F2F Class Notes 13th January (Raph)[W]

Original:

Bees are always considered as the diligent farmers in Nature,but they’re not the only animals who pollinate plants.
Many bats have a sweet tooth and they would be killed for a sugary nectar. What’s interesting is that most plants are offering them a more dilute juice rather than a sweeter and more attractive one. That’s weird, over time should nectar evolve to be exceptionally sweet in order to produce more offspring. But it hasn’t. Why?
To seek the answer, scientists spent more than six years in the Costa Rican rainforest experimenting with artificial flowers and bats fitted with radio tags. The extraordinary thing is that they even made those flowers evolved.
