🤔 Reflection Question

How did the dolphins even get to the Amazon rivers?
Hit reply — I’d love to hear your take.

Amazon river dolphins ended up inland because their marine ancestors became trapped when ancient sea levels dropped.

Millions of years ago, these dolphins did not actively swim up the river from the Atlantic Ocean as it exists today. Instead, during the Miocene epoch around 15 to 16 million years ago, exceptionally high global sea levels flooded large portions of low-lying South America. This massive marine incursion created a vast, shallow inland saltwater sea where the Amazon basin sits today. Ancient ocean-dwelling dolphins entered these warm, prey-rich waters, but as the millennia passed, global sea levels receded. Concurrently, the tectonic collision that raised the Andes Mountains radically altered South America's geography, draining the inland sea and slowly shifting the region into a freshwater system of lakes and rivers. Trapped inland, these dolphins adapted to the decreasing salinity over generations, evolving unfused neck vertebrae to turn their heads 90 degrees around submerged trees, paddle-like flippers for tight steering, and advanced echolocation to hunt in muddy waters.
