Dear Macroevolution.net readers: This is a small science website that serves 1.7 million visitors. It’s run by just one rarely well-funded biologist. And yet, like any other website, there are many expenses and a lot of work involved with its creation and maintenance. To provide a better user experience, this website is no longer running ads. Instead, you'll be seeing this banner at the top of the page whenever cash is running low. If everyone reading this gave $10, fundraising would last only two days a year. But, of course, most people come and go and leave no dough. So we'll just have to leave this banner up for a while and see what happens. But if you like Macroevolution.net, take a minute to make a donation with credit card or PayPal. And if you love it, give a little more! Thank you.
