The idea that chickens are the closest living relative of the Tyrannosaurus rex is a fascinating one. Chickens were the first bird to have their genome sequenced, which helped provide evidence that they are the closest living relative of the T-Rex. This discovery furthers the theory that birds evolved from dinosaurs and are, in fact, living dinosaurs. This idea is supported by the many similarities between chickens and the T-Rex, including walking on two legs, having scaly feet with sharp claws, and both having an arched neck with a big head.

What You'll Learn
Chickens are living relatives of dinosaurs
The link between chickens and dinosaurs was first suggested by anatomical similarities. Both chickens and T-Rex walk on two legs, have scaly feet with sharp claws, and both have an arched neck with a big head. Some dinosaurs even had feathers covering their bodies and bird-like lungs.
Molecular evidence has since been found to support this theory. In 2008, scientists performed a molecular analysis of a shred of 68-million-year-old Tyrannosaurus rex protein and compared it to a variety of proteins belonging to a host of different animals. They found that the T-Rex collagen was most similar to chickens and ostriches.
Chickens were the first bird to have their genome sequenced, which provided further evidence that they are the closest living relative of the T-Rex.
While birds are distinct from dinosaurs, they did descend from them and so it is not a stretch to call them modern dinosaurs.

T-Rex is closely related to chickens
The T-Rex is closely related to chickens. 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 proved to be most similar to chickens and ostriches.
Chickens are smart animals that have some pretty amazing characteristics that separate them from any other animal. For example, chickens aren’t completely flightless; they can get airborne to make it over a fence or a tree. These birds can distinguish more than 100 faces of people they see regularly and animals that they frequently interact with.
There are over 20 billion chickens on Earth, which is more than any other bird species. Over 8,000 years ago, chickens were domesticated in Southern China for their meat and eggs. Now, they are one of the most widespread domesticated agricultural animals and one of the most profitable.
Even before discovering the evidence from the fossil, some scientists observed that chickens and the T-Rex had similar characteristics. Both chickens and T-Rex walk on two legs, have scaly feet with sharp claws, and both have an arched neck with a big head. There was proof that some of these dinosaurs even had feathers covering their bodies and bird-like lungs.
This evolutionary proof furthers the theory that birds evolved from dinosaurs – and technically are living dinosaurs today!

Chickens descended from dinosaurs
Scientists have long believed that birds evolved from dinosaurs, and chickens were the first bird to have their genome sequenced, providing further evidence for this theory. The similarities between chickens and dinosaurs include walking on two legs, having scaly feet with sharp claws, and both having an arched neck with a big head. Some dinosaurs even had feathers covering their bodies, bird-like lungs, and bone structures similar to birds.
The idea that chickens are descended from dinosaurs was further supported by a 2004 study, in which an international team of geneticists produced a complete map of the chicken genome. This helped determine that chickens were not only the first domesticated animal but also the first bird and, consequently, the first descendant of dinosaurs.
Chickens have been domesticated for over 8,000 years, originally in Southern China for their meat and eggs. They are now one of the most widespread domesticated agricultural animals, with over 20 billion chickens on Earth. Americans consume around 8 billion chickens per year, making them more popular than beef.
While chickens are often overlooked as dim-witted or slow, they are actually quite smart and have some amazing characteristics that separate them from other animals. For example, they are the closest living relative of the T-Rex, a mighty and fearsome creature that once roamed the Earth.

Birds are modern-day dinosaurs
In 2004, an international team of geneticists sequenced the chicken genome, revealing that chickens are descendants of dinosaurs. This finding was further supported by a 2008 study where scientists compared the amino-acid sequence from T-Rex collagen to that of various modern species, including chickens. The results indicated that the T-Rex collagen was more similar to chicken collagen than to any other creature alive today.
The idea that birds are living dinosaurs is also supported by the observation that chickens share similar characteristics with the T-Rex. Both walk on two legs, have scaly feet with sharp claws, and possess an arched neck and a big head. Additionally, there is evidence that some dinosaurs had feathers, further reinforcing the link between birds and dinosaurs.
Birds, such as chickens, are classified as theropod dinosaurs. This classification includes powerful predators like the T-Rex and smaller dinosaurs like Velociraptors. While the T-Rex and Velociraptors may differ in size, birds like chickens can provide insight into the evolutionary history and characteristics of these dinosaurs.
The connection between birds and dinosaurs extends beyond chickens. For instance, ostriches have been found to be closely related to dinosaurs, particularly to the velociraptor due to their overall size, shape, and talons. This discovery highlights that the relationship between birds and dinosaurs is not limited to a single bird species but is a broader phenomenon.
In conclusion, the statement "Birds are modern-day dinosaurs" is supported by scientific evidence and research. Birds, including chickens and ostriches, are descendants of dinosaurs and share anatomical and genetic similarities with their ancient relatives. As our understanding of evolution and paleontology continues to evolve, we uncover more fascinating connections between the creatures of today and those that roamed the Earth millions of years ago.

Chickens are smarter than they seem
Chickens are often overlooked as dim-witted or slow animals, but recent studies have shown that they are smarter than they seem. Chickens have been documented to help other hens in need, performing actions such as leaving worms for blind hens to eat. They are also capable of basic math, with young chicks only a few days old able to perform simple arithmetic with numbers five and under. In addition, chickens have impressive memory capabilities, being able to remember up to 100 other chickens and recall specific individuals after months of separation. They can also remember human faces, which has allowed them to be trained as therapy animals.
Chickens also exhibit self-awareness, with scientists confirming that they possess advanced levels of self-assessment and self-control. They have a diverse vocabulary, with studies finding that they can make at least 24 distinct sounds, each in response to a specific situation. For example, when a chicken senses a predator in the sky, it will shriek to warn others, while the discovery of food elicits excited "dock dock" sounds. Roosters, in particular, are known to alert female chickens and chicks when predators are nearby but may remain silent if surrounded by other males.
Chickens are also capable of empathy, not only towards their offspring but also towards other members of their species. They can take the perspective of other birds, an ability previously seen in only a handful of species, including humans. Furthermore, chickens have been found to possess deceptive and cunning communication skills, on par with those of some primates. They use sophisticated signals to convey their intentions and may even withhold or distort information when doing so benefits them.
Chickens are the closest living relative of the Tyrannosaurus rex, or T-Rex, a meat-eating dinosaur. Both chickens and T-Rex walk on two legs, have scaly feet with sharp claws, and have arched necks with big heads. Some dinosaurs even had feathers covering their bodies, providing evidence that birds evolved from dinosaurs. Chickens, therefore, can be considered modern-day dinosaurs.
