Humans share almost all of our DNA with cats, cattle and mice
More than half of our genetic code is the same as a banana's
Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Our bodies have 3 billion genetic building blocks, or base pairs, that make us who we are.
And of those 3 billion base pairs, only a tiny amount are unique to us, making us about 99.9 per cent genetically similar to the next human.
A recent TED talk by physicist and entrepreneur Riccardo Sabatini demonstrated that a printed version of your entire genetic code would occupy some 262,000 pages, or 175 large books. Of those pages, just about 500 would be unique to us.
This is because large chunks of our genome perform similar functions across the animal kingdom.
Take a look at how genetically similar we are to everything around us:
Humans are 99.9 per cent similar to the person sitting next to us. The rest of those genes tell us everything from our eye colour to whether we're predisposed to certain diseases.
A 2005 study found that chimpanzees — our closest living evolutionary relatives — are 96 per cent genetically similar to humans.
Cats are more like us than you'd think. A 2007 study found that about 90 per cent of the genes in the Abyssinian domestic cat are similar to humans.
When it comes to protein-encoding genes, mice are 85 per cent similar to humans. For non-coding genes, it is only about 50 per cent. The National Human Genome Research Institute attributes this similarity to a shared ancestor about 80 million years ago.
Domesticated cattle share about 80 per cent of their genes with humans, according to a 2009 report in the journal Science.
When it comes to insects' DNA, humans have a bit less in common. For example, fruit flies share 61 per cent of disease-causing genes with humans, which was important when Nasa studied the bugs to learn more about what space travel might do to your genes.
And while the egg-laying and feathered body are pretty different from a human's, about 60 per cent of chicken genes have a human gene counterpart.
Even bananas surprisingly still share about 60 per cent of the same DNA as humans.
