This is just true by definition of the word “ancestor”
Not precisely humans but the ancient placental mammal lineage that includes humans, dogs, and bats.
Obviously. That’s how evolution works. Everything alive today had an “ancestor” alive at the time of the dinosaurs, and before the time of the dinosaurs.
I guess the Flintstones predicted this one...
I feel like the news is in the details here, that non-biologists won't really understand or appreciate. Because as far as I know it's not news that small mammals co-existed with dinosaurs.
I distinctly remember learning (as a kid) that mammals survived it because they were small, could breed often, and produced lots of offspring... so they could evolutionally adapt quickly.
How would we exist if they didn't?
If humans came from apes why are there still apes?
/s
If dogs come from wolves, why are there still wolves? Some things change during their lifecycles (like caterpillars to butterflies or tadpoles to frogs). Other things change between generations. Not everything in a classification has to change.
Did you miss the /s that I entered or did you forget your own?
I swear it didn't have a /s when I read it. Sorry.
