The standard theory of evolution is that animals that randomly inherited
genes that produced
beneficial traits — in the case of the giraffe, a longer neck, which made it easier to reach tall acacia trees — ate better, reproduced more often and passed these
gene variants to their offspring.
«We are the first to show a possible genetic connection in this respect,» said Dr. Amin, adding that this implies that such a therapy might be
beneficial for patients carrying risk
variants in the NKPD1
gene.
