Problem:

I'm not sure if this is actually a philosophical question, but I was reading a timeline of life on earth and I came to this:
4500-3500 Ma The earliest life appears, possibly at Alkaline vents with the creation of the Last Universal Common Ancestor, possibly derived from self-reproducing RNA molecules.[6][7] The replication of these organisms requires resources like energy, space, and smaller building blocks, which soon become limited, resulting in competition, with natural selection favouring those molecules which are more efficient at replication. DNA molecules then take over as the main replicators and these archaic genomes soon develop inside enclosing membranes which provide a stable physical and chemical environment conducive to their replication: proto-cells.
..and I thought to myself, are we still essentially doing that as we live our lives? I think I'm trying to connect the idea of a human "being competitive" with "evolution".. is there any truth to that? If yes, then justify it.
