"Although scientists analyzing blood and liver tissue from human cadavers had previously noted the postmortem activity of a few genes, Noble and colleagues systematically evaluated more than 1000. The team measured which of these genes were functioning in tissues from recently deceased mice and zebrafish, tracking changes for 4 days in the fish and 2 days in the rodents."

"What’s jaw-dropping is that developmental genes are turned on after death,” Noble says. These genes normally help sculpt the embryo, but they aren’t needed after birth. One possible explanation for their postmortem reawakening, the researchers say, is that cellular conditions in newly dead corpses resemble those in embryos."

Don't tell me that you are surprised! My response:
