates. Researchers observed various large ape species, including chimpanzees, gorillas, and orangutans, displaying kissing behaviors, which often serve to strengthen social ties and establish alliances within groups. This insight not only enriches our understanding of ape social structures but also invites us to reconsider the emotional lives of our ancient relatives, the Neanderthals, who likely shared similar social behaviors.

In addition to the intriguing revelations about ape behavior, the article highlights a concerning surge of measles cases in North America, which raises alarm bells for global public health. The resurgence is attributed to declining vaccination rates, fueled by misinformation and vaccine hesitancy. Health experts warn that this trend could lead to outbreaks reminiscent of those seen prior to widespread vaccination campaigns. The implications of this rise in measles cases extend beyond North America, as infectious diseases do not recognize borders, posing a threat to global health security. This situation underscores the critical importance of maintaining high vaccination coverage to prevent the re-emergence of vaccine-preventable diseases.

Furthermore, the article discusses Canada’s innovative talent-attraction program aimed at bolstering its scientific community. In a bid to attract top-tier researchers and innovators, Canada is implementing initiatives that streamline immigration processes for scientists and their families, providing them with opportunities to contribute to the nation’s research landscape. This bold strategy reflects Canada’s commitment to fostering scientific advancement and addressing critical global challenges, such as climate change and public health crises. By creating an environment conducive to scientific inquiry and collaboration, Canada not only enhances its own research capabilities but also positions itself as a leader in the global scientific community. This multifaceted approach to science and public health illustrates the interconnectedness of human behavior, health policies, and international collaboration in addressing both historical and contemporary challenges.
