Roses evolved 35 million years ago. We know because we've found fossils!
There are about 150 species of rose, growing all across the Northern Hemisphere, and humans have been growing them for about 5000 years. The practice probably started in Ancient China, before spreading to Ancient Persia, where damask roses were first bred – named after the city of Damascus in Syria.
The Persians also first developed methods for obtaining rose water and rose absolute, for flavourings and fragrances.
@InvaderXan what is the scale on that ruler, do you think? mm or cm..? I'm imagining it to be cm and that it's a MONSTER THORN could you imagine the size of the associated plant and flowers?! aaaaaaahhhh 😍
Haha! Sadly, I think it's mm. But I kinda love the idea of an ENORMOUS MONSTER ROSE! 😄
@InvaderXan Is that what the thorns are for?! I always assumed they were for self-defence. That's pretty cool.
@erbridge A bit of both, really. They definitely keep animals from eating them, but they also have that slightly hooked shape so their stems can catch hold of things to grow along. Same with related species like raspberries and blackberries.
Apples, on the other hand, are free standing trees. They don't need to climb, and their softer shoots need no defences because they're out of reach of small, nibbling animals.
I suspect some of the free standing rose cultivars humans have bred, if left alone for evolution to do its thing, would eventually lose their thorns too.
@InvaderXan I guess hearts where broken million of years ago too.
Sadly, that's harder to trace in the fossil record...
@InvaderXan rose,,, absoLUTE
@InvaderXan ughh so cool, thanks for sharing this! This is a quality post
I'm glad you liked it! ❤️
@InvaderXan All those years, and still not a blue rose in sight.
No, turns out, they never evolved the genes to produce any blue pigments.
@InvaderXan Nothing CRISPR can't fix.
