Human DNA Shared With Other Things

Most of us have come a long way since the dark days when it was taught that God created all living things and made humans by piling up some dirt and blowing into it's nostril although there are some who will still argue that Adam and Eve was where it all began.
As unlikely as it seems, those people share 99.9% of the DNA with the rest of us which is only 3.9% more than we share with a Chimpanzee although their IQ's are much closer than that. 
We have known for a long time that we’re closely related to chimpanzees and other primates, but the National Human Genome Research Institute have a growing list of just how much genetic material we share with other things.
Gene sequencing reveals that although we are most closely related to primates, we are 95% identical to pigs, 90% to cats, 84% to dogs, 80% to cows, 75% identical to mice, 70% identical to worms, 69% to a platypus and 60% identical to a Chicken, Banana and a Fruit Fly which may make you think differently about that Ham sandwich you had for lunch.
Bees share 44% of human DNA and even a potato has 20% human in it which is almost half as much as a cabbage which shares 45% although the DNA of humans and lettuce is 16% identical.
It might be worth remembering the next time someone tries to question evolution or explain the fairness of our Capitalist system that of the 99.9% you are looking at, they are 46% cabbage and sometimes the percentages are higher, very much higher in the cases of Estate Agents, Insurance Salesmen and right wing politicians.
