What You'll Learn
- Molecular analysis confirms the evolutionary link between T. Rex and birds
- T. Rex and chickens share similar characteristics, such as two legs and scaly feet

Molecular analysis confirms the evolutionary link between T. Rex and birds
The fossil femur was discovered in a barren fossil-rich stretch of land spanning Wyoming and Montana. The collagen protein was sequenced using mass spectrometry techniques, which can sequence minute amounts of protein. This analysis revealed that T. Rex shares common ancestry with chickens, ostriches, and to a lesser extent, alligators.
The findings provide molecular evidence for the evolutionary relationships of non-avian dinosaurs and support the hypothesis that birds are dinosaurs' closest living relatives. This hypothesis had previously been based on morphological similarities in bird and dinosaur skeletons. The analysis also revealed that T. Rex groups better with birds than with modern reptiles, such as alligators and green anole lizards.
While the findings suggest that chickens are the closest living relative of T. Rex, some sources argue that this is misleading. All birds alive today are equally the closest relative of T. Rex, as they share a common ancestor. Additionally, the lineage that resulted in T. Rex split from the lineage that led to birds about 160 million years ago, and there were almost 100 million years of divergent evolution before birds had another 66 million years of evolution, resulting in chickens.

T. Rex and chickens share similar characteristics, such as two legs and scaly feet
It may seem absurd, but chickens are indeed the closest living relatives of the Tyrannosaurus rex. This claim is supported by molecular analysis of a shred of 68-million-year-old Tyrannosaurus rex protein, which was compared to that of 21 modern species. The results showed that chickens and T. rex share similar characteristics, such as two legs and scaly feet.
The idea that chickens are closely related to T. rex may seem far-fetched, but it is worth noting that all birds are equally related to this ancient dinosaur. In other words, if we were to trace back the evolutionary history of any bird species alive today, they would all lead back to the same common ancestor as T. rex. This is because birds are a type of dinosaur themselves, specifically a group called theropods, which also includes other meat-eating dinosaurs like Velociraptor.
While it is true that all birds are equally related to T. rex, it is important to note that chickens share some striking similarities with this ancient creature. In addition to having two legs and scaly feet, chickens and T. rex both have an arched neck with a big head. Furthermore, some evidence suggests that certain dinosaurs had feathers covering their bodies and bird-like lungs. These similarities provide further support for the evolutionary link between chickens and T. rex.
The discovery of the link between chickens and T. rex has revolutionized our understanding of dinosaur evolution. For decades, dinosaurs were believed to be cold-blooded, slow-moving, and dim-witted reptiles. However, with the discovery of this link, it became clear that dinosaurs were more closely related to birds and were likely quick, smart, and birdlike. This new understanding of dinosaurs has not only changed the way we view these ancient creatures but has also provided valuable insights into the processes of evolution and the diverse paths that different species can take.
In conclusion, the statement that "T. rex's closest living relative is a chicken" is technically true and supported by molecular evidence. While all birds are equally related to T. rex, chickens share some unique characteristics with this ancient dinosaur, such as two legs and scaly feet. This evolutionary link between chickens and T. rex has not only changed our perception of dinosaurs but has also deepened our understanding of the complex web of connections that make up the tree of life.

T. Rex is more closely related to birds than similar hulking predators
It is widely believed that chickens are the closest living relatives of the Tyrannosaurus rex. This claim is based on evidence from a fossil discovered in 2003 that allowed scientists to extract enough DNA for research. The 68-million-year-old fossil was compared to the DNA of 21 modern animal species, and the proteins found in the DNA of the T-Rex were most like those of the chicken.
However, this claim is misleading. While chickens are indeed related to T-Rex, so are penguins, ostriches, hawks, hummingbirds, parrots, and every other bird alive today. The distinction is important to understanding the processes of evolution. The T-Rex's lineage split from the birds about 160 million years ago, and then birds had another 66 million years of evolution until chickens emerged.
Before the discovery of the fossil, some scientists observed that chickens and T-Rex had similar characteristics. Both 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. These similarities led to the hypothesis that birds and dinosaurs shared a common ancestry, which was confirmed through molecular analysis.
The T-Rex is more closely related to birds than similar hulking predators. This is because both Tyrannosaurus and Paraves, the clade of dinosaurs that includes birds and Velociraptors, are theropods, meaning they 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. While hollow bones in T-Rex allowed for bulkier bodies, ancient birds used them to lighten their load and take flight.

The T. Rex fossil discovered in 2003 allowed scientists to extract DNA for research
The T. rex fossil discovered in 2003 by John Horner of the Museum of the Rockies in Montana and Wyoming allowed scientists to extract DNA for research. This discovery provided valuable insights into the evolutionary history of the T. rex and its relationship to modern-day birds.
The fossil, found in a barren fossil-rich area, included a fossil femur from which scraps of dinosaur protein were extracted. This protein, approximately 68 million years old, was analysed along with the protein of 21 modern species. The molecular analysis confirmed that T. rex shared a common ancestry with chickens, ostriches, and to a lesser extent, alligators.
This discovery supported the long-held hypothesis that birds are the closest living relatives of dinosaurs, an idea previously based on morphological similarities between bird and dinosaur skeletons. The research, published in the journal Science, was the first to use molecular data to place a non-avian dinosaur in a phylogenetic tree, mapping the evolution of species.
While the chicken is often touted as the closest living relative of the T. rex, this is a misleading simplification. The lineage that resulted in the T. rex split from the lineage of birds about 160 million years ago, and birds have had another 66 million years of evolution since the extinction of the T. rex. Therefore, all modern birds are equally related to the T. rex, and it is more accurate to say that every bird species is in a 12,000-way tie for closest living relative.
The T. rex fossil discovered in 2003, along with subsequent research, has provided valuable insights into the evolutionary history of this ancient creature and its relationship to modern-day birds.

The T. Rex's closest living relative is not just the chicken, but all birds
The Tyrannosaurus Rex, or T. Rex, is often thought of as a fearsome, giant predator. However, its closest living relative is often said to be the chicken. But this is only partly true, as all birds are equally the closest living relative of the T. Rex.
The idea that birds are living dinosaurs has been around for a while, with many anatomical similarities between the two groups. Both T. Rex and chickens, for example, walk on two legs, have scaly feet with sharp claws, and have long necks with big heads. Some dinosaurs even had feathers. However, it was believed for a long time that dinosaurs were slow, cold-blooded reptiles.
In 2003, a unique fossil of the T. Rex was discovered with soft tissue intact, allowing 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 similar to those of the chicken. This provided strong evidence that the chicken is the closest living relative of the T. Rex.
However, this conclusion is misleading. While chickens are indeed the closest living relative of the T. Rex, so are all other birds. The most recent common ancestor of the T. Rex and any bird is the exact same. So, while it is true that the T. Rex's closest living relative is the chicken, it is also true that every other bird species is equally closely related to the T. Rex. This includes birds like ostriches, hawks, hummingbirds, parrots, and penguins.
The distinction between saying that the chicken is the closest living relative of the T. Rex, and saying that all birds are, may seem like splitting hairs. However, this delineation is incredibly important for understanding the processes of evolution and the complex relationships between different groups of organisms.
