Once again, bravo! A very fun interesting read.

Um yes, it seems kind of silly that scientists think that this would be true for all species, just from observing nature: "the molecular clock's premise that all species have similar mutation rates"

"Contrary to Emanuel Margoliash's original assumption that genetic distance could be universally determined by the rate of mutation in a blood protein, and then calculated for all life on earth by time alone - meaning that ALL MUTATIONS ON EARTH WERE SET BY THAT PROTEIN AND had a biologically-universal rate that is constant and steady - the genetic equidistance phenomenon could also be explained by MGD's assumption that mutation-rates are specific to each gene and might vary across species and within populations."

What if they haven't found all species on Earth yet, what if one species doesn't contain that blood protein yet is "alive?" What if they don't really understand or calculate time accurately yet?

Also, the MGD theory seems to better reflect the infinite complexity that is life on Earth, and in our universe. To simply lump it all together in a universal rate doesn't seem to reflect reality.

I think of a Star Trek episode in which there were two crews on the same ship, but they experienced time differently so one crew was in a hyper speed dimension in comparison to the other crew, yet both experienced time in their dimension as natural. So what is "normal" for one species with respect to time and space might be entirely different for another species. It seems more logical that their genetic evolutions would be different. They are often under vastly different time/space/environmental pressures, some of which we cannot accurately measure yet, like dark matter and energy and even gravity. Thank you for these articles, they are immensely though provoking!

Wow thanks so much for reading and for that wonderful metaphor at the end!! And that's actually completely accurate since even without intergalactic differences creating time-warps like in Interstellar, just the idea of more and less complex organisms can effectively do the same thing - what's a sunset to fruit fly, or a ten-thousand year old tree?
