AI Thread Summary
Scientists have identified two new dinosaur species from fossils discovered in Antarctica, dating back millions of years when the region was a warm, lush environment akin to the Pacific Northwest. One species is a 70-million-year-old, bipedal carnivore, related to velociraptors, while the other is a 190-million-year-old, quadrupedal herbivore, an early ancestor of large plant-eating dinosaurs like Diplodocus. The fossils were unearthed at two separate sites, located 2,000 miles apart, within a span of six days in December. The discussion also touches on the geological history of Antarctica, highlighting its past as part of a supercontinent and the ongoing processes of plate tectonics that continue to shape the Earth's continents.

WASHINGTON -- Scientists have discovered the fossils of two new species of dinosaurs that lived in Antarctica millions of years ago when it was a warm, green land similar to today's Pacific Northwest.

One creature from this lost world was a 70-million-year-old, two-legged meat-eater, a larger relative of velociraptors.

The other bones came from a 190-million-year-old, four-legged vegetarian, an early version of the huge, plant-eating monsters such as Diplodocus.

These relics from the Age of Dinosaurs were found at two locations, 2,000 miles apart, within six days in December.

And your point is?

The ! on your post seems to indicate astonishment... if so you might want to research the science of plate tectonics and discover that the continent of Antarctica (and all others) was once part of a single continent which over geologic time has broken apart into the continents we see now. The break-up continues today (see the mid Atlantic rift for example).

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
