Sharks more genetically similar to humans than to zebrafish

The first large-scale exploration of the genetic code of the great white shark has revealed some unexpected insights into what makes the iconic apex predator so distinctive.

Although the researchers expected to the proportion of the white shark’s gene products associated with metabolism to be greater than humans’ or zebrafishes’, it turns out there are fewer differences than they expected, which the researchers said was a surprise considering boney fish like the zebrafish are much more closely related to the white shark than humans.

Researchers were also surprised to find that the transcriptomes in the white shark’s heart showed greater genetic similarity to humans than zebrafish.

The results raised more questions than provided answers.
