Indiana University has organized an extensive survey on the roles of evolutionary biology and theory in modern medical education.  The survey targets students, alumni and faculty members of schools of medicine, nursing, veterinary medicine and public health.  The aims are to assess 1) the level of education in evolutionary biology that current health practitioners have and students are receiving, 2) opinions about the utility […]

For decades food manufacturers have marketed saccharin, along with other non-caloric artificial sweeteners (NAS), as healthy alternatives to sugar. Artificial sugar substitutes cannot be digested by humans and have been recommended for patients with diabetes  and for those trying to lose weight. However, a new report in the journal Nature suggests that NAS are harmful […]

Schiz-Authism copy Bernard Crespi has for several years developed evidence to support the theory, first proposed with CR Badcock, that schizophrenia and autism are flip sides of excessive or deficient maternal or paternal imprinting.   A study published today in the Proceedings of the Royal Society b finds further support from data on size at […]

By  Apari P, de Sousa JD, Müller V (2014) . in PLoS Pathog 10(8): e1004111. doi:10.1371/journal.ppat.1004111 In this Opinion piece we argue that the tendency of sexually transmitted infections (STIs) to cause infertility is likely to reflect an evolutionary adaptation of the pathogens. We use an evolutionary perspective to understand how STI pathogens may benefit […]

Adaptive variability in the duration of critical windows of plasticity:   Implications for the programming of obesity By  Jonathan CK Wells  Evol Med Public Health published 5 August 2014, 10.1093/emph/eou019 http://emph.oxfordjournals.org/content/early/2014/08/05/emph.eou019.abstract?papetoc   (open access) Abstract:  Developmental plasticity underlies widespread associations between early-life exposures and many components of adult phenotype, including the risk of chronic diseases. Humans take […]

Altshuler and colleagues (Nature Genetics, 2014) recently reported a study of about 150,000 individuals representing five different ancestral groups in which they identified twelve low-frequency variants of the gene SLC30A8 through either genomic sequencing or genotyping.  These variants are all predicted to truncate the gene product (ZnT8), a protein involved in zinc transport in beta […]

 Many have asked if there are meetings they can attend to learn more about evolutionary medicine and to get up-to-date on the latest advances.  Two just-announced major conferences will meet this need, one in Europe, one in the USA. Both will soon be inviting abstract submissions and meeting registrations. July 30–August 1, 2015 Evolutionary Medicine […]

Epistasis refers to the influence of one genomic mutation or variant on the phenotypic effects of another mutation or variant.  Based on available evidence and theory, this phenomenon has a major influence on evolutionary trajectories for organisms of all sorts.  The role of epistasis has been studied primarily in the context of adaptive evolutionary change.  […]

Toxoplasma gondii is an intracellular protozoan parasite that infects many different vertebrate species asexually and undergoes a sexual cycle after infecting cats (http://www.cdc.gov/parasites/toxoplasmosis/, 2013).  Parasite oocysts are potentially introduced into the human environment in cat feces.  T. gondii is of interest in clinical medicine because humans can serve as accidental intermediate hosts when they ingest […]
