A Lesson in Survival

In the day-to-day grind of the animal kingdom, a myriad of adverse conditions, coupled with predictable predators, gives the term “survival of the fittest” a whole new meaning. Take the wily woodpecker. In this edition of SciShow, Hank Green points out that woodpeckers pummel their beaks against solid objects about 12,000 times a day at brute force. How do these amazing creatures of nature not sustain brain damage? “For one, they have built-in shock absorbers,” says Green. “They’ve also got their tongues. Woodpecker tongues wrap all the way around the skull, going up the back and over the top, fitting snugly into one end of the hyoid bone.”

Scientists now have the technology to bring animals back from extinction … sort of,” according to Hank Green of SciShow.
