Summary Of Tweak In Gene Expression

The article “Tweak in Gene Expression May Have Helped Humans Walk Upright” found on Science Daily discusses work conducted by researchers at the Stanford University School of Medicine and at the HudsonAlpha Institute for Biotechnology. These researchers have been able to distinguish what gave us humans the ability to walk upright through research conducted on the fish threespine stickleback. The fish has evolved multiple times over time in order to match different environments around the world. David Kingsley, professor at Stanford University, believes that changes in gene expression levels of bone morphogenetic molecules are partly why we have evolved from having a chimp like hind food to being able to walk upright on two legs.
