Whatever has happened to Tangled Bank? This used to the evolution blog carnival that I read, but it seems to have died. However speciation has lead to some new carnivals in this domain such as:
Carnival of Evolution
3.7 billion years of molecular changes culminating in the emergence of matter inspecting its own origins and existence
A monthly carnival celebrating the diversity of life on this planet, and the methods we use to understand it.
A Blog Carnival Devoted to Genetics
Molecular and Cell Biology Carnival
A new venue for bloggers to contribute their thought and knowledge on topic pertaining to molecular and cell biology.
Oekologie is a traveling blog carnival reviewing the best ecology and environmental science posts of the month from all across the blogosphere.
