...I wonder then, where's the tipping point from dna to human? Is personality the only thing that makes us 'human'? -this post was made from 100% dick-free words
I don't think there is a tipping point. We covered 'vagueness' in one of my Metaphysics classes, an interesting topic.
At what point does a "desk" stop being a "desk" if you remove 1 atom at a time? Is there a % of atoms that supplies the "desk-ness" to the "desk", and once it's passed, does it stop being a desk? I think this is true with humans too; if we were to take 10 samples of humans from every 100 years back until we had a fossil we consider "not-human", I think there would be a very gradual change in human qualities over the given length of time.
People also assume human ancestory is uninterrupted and a steady long line of abrupt and extraordinary changes (e.g. One day a kid is born with bird wings, and that's how we evolve). This couldn't be further from the truth, lots of homo-species overlapped in the time line, some shared direct lineage, some didn't. Also, the mutations that take place are minuscule, but over x amount of time, the mutations can really hone themselves to a purpose through natural selection.
So, really what I'm saying is that humans look for rigid lines to be drawn where there are none. Whether it's defining what a desk is, or what a human is; there is no 100% clear answer.
