This Darwin Day, consider donating in support of the Australian bushfires (and you could win a shirt)

Link: Boston.com


Imagine that after a terrifying, fast moving bushfire, that this was all that was left of your house and your town... and that's why this Darwin Day, we're taking a bit of a different approach, and we're asking for your donations to the Australian Red Cross in support of everyone affected by the bushfires. With hundreds dead, towns levelled, dead and injured wildlife, and survivors left with the clothes on their backs, even a small donation will mean a lot. Even better, if you make a donation on Darwin Day, you can be entered to win one of two free "Darwin Tree" shirts: the full details and the drawing are being hosted at the Sciencewomen blog. So please stop by their blog, make a donation of any amount to the Australian Red Cross, and email your confirmation to the Sciencewomen to be entered to win.

Additionally, for Darwin Day, we're also going to have a special sale on all "Darwin Evolutionary Tree" shirts in both shops:


Happy Darwin Day, and help make it a better day for everyone affected by the brushfires.


Update: We have two lucky winners and their shirts are already on their way! Many thanks again to all of you who showed such generosity on short notice.

There's still time for Darwin Day t-shirts!

Darwin Day is just around the corner, and it's a special one this year: the bicentenary of Charles Darwin's birth (Feb 12th, 1809). Darwin Day is a great opportunity not just to commemorate Charles Darwin, but also to actively promote the teaching and understanding of evolution and of the scientific approach in general.

First off, for everyone who's inquired about getting t-shirts in time for Darwin Day, yes it's still possible :) . You can see our full selection of evolution-themed t-shirts here, or you can go straight to our two most popular designs here:

We have various styles and color combinations to choose from, but if you don't see something you like, email us anytime for a custom color version at no extra charge.

Next, a couple of links to bring to your attention about Darwin Day and some (free!) ways to participate as well. Most notably is the 'Blog for Darwin' initiative, which will be a blog swarm of Darwin posts and sure to be a fascinating read: you can read about how to get involved here. If you're looking for a local event to celebrate Darwin Day at, check out DarwinDay.org's database of local celebrations here. There are also a lot of great Darwin tidbits posted at The Dispersal of Darwin including things like television programs during Darwin Day week.

Last but not least, if you've never read "The Voyage of the Beagle" this is a great time to pick it up and learn more about Charles Darwin the person. The book is a fascinating journal of Darwin's descriptions and reflections on local geology and biology, as well as anecdotes of his voyage. Darwin writes with an engaging voice and captures a lot of vibrant detail on his journey. A must-read for anyone interested in Darwin, evolutionary biology, or early geology.


Happy Darwin Day!
