It seems unlikely that the mutation rate would actually increase. . Why? It's been know for a long time that the mutation rate in Bacteria increases with environmental stress, there are mechanisms triggered by stress. For instance error prone sigma factors (enzymes for DNA replication) are preferentially used which increase point mutations etc. In plants transposons (jumping genes) are activated by environmental stress and increase the mutation rate. Shapiro's theories aren't really that controversial except when creationists think he's talking about intelligent design. I've always thought that mutations were caused by radiation exposure that would create random alterations of dna. But perhaps I'm misinformed on that (as the sole or primary cause. I can see how lots of chemical environmental factors could be involved during replication, and maybe that's where most mutations happen anyway. |
