Hey weird question, you know humans are all different

[LaurieFairyCake]

Facially (and obviously everywhere else)

Are animals the same amount of different?

So if you lined up a 100 Pugs or Puffer fish and got AI to pick out the differences (definitely AI as I couldn't tell one puffer fish from the other - clearly I have species blindness ) would they be AS DIFFERENT as humans ?

Birds see uv. If you google crow under uv, they have patterns. They might be identical patterns or there might be enough variations to see the difference if you are all crows together. We are sort of just guessing what animals see.

very interesting question - you should send it is to CrowdScience. They investigate all sorts of things like this with experts from round the world. https://www.bbc.co.uk/programmes/p04d42rc

I’m sure I recall reading that humans have stripes in certain light conditions and you can see it more on women when they are pregnant, or something.

@BiscuitlyBoyle yes people are stripey. It's one of my sons favourite facts after he got shingles which runs in stripes. I'm not sure how visible they are, but maybe to some animals they really show.

There was a farmer who had a stroke and could no longer recognise members of his family (not that uncommon in fact) but also his sheep.

This. My cat is a pedigree and I could easily believe that half the photos I see online of cats her breed and colour are her.

Oh wow, I never knew this 😮 that makes sense then.

I have read that sheep and cows have a 'best friend',so I would imagine that they can tell the difference.

I was at uni with two identical girls. They were on similar courses but the same uni. They had a pact to just nod and smile if someone said hello to the other one. This got confusing when one broke her leg.
They were triplets but the other girl wasn't identical. She went to another uni and did an entirely different course (e.g. identical A did Italian, identical B did French, non ID C dic engineering)

Learned in Borneo at the Sepilok Orangutan sanctuary: Humans have one of the wider range of facial variations amongst all species, and Orangs have a wider range than humans (despite their sadly low count). So that's info from a primate scientist :)

We had a dozen chickens once. Never imagined they could all look slightly different and I could tell the difference..same breed /size /colour. Have similar amount of dc.. Easy to tell apart. Some are loud. And some are very loud....
