The rise of informed consent and retreat from dependence upon unclaimed bodies in anatomy: An overview and assessment

Anatomical Sciences Education, EarlyView.
Abstract The development of anatomy has been marked by ethically questionable practices. This has been because the dissection of human bodies has always existed on the periphery of conventional society, necessitating a range of dubious ways of obtaining dead bodies for educational and research purposes.

Early cave art and ancient DNA record the origin of European bison

Nature Communications, 2016
The ancestry of the European bison (wisent) remains a mystery. Here, Cooper and colleagues examine ancient DNA from fossil remains of extinct bison, and reveal the wisent originated through the hybridization of the extinct Steppe bison and ancestors of ...

Long‐term trends in parasite diversity and infection levels: approaches and patterns

Biological Reviews, EarlyView.
ABSTRACT Parasites exist in every ecosystem, affecting nearly all organisms and playing a complex role in human societies. On the one hand, they contribute substantially to biodiversity and support ecosystem stability by performing essential ecological functions.

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

Biological Reviews, EarlyView.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,
