Over the last few decades, there has been a push towards evidence-based medicine, with the medical fraternity recognising and embracing the improved outcomes brought about by this approach. Central to this is the ability of healthcare professionals across all levels to be able to understand and undertake scientifically sound efforts to gather and learn from this evidence. This can be on a local level, for example departmental audits, or on a national or international level, as is the case with large (...) randomised controlled trials. Unfortunately, although academic medicine topics such as research and teaching are often discussed and taught at medical schools - many of which are at the forefront of international research efforts - medical students and junior doctors rarely get the chance to participate in any real-world studies, or indeed critique any practice changing studies in a meaningful way for themselves. The situation in regard to teaching is similar. Peer to peer teaching opportunities may be limited to self-arranged sessions with little to no guidance or formal training in how to do this key task, which will be crucial for the rest of one's career. This is despite these activities being recognised as essential by undergraduate and post-graduate educators. In fact, they are a key part of selection for postgraduate employment. Candidates that demonstrate awareness of and proficiency with research and other academic activities such as teaching are highly sought after. However, many candidates, particularly those who don't take time out of their undergraduate programmes or pursue a higher degree, tend not to have had the exposure and opportunities to engage with these academic activities as students and junior healthcare professionals. Many will have never undertaken any formal research or teaching during this time. Furthermore, we have found that many students with an interest in medical research don't have the skills and experience required to get started, and may lack mentors and senior colleagues with the time, interest or experience to help them.

Motherese is a form of affective prosody injected automatically into speech during caregiving solicitude. Affective prosody is the aspect of language that conveys emotion by changes in tone, rhythm, and emphasis during speech. It is a neocortical function that allows graded, highly varied vocal emotional expression. Other mammals have only rigid, species-specific, limbic vocalizations. Thus, encephalization with corticalization is necessary for the evolution of progressively complex vocal emotional displays.

Epigenetics impacts gene–culture coevolution by amplifying phenotypic variation, including clustering, and bridging the difference in timescales between genetic and cultural evolution. The dual inheritance model described by Uchiyama et al. could be modified to provide greater explanatory power by incorporating epigenetic effects.
