One thing that I often hear criticized about this particular visualization is that it still somehow conveys the misleading idea that humans are the most advanced, most evolved organisms, sitting on the far right of the diagram.

One must not forget that it's not only "from bacteria to humans", the bacteria themselves have also evolved equally long and arguably even further - humans are but one tiny leaf among the mighty branched tree of life.

My personal favorite is this one here because it captures the relative insignificance of homo sapiens.

I agree though. Great visual explanation nonetheless. :-)
