Denisovans are ancient humans represented by various teeth and a finger bone found in a Siberian cave. Their claim to fame is largely based on the DNA extracted from these few fragments of human remains. According to evolutionists, they are more closely related to Neanderthals than modern humans.

The planaria, a type of flatworm, has an amazing capacity to regenerate a new body from just fragments of tissue. Its genome has just been sequenced. The surprising result is a completely unexpected evolutionary conundrum.
