Evidence Found In Ancient Cave "Hotel" Indicates Humans May Have Arrived In The Americas 30,000 Years Ago
The lack of clues left behind by ancient Americans has made it difficult for researchers to pinpoint precisely when humans first arrived on the continent. However, it has always been believed to be about 13,000 years ago, just as the world was thawing from the last ice age. Now, evidence from the Chiquihuite Cave in Zacatecas, Central Mexico, seems to suggest that prehistoric humans may have been living in North America as early as 30,000 years ago.Read news articleWhite-Throated Sparrows Across Canada Are Whistling A Catchy New Tune
Male birds typically sing the same tunes as the rest of their species because an unrecognizable song defeats the two primary reasons for their crooning — to establish and defend their territory and to attract mates. While the songs, which are passed down from generation to generation, may vary slightly by region, any new compositions are typically limited to the local environment. However, for reasons unknown to scientists, white-throated sparrows across Canada are abandoning their classic song for a catchy new tune "written" by their peers in British Columbia.Read news articleScientists Get Ready To Explore A 425-Foot-Deep "Blue Hole" Off Florida's Gulf Coast
Scattered across the ocean bed, and often hidden from the human eye, are hundreds, or perhaps even thousands, of "blue holes."

The term "bird brain" is frequently used to describe a person's lack of intelligence and good decision-making ability. However, some scientists believe it should be considered a compliment, given that many birds can perform tasks that were once considered solely within the realm of humans. These include manufacturing and using tools, solving problems, and planning for future needs. Now, Griffin, an African Grey parrot, has proved that birds may even possess better visual memories than human adults and children.Read news articleDogs Could Soon Become Valuable Allies In The Fight Against COVID-19
