How do we know that the genes have changed so much? I assume we don't have any 200 million year old ginkgo dna bc fossils are rocks, right? Is there another way to tell?

Being polyploid is pretty normal 🙂
Love you Hank 👍🏼
meanwhile humans look all sorts of different ways since H. erectus, but there is absolutely no evidence of speciation since then.
we fill the same ecological niche, have the same habitat and range, and all populations can interbreed and apparently always have been able to.
Takes a lot of work to look that good for that long.
Why was my immediate thought Kabuto -> Kabutops in Pokemon 💀. I was like “yeah, of course they do” not realizing this was a SciShow video cuz im tired af and its 3 in the morning
I started my run of shorts with a video from John, I'll finish with one of Hanks.
I love learning stuff like this 😀
Just like my uncle
As long as parasites evolve, hosts will follow
Maybe they should have worked on not smelling like puke lol
(my college campus had tons of ginkgo trees and I'm still bitter about it)
Ginko trees are the Pokémon players that only use aesthetically pleasing Pokémon, and yet still win some how.
Tfw i step on a ginko leaf and is shot into a tank containing a very expensive south American turtle only to then be put back exactly where I stood before, not noticing a thing.
Those tree’s stink so bad. I had one outside of my school and when you stepped in their little seed pods your shoes smelled like vomit all day
So they got the morphology DOWN on the first try! Congrats, Ginkos!
What makes the different enough to be considered evolving
There was one at my elementary school and I thought it was so cool
Everything is the same as it was when it was created, Just FYI.
What about the Coelacanth?
gingko trees are so freaking cool. one of these days I'm gonna get a tattoo that incorporates them into the design, was thinking a chest piece
If their evolution went the same path as the Chevy Blazer then the old ones are better
Probably the same with animals like sharks and crocs/gators, they look the same or similar to how they would have millions of years ago but I’d guess some stuff has changed even if it’s small ways
So ginko didn't evolve in shape and maybe that's why it's good for memory
So many living fossils kind of makes fossils look bad.
If i could figure out how i would save this for next time i debate a creationists. Man i hate the implementation on these shorts. Skip 10 seconds by double clicking? Nah man you can't fast forward or rewind, double click is to like on these.
By the very fact that they still exist and the conditions then were significantly different from now it is clear they have evolved.
Ever since I learned about them in 2nd grade, Ginkos have been my go-to favorite tree. The one we studied in the garden was blooming, even though wikipedia said that they were a non-flowering plant. My teacher told me to write it down as a flowering plant, and I learned a valuable lesson about source material that day.
Shakedown street
In nature, you have to run as fast as you can to stay in the same place. This tree has been running for 200 million years.
Why change perfection
Did the female form smell like dog poop in the distant past? Doesn’t seem effective from an evolutionary standpoint.
