The relationship between chickens and T-Rex dinosaurs has been a topic of fascination for many. While chickens are often considered the closest living relative of the T-Rex, this assertion has been challenged. All birds are technically equally related to the T-Rex, as they share the same most recent common ancestor. However, some similarities between chickens and T-Rexes have been observed, such as walking on two legs, having scaly feet with sharp claws, and an arched neck with a big head. Additionally, some T-Rexes may have had feathers and bird-like lungs. The discovery of a unique T-Rex fossil in 2003 allowed scientists to extract and compare DNA, finding that the proteins in T-Rex DNA were most similar to those of chickens. This discovery provided further evidence for the theory that birds evolved from dinosaurs and are technically living dinosaurs today.

What You'll Learn
Chickens are the closest living relative to T-Rex
Chickens are often touted as the closest living relative of the Tyrannosaurus rex. This claim is based on research published in 2013 that compared the collagen, a structural protein, of a 68-million-year-old T-Rex fossil to that of 21 living animal species. The T-Rex collagen proved to be most similar to chickens, followed by ostriches and alligators.
However, the idea that chickens are the closest living relative of the T-Rex is not universally accepted. Some sources argue that while chickens are related to the T-Rex, they are not its closest living relative. They contend that all birds are equally related to the T-Rex, and singling out chickens is akin to claiming that one sibling is closer to a parent than the others.
Despite the ongoing debate, it is undeniable that chickens and T-Rex share some striking similarities. Both walk on two legs, have scaly feet with sharp claws, and possess an arched neck and a large head. Additionally, some dinosaurs had feathers and bird-like lungs, further bolstering the theory that birds evolved from dinosaurs and are technically living dinosaurs today.
The discovery of the T-Rex fossil with preserved soft tissue in 2003 provided valuable molecular evidence about dinosaurs, which were previously believed to be cold-blooded and slow-moving reptiles. This find, coupled with anatomical similarities, strengthened the argument for the dinosaurian origins of birds.
In conclusion, while the claim that "chickens are the closest living relative to T-Rex" may be an oversimplification, it is undeniable that chickens and T-Rex share a significant evolutionary history and that our understanding of their relationship continues to evolve as new evidence comes to light.

T-Rex and chickens share anatomical similarities
The link between chickens and the Tyrannosaurus rex has intrigued people for years. While it may seem absurd to some, chickens and T-Rex share many anatomical similarities.
Chickens and T-Rex have a unique body plan visible in their skeletons. They both have a skull attached to a spine, ribs, and two legs with splayed toes. The appendicular skeleton of both species is S-shaped. While birds lack teeth and long tails, the genes to manipulate these features still exist in the gene sequence of birds. In 2006, researchers at the University of Wisconsin published a report on manipulating the genes responsible for teeth in chicken egg embryos, resulting in buds that would later develop into crocodile-like teeth.
Birds, including chickens, are a type of theropod rooted in the dinosaur family tree. They share the same ferocious meat-eating characteristics as the T-Rex and Velociraptor. Birds lie within an advanced group of theropods called parades, a subgroup that evolved from the brute body plan of their gargantuan ancestors into larger brains, sharpened acute senses, and smaller, lighter bodies.
The link between T-Rex and birds was suspected for many years based on anatomical similarities. In 2013, researchers provided the first molecular evidence of this link. They compared the molecules of collagen, a structural protein, from T-Rex remains with those of 21 living animals, including chickens. The results showed that T-Rex collagen was most similar to chickens and ostriches.
While the T-Rex and chickens share many similarities, it is important to note that they are not directly related. The lineage that resulted in the T-Rex split from birds about 160 million years ago, and birds had another 66 million years of evolution before chickens emerged. Thus, all birds are equally distant relatives of the T-Rex.

Chickens are smart and can perform basic arithmetic
Chickens are considered to be highly intelligent animals, with abilities such as manipulation, counting, empathy, and even basic mathematics. They are adept communicators, using a combination of sounds and body language to convey the significance of an event and elicit a specific response. For example, they have different warning calls for aerial and ground-based predators and can even \"name\" their owners. Research has also shown that chickens have deep empathy for their chicks and can sense when their young are in danger.
The notion that chickens are closely related to the Tyrannosaurus rex (T-Rex) is intriguing. According to some sources, the closest living relatives of the T-Rex are birds such as chickens and ostriches. This conclusion is based on anatomical similarities and molecular evidence, particularly the comparison of collagen molecules. However, it's important to note that the lineage that resulted in the T-Rex split from birds about 160 million years ago, and birds had another 66 million years of evolution before chickens emerged.
While it may be surprising to think of chickens as related to the mighty T-Rex, it's important to understand that evolution does not move backward. The T-Rex went extinct because it could not survive, while the chicken's ancestors were able to adapt and thrive. Chickens have survived and spread worldwide, showcasing their intelligence and adaptability.
Moving on to the mathematical abilities of chickens, studies have revealed that they possess a sophisticated awareness of numbers and mathematics. For instance, a 2017 study demonstrated that chickens can add, subtract, compare data sets, and count from left to right. Additionally, newborn chicks have been found to excel in simple shell games, indicating their ability to track objects and understand object permanence. These skills are not limited to chickens; other birds, such as ravens, crows, and parrots, are also known for their intelligence.
In conclusion, chickens are indeed smart and capable of performing basic arithmetic. They have complex cognitive abilities, including reasoning, communication, and empathy. Their mathematical skills, as demonstrated in various studies, showcase their understanding of numbers and problem-solving abilities. This knowledge about chicken intelligence contributes to our understanding of brains and behaviour in the animal kingdom, challenging stereotypes and broadening our perspective on the capabilities of different species.

T-Rex and chickens share a common ancestor from 200 million years ago
It is believed that chickens and T-Rex share a common ancestor from around 200 million years ago. The T-Rex and birds alive at that time were separated by almost 100 million years of divergent evolution, and then birds evolved for another 66 million years until chickens emerged.
The T-Rex is thought to have links to modern-day birds, with molecular analysis providing evidence of shared ancestry with chickens and ostriches. This analysis was performed on a shred of 68-million-year-old Tyrannosaurus rex protein, along with samples from 21 modern species. The T-Rex's collagen was found to be most similar to that of chickens and ostriches, with the closest match after that being alligators.
The discovery of this molecular evidence was made in 2003 by scientists Jack Horner and Mary Schweitzer, who found some unfossilized material inside a T-Rex bone. They broke the giant femur in half to transport it out of a remote field site in Montana by helicopter. While they were unable to recover any DNA, they did find molecules of collagen, a structural protein that appears in many animals.
This research provides the first molecular evidence of the evolutionary links between dinosaurs and birds, which had long been suspected due to anatomical similarities. The dinosaur-ness of birds had previously been popularized by the movie Jurassic Park, which depicted dinosaurs as quick, smart, and birdlike. However, the idea that dinosaurs were birdlike was first proposed in the 1970s by paleontologist Robert Bakker in his book "The Dinosaur Heresies."

T-Rex collagen is most similar to chickens and ostriches
The Tyrannosaurus Rex, or T-Rex, is one of the most well-known dinosaurs, largely due to its depiction in the Jurassic Park film franchise. For decades, dinosaurs were thought to be large, cold-blooded, slow-moving, and dim-witted reptiles. However, the idea of dinosaurs as quick, intelligent, and birdlike gained popularity following the release of Jurassic Park, reflecting proposals made by paleontologist Robert Bakker in the 1970s.
The link between dinosaurs and birds has long been suspected based on anatomical similarities. In 2005, Mary H. Schweitzer of North Carolina State University discovered soft-tissue preservation in a T-Rex bone, allowing for the analysis of collagen protein. Collagen is a structural protein that appears in slightly different forms in many animals. By comparing the dinosaur collagen with that of 21 living animals, including humans, chimps, mice, chickens, ostriches, alligators, and salmon, researchers were able to determine that T-Rex collagen is most similar to chickens and ostriches.
This finding provides the first molecular evidence of the evolutionary relationship between dinosaurs and birds, placing the T-Rex on the phylogenetic tree between alligators and chickens and ostriches. While chickens and ostriches are only distantly related to each other, this research confirms that dinosaurs share common ancestry with these birds. According to John M. Asara, director of the mass spectrometry core facility at Beth Israel Deaconess Medical Center and an instructor in pathology at Harvard Medical School, "We determined that T. rex, in fact, grouped with birds -- ostrich and chicken -- better than any other organism we studied. We also show that it groups better with birds than modern reptiles, such as alligators and green anole lizards."
While it is fascinating to consider the link between T-Rex and chickens, it is important to note that the lineage that resulted in the T-Rex split from the lineage that led to birds about 160 million years ago. Following this divergence, birds evolved for another 66 million years before chickens emerged. Therefore, while chickens may be the closest living relative of the T-Rex among extant birds, they are still quite distantly related, and the T-Rex's closest relatives during its time would have been other dinosaurs.
