Evolutionary history and fossil discoveries of hummingbirds.

Hummingbirds belong to the family Trochilidae, which is estimated to have originated around 22 million years ago 

Fossil discoveries provide insights into the early evolutionary history of hummingbirds.

Fossil evidence reveals early hummingbirds had similar adaptations to modern species

During the Miocene and Pliocene epochs (around 5-20 MYA), hummingbirds underwent significant diversification and spread across the Americas.

These adaptations allowed hummingbirds to exploit nectar resources and evolve unique pollination relationships with flowering plants.

Biogeographic events, such as continental drift and climate changes, influenced their evolutionary history and geographic distribution.

The fossil record and molecular phylogenetics indicate a diverse evolutionary lineage of hummingbirds
