I'm not entirely sure what you're asking, but I think the problem is that you are anthropomorphizing, projecting human qualities on a single cell. The ancient cell didn't "recognise" anything, it didn't have the capacity. What happened was, their were billions of random configurations of cells and the configuration that worked best was most successful. It crowded out all the other cell types, and then mutation caused a new random group of competitors to spring up with variations on the successful design. It is also not acurate to say a human cell, in this context. At the time when the individual cell was signifigant, humans were millions of years from existing.

I hope this is helpful.
