Last year Jeremy Jackson went to South Africa to collect a big prize at a conference. While there he met a young nature writer/photographer named Adam Welz. A few weeks ago Adam was ambling down the west coast of the U.S. and stopped by to visit for a day. In addition to breaking the news to me that more than half the plants in my yard are introduced species from South Africa (where the climate is so similar), he also is a great storyteller and amazing nature photographer (see the beavers).
If you have a few minutes and care to read some excellent natural history writing and see some amazing photograhic work, take a look at his blog. And maybe give him your insights on his question about the adaptive significance of yawning.
