That is not correct actually. Hobbiests have been in the forefront of SNP
discovery. Just using my own haplogroup, first a hobbiest brought what came
to be S28 / U152 and S21 / U106 as well as S29 to the attention of Jim
Wilson and others by sifting through the Perlgen dataset. Then S139 / L2
and and S144 / L20 emerged via sharp eyed hobbiests looking at the raw data
from 23andMe as presented in Adriano Squecco's charts. Who knows how long
it would have been if we had relied on the efforts of academic population
geneticists most of whom are still publishing data no more deeply genotyped
than M269 - universal to all of the above. This is the tip of the iceberg
of discovery in the past 4 years. Where were the "pros" during this
interval - how many SNPs can they claim to have discovered - a paltry few by

David. K. Faux.
