The earliest angiosperms appeared in the Cretaceous. This is after the appearance of Hymenoptera (Jurassic) and Diptera (Triassic). While a nice story, this needs additional substantiation. An alternative explanation is likelier imo.
Right, the whole point of bees as insect pollinators (reflecting that they are recent evolutionary line) is that they are by a healthy margin the most intelligent arthropod. They will inspect then successfully pollinate anything floral over a wide geographic range. Most insect pollinators are instinctually tied to certain species/families.
Thanks, I never thought about bees like that. They certainly can use many types of flowers, as evidenced by various sorts of honey. Nitpick: some spiders are pretty darn intelligent and even seem to dream when they sleep, apparently.
Or perhaps all of your thousands of children being in peril, having found themselves on a murderous human, with no obvious path to escape as the gigantic scary human swaths hundreds at a time?
My magnolia is the only thing that seems to attract honeybees, which I rarely see otherwise. The article doesn't seem to justify the "not bees" part, though. I'd imagine bees can pollinate them too.
