Harvard researcher explores the evolutionary bond between hummingbirds and red flowers

In the forests and gardens of the Americas, a Harvard researcher named Patrick McKenzie has turned his attention to one of evolution's quieter masterpieces: the bond between hummingbirds and red flowers. What looks like a bird simply feeding is, in truth, a millions-of-years-old conversation between two species, each having shaped the other through the patient pressure of survival. McKenzie's work reminds us that beauty in nature is rarely ornamental — it is functional, reciprocal, and deeply fragile.
