Did the first farmers deliberately domesticate wild plants ? [Evolution Letters Blogs]

Study with Benoît Pujol

A new study published in Evolution Letters, available now via Early View, has given us an interesting insight into the history of crop domestication. The work, by researchers at The University of Sheffield, UK, and the University of Toulouse, France, shows that seed enlargement probably evolved without the deliberate intention of early crop farmers. Humans have been artificially selecting for specific traits in domestic plants and animals for hundreds of years, selecting only the best individuals to breed and rejecting those with undesirable traits. However, this study shows that during the course of domestication, unintended changes have also occurred with dramatic effects.(...)

Investors and Exploiters in Ecology and Economics - Principles and Applications

Philipp Heeb

Overview

In the natural world, some agents (investors) employ strategies that provide resources, services, or information, while others (exploiters) gain advantages through these efforts. This behavior coexists and can be observed in many species and at many levels. For example, bacteria depend on the existence of biofilms to synthesize constituent proteins ; cancerous cells employ angiogenesis to feed a tumor ; and parents forgo vaccinating their children yet benefit from herd immunity. Two independent research traditions have developed to analyze this behavior—one couched in evolutionary theory championed by behavioral ecologists, the other in social science concepts advocated by economists. In this book experts from economics, evolutionary biology, behavioral ecology, public health, and anthropology look for commonalities in understanding and approach.

The contributors consider parasitic strategies in ecological and economic terms ; the governance of natural resources, with insights from “producer-scrounger models,” forest management, and game theory ; human health, discussing therapeutic opportunities, public health economics, and the integration of perspectives ; and behavioral, social, and institutional consequences of exploitation strategies.
