The connected sequence between that links modern humans (Homo sapiens) with, for example, Homo erectus or Australopithecus afarensis is the same as the sequence that links me with my 20-greats-grandmother extended over about 100,000 generations instead of 22. The fact that I don't know all the links between either between me and my Homo erectus and Australopithecus afarensis ancestors, or between me and my 20-greats-grandmother, doesn't mean that those links didn't exist or that they were not represented by real living hominins.On evolution charts, such as the one I showed you with Richard Dawkins, there is no "connected sequence between me and my 20-greats-grandmother".
The dots will either represent a new species, or a new genus, or both.
Either way -- drawing a line between a genus and its various species (micro), or drawing a line between a genus and another genus (macro) -- it's still a game of connect-the-dots.
But drawing a line from me to my dad to my grandfather and so on for twenty generations (micro) is taking my point too far.
