How about if we just retire Dollo's Law altogether?

How about if we just retire Dollo's Law altogether? | PCLS - Physics Chemistry Lab Science | Scoop.it
Earlier this month, there was a flurry of headlines in the pop-sci press that exasperated me. "Have scientists discovered reversible evolution?" was one; "Evidence of Reverse Evolution Seen in Dust...
jlinzel's insight:

For my IB's find the paragraph about evolutionary 'direction': "“Evolutionary traffic can only move forward”? Please, define “forward” in this context for me. Evolution doesn’t have a direction. You can talk about a temporal sequence of historical changes in a gene, for instance, but from the point of view of the process, there’s no “forward” or “backwards”, only change over time. Is a genetic deletion a backwards step? Is a duplication a forward step? If a mutation changes a cytosine to an adenine, is that going forward, and if there is a revertant, a mutation that changes that adenine back to a cytosine, is that going backwards? I keep hearing this talk about directions, and it doesn’t even fit into my understanding of the process of evolution. Direction is always something people infer retrospectively."
