Plot twist: scientists tried to crack the code behind great white shark populations, but ended up even more confused! Turns out, their nuclear DNA is super similar worldwide, but their mitochondrial DNA is totally different depending on where they live. Old theories about shark migration and breeding don’t explain it, and now researchers are basically stumped. There are only about 20,000 great whites left, and their genetics are keeping everyone guessing. Who knew sharks could be so mysterious? #Science #GreatWhiteShark #ScienceMystery
