The study suggests that providers are testing patients who present with symptoms rather than proactively offering early detection.
Research suggests that the ability of humans to use social cues in cooperative situations may have evolved since the human lineage split from chimpanzees. In contrast, domestic dogs display an innate ability to solve social problems without prior training. This capacity is thought to be linked to the process of dog domestication.
