T. rex's closest living relative is not just chickens, but all birds

It is true that chickens are closely related to Tyrannosaurus rex. In 2003, a unique fossil of the T-Rex was discovered with soft tissue intact, allowing scientists to extract enough DNA for research. The proteins found in the DNA of the T-Rex were most like those of chickens. However, T. rex's closest living relative is not just chickens but all birds.

T. rex and chickens share similar characteristics. Both walk on two legs, have scaly feet with sharp claws, and both have an arched neck with a big head. There was also proof that some dinosaurs had feathers covering their bodies and bird-like lungs. However, these similarities are not unique to chickens.

T. rex and birds are united by the anatomy of their hips, features of their skulls, hollow bones, and the likelihood of being covered in some form of feathers. These traits adapted over time to fit different ways of life as each group separated from one another. While T. rex used the hollow air spaces in their bones as scaffolding to allow for bulkier bodies, ancient birds used them to lighten their load and take flight.

Molecular analysis of a shred of 68-million-year-old Tyrannosaurus rex protein confirms that dinosaurs share common ancestry with chickens, ostriches, and, to a lesser extent, alligators. Scientists have also determined that T. rex groups with birds better than any other organism, including modern reptiles.

Therefore, while chickens are closely related to T. rex, so are all other birds.

T. rex's collagen makeup is almost identical to that of a chicken

Chickens, ostriches, and other birds are the closest living relatives of the Tyrannosaurus rex. In 2003, a unique fossil of the T-Rex was discovered with soft tissue intact, allowing scientists to extract enough DNA for research. The proteins found in the DNA of the T-Rex were most like those of the chicken.

The T. rex's collagen makeup is almost identical to that of a chicken. Collagen is a structural protein that appears in slightly different forms in many animals. In 2007, scientists sequenced tiny pieces of collagen protein from T. rex fossils. They compared the collagen protein from several dozen species to place the T-rex on the animal kingdom's family tree. The T. rex's collagen proved to be most similar to chickens and ostriches.

The discovery of the link between T. rex and chickens provides the first molecular evidence that birds are the modern-day descendants of dinosaurs. It also overturns the long-held palaeontological assumption that delicate organic molecules such as DNA and proteins are completely destroyed during the fossilisation process.

While chickens are the closest living relative of the T. rex among all species in today's genome databases, it is important to note that all birds are equally closely related to the T. rex. This distinction is important for understanding the processes of evolution. The T. rex shared anatomical similarities with birds, such as two legs, hollow bones, and the likelihood of being covered in some form of feathers.

T. rex and chickens share anatomical similarities

Chickens and T. rex share a number of anatomical similarities. Firstly, both walk on two legs and have similar hip structures. Both have scaly feet with sharp claws, and both have arched necks with large heads. Some T. rex dinosaurs even had feathers covering their bodies and bird-like lungs.

The discovery of a unique T. rex fossil in 2003 with soft tissue intact allowed scientists to extract enough DNA for research. This 68-million-year-old fossil was compared to the DNA of 21 modern animal species, and the proteins found in the T. rex DNA were most like those of the chicken.

Further evidence comes from the analysis of collagen, the main protein found in bone. The T. rex collagen makeup was found to be almost identical to that of a modern chicken. This provides molecular evidence for the notion that birds are the modern-day descendants of dinosaurs.

However, it is important to note that while chickens are closely related to T. rex, they are not the only living relative. All birds are equally closely related to T. rex, including ostriches, hawks, hummingbirds, and parrots.

Tyrannosaurus rex, the superstar of paleontology, has been the subject of renewed interest in popular culture. With the success of films like Jurassic World and TV series like Primal and Prehistoric Planet, the T. rex continues to captivate imaginations. Amidst this surge in popularity, a fascinating question has emerged: Is the chicken, a common poultry bird, the closest living relative of the mighty T. rex?

The short answer is a resounding yes! Research published in Science and reported in the New York Times revealed that the closest living relatives of Tyrannosaurus rex are birds, including chickens and ostriches. This conclusion was based on molecular evidence, specifically the comparison of collagen, a structural protein found in various animals. The T. rex collagen showed the greatest similarity to chickens and ostriches, followed by alligators. This discovery provided the first molecular proof of the long-suspected link between dinosaurs and birds.

To understand this relationship, we must explore their evolutionary histories. Both Tyrannosaurus and Paraves, a clade of dinosaurs that includes birds and Velociraptor, are theropods, characterized by their two-legged, meat-eating nature. This group also includes famous dinosaurs like Dilophosaurus and Spinosaurus. These reptiles share anatomical features such as hollow bones, skull structures, and the likelihood of feather coverage. Over time, these traits adapted to different lifestyles as the groups diverged. While T. rex utilized its hollow bones to support a bulky body, ancient birds took flight, using their hollow bones for lift.

The distinction between T. rex and other hulking predators like Giganotosaurus further highlights the unique relationship with birds. T. rex belongs to one of the three main branches of the dinosaur family tree, setting it apart from similar giant theropods like Giganotosaurus. This diversity within the dinosaur kingdom underscores the close evolutionary ties between T. rex and birds.

While the idea of a chicken being the closest living relative of T. rex may seem amusing, it holds significant implications for our understanding of evolution. By studying the evolutionary paths of these creatures, we gain insights into the processes that shaped their development and the broader context of life on our planet. So, the next time you see a chicken, remember that it's not just a barnyard bird but a living reminder of the incredible journey of life on Earth.

T. rex and chickens are theropods, meaning two-legged, meat-eating dinosaurs

Tyrannosaurus rex and chickens are indeed theropods, meaning two-legged, meat-eating dinosaurs.

Theropods were a group of dinosaurs that walked on two legs and had meat-based diets. They are characterised by their hip anatomy, skull features, hollow bones, and the likelihood of having feathers. This group includes dinosaurs like the Dilophosaurus and Spinosaurus, as well as the Tyrannosaurus rex.

While the idea of birds being related to dinosaurs was first popularised by the movie Jurassic Park, it has since been supported by scientific research. In 2003, paleontologists discovered a unique T. rex fossil with soft tissue intact, allowing them to extract and analyse DNA. By comparing the T. rex DNA to that of 21 modern animal species, they found that the proteins in the dinosaur's DNA were most similar to those of chickens. This provided the first molecular evidence of the evolutionary link between dinosaurs and birds.

However, it is important to note that chickens are not the only living descendants of dinosaurs. All birds, including ostriches, hawks, hummingbirds, and parrots, share this distinction. Additionally, other bird-like dinosaurs, such as Velociraptors, are also closely related to T. rex.

The discovery of molecular evidence has opened up new avenues of research in palaeontology, allowing scientists to build more accurate evolutionary family trees and gain a deeper understanding of the processes of evolution.
