The World's First Volunteer Network by roya elghanian. WWH was created to enable volunteers and organisations to share, connect, and make a difference. At WWH our philosophy is "why Pay to Volunteer? In answer to this we developed a social networking site that provides volunteers with hundreds of low/no cost volunteer opportunities.
Understanding how and why we evolved such large brains is one of the most puzzling issues in the study of human evolution. A new study argues that carbohydrate consumption, particularly in the form of starch, was critical for the accelerated expansion of the human brain over the last million years. Eating meat may have kick-started the evolution of bigger brains, but cooked starchy foods together with more salivary amylase genes made us smarter still.
