Revision as of 16:26, April 8, 2007
, 16:26, April 8, 2007→eh what?: Different possible classification systems.
:::That is only relevant if you are using that as part of your classification system. They've also found that humans have about 50% of their DNA in common with bananas, so does that make us 50% plants? [[User:Philip J. Rayment|Philip J. Rayment]] 11:28, 8 April 2007 (EDT)

::::No, but it indicates that humans and plants forked from each other a lot earlier than humans and chimps did. [[User:Teresita|Teresita]] 11:48, 8 April 2007 (EDT)

:::::Whether or not they forked at all is a separate issue. But if sharing 50% of our DNA does not make us 50% plants, why does sharing 98% of our DNA with animals (well, one type only) make us 98% animal? [[User:Philip J. Rayment|Philip J. Rayment]] 12:26, 8 April 2007 (EDT)
:Phil, that question reveals a level of ignorance so profound that I'm not sure where to start. The kingdoms of Animalia an Plantae branched off very far in the past, far enough that, while we share enough DNA to show that we both originated from common ancestors on Earth, evolution as separated us enough that we not only are separate species, but actually in separated kingdoms.[[User:palmd001|PalMD]]<sup>[[User_talk:palmd001|talk]]</sup> 12:05, 8 April 2007 (EDT)

::You confuse disagreement for ignorance. You are not telling me something that I've never heard, but something that I disagree with; I don't agree that we split at all (i.e. I reject evolution). However, that is not the point. I was not talking about where we came from, but how we are classified, and pointing out that there can be more than way to classify things. Do we classify according to percentage similarities of DNA, according to the existence or otherwise of a soul, or according to any number of other possible ways of classifying? And even that question is a bit pointless because you are not limited to classifying things according to only one classification system. That is, you could classify according to similarity of DNA '''and'' according to the existence of a soul. So you could then say that we are animals according to classification system A but not according to classification system B. It's a bit like the question of whether or not Pluto is a planet. Whether or not it's a planet depends on which classification system you are using, and astronomers recently decided to change which classification system they used. [[User:Philip J. Rayment|Philip J.
