... ATTLEBORO, Massachusetts (Reuters) - U.S. researchers say they have discovered what appears to be the oldest imprint of a prehistoric insect, made while the dragonfly-like creature was still alive.
Researchers in Great Britain and the United States have imaged the first high definition imprints that dolphin sounds make in water. They consider it a real breakthrough in deciphering dolphin ...

The answer, in part, has been discovered by an analysis of the platypus genome. Genomic imprinting appears to have evolved from a defense mechanism used by cells to knock down parasitic DNA.
