The most important remaining secret at present is exactly what happened to hummingbirds during the approximately 25 million a long time among the primitive Eurotrochilus and the modern fossils. The astounding morphological adaptations, the decrease in dimension, as well as dispersal for the Americas and extinction in Eurasia all occurred through this timespan.
