Appeal to antiquity? Appeal to nature? Bingo! - BioBlog

Alison Campbell Jun 13, 2018

I was idly skimming the Herald’s website when I came across an article with the headline “Is plant medicine really that effective?” Since the article appears to be in the nature of an advertorial, the answer is, it depends on who you ask.

Jean Balchin Apr 11, 2018

A recent study in Scientific Reports has concluded that lizards may have run on two feet (bipedally) as early as 110 million years ago. Although typical lizard locomotion is quadrupedal (on four feet), bipedalism is a behaviour exhibited by over 50 species of lizards. During bipedal locomotion, the forelimbs leave the ground and the trunk of the lizard is elevated; essentially the lizard … Read More
