-Or 80% dog?
-Or 50% banana?
Actual reality may be a little more complex than high-school biology lead you to believe.
Check out the vid to see a few of the faults in the original theory.
A few of the mistakes MinuteEarth cites:
1) Chromosome count differences,
2) Duplications,
3) Deletions,
4) Single letter changes.
5) Moved, split, or inverted code-blocks,
6) And Exclusions of 1.3 Billion “Repeated” letters, Yikes!
So they say the remaining 2.4 Billion letters are 98.77% identical. -If we ignore 18% of the chimpanzee genome and 25% of ours!
But wait, it gets worse!
Over at Snopes & StackExchange, the picture gets even bleaker.
1) The users note that the areas tested, are likely Only The Protein-Coding Region of the genome.
2) Anywhere up to 95% of DNA is so-called “Junk DNA”, (although we had a post awhile back disputing that claim) so the part geneticists compared is probably closer to 5%, not 75-82%.
3) And then Terdon from StackExchange Biology notes that because of the way DNA makes proteins, the amount that actually goes anywhere and does anything is even smaller than that 5%.
-It’s more like 2%.
So when you add all that up, maybe we are very similar to bananas, dogs & chimpanzees.
-If you only consider a very small part of DNA that does very basic functions for many living things.
