If you want a little science denialism with your chordate evolution news, you can go with this knee-slapper from The Christian Post. It turns out that these footprints don’t add yet another useful data point to the evolutionary theory, rather they overthrow the whole thing because the earliest known date of tetrapods was pushed back 20 million years. *Snickers*
