Over time, humans have domesticated various animals to better suit our needs. Everything from dogs to pigs to chickens were bred to serve as companions or to feed an entire family for dinner. If we look at the history of domestication, goats were most likely the first animals to be domesticated in ancient Mesopotamia. Sheep and chickens came next, followed by larger animals like oxen and horses, which were used for hard labor like plowing. When you take a bite of steak or munch on a turkey drumstick, you probably don't think about the animal it came from. We've been eating animals for millennia, but generations of breeding have given rise to farm animals that look pretty different from their wild ancestors. The way some animals look today is very different to the way they looked before people started selectively breeding them. From <a href="https://rumble.com/v488tt-turkey-talker.html" target="_blank">turkeys</a> and chickens to cows and sheep, the video shows some of the most common animals we eat looked in the past versus today. Over many generations, humans have domesticated wild animals in the same way we created dogs out of wolves. We have selectively bred some ship that are so fluffy. They could overheat and die without a haircut, chickens that are so large they can feed an entire family and <a href="https://rumble.com/v4fh1j-excited-cows-enjoy-playing-in-hay.html" target="_blank">cows</a> so udderly huge that can feed an entire village. We have created big pink pigs that make bacon possible, and of course, (slightly) less ferocious cats that can break the Internet. Which animals might we domesticate next?

Scientists have identified more than 400 shark species but there is still so much we don’t know about these magnificent animals. One species, in particular, is a source of wonder for many researchers: the Greenland Shark or Somniosus microcephalus. Greenland sharks are among the world’s largest predatory sharks, growing up to 6 meters in length. Because of their habitat in cold dark waters, there is still so much that scientists are yet to discover about the sharks. Greenland sharks live in the cold dark waters of the Arctic and have long been a mystery to the science community. Scientists that are studying them, suggest that these <a href="https://rumble.com/v3obkd-baby-great-white-shark-washes-up-on-sydneys-manly-beach.html" target="_blank">sharks</a> can live up to six centuries old. Sharks are some of the most fascinating creatures on the planet. They have been swimming in our oceans and seas for hundreds of millions of years. One question that kept burning away at scientists was just how old are these slow-moving creatures? Researchers from the universities of Copenhagen and Manchester sailed in treacherous waters to study <a href="https://rumble.com/v4hfn7-scientists-capture-rare-greenland-shark-on-video.html" target="_blank">Greenland sharks</a>, which can live for over 400 years. Little is known about this type of shark, but they are known to be scavengers and predators as they have been observed feeding on seals, and have been found with polar bear remains in their stomachs. The researchers took samples and satellite tagged the sharks, in order to find out more about their hearts and diet, their movement and reproductive patterns. Initial data recorder their heart beating once every ten seconds. By studying more data from the expedition they hope to learn about diseases associated with the aging process, in the hope of developing new therapies for humans in the future.
