The idea of building a dinosaur from a chicken may seem like something out of a science fiction novel, but it is an idea that has been explored by scientists and paleontologists. The concept is based on the fact that chickens are the closest living relatives of some famous dinosaurs, such as the Velociraptor and Tyrannosaurus Rex, and thus share a common ancestry with dinosaurs. While the idea of extracting and re-implanting dinosaur DNA, as depicted in the Jurassic Park franchise, is not feasible due to DNA degradation, scientists have explored the possibility of genetically engineering chickens to exhibit dinosaur-like traits, such as teeth, tails, and hands. This process, known as atavism activation, involves manipulating specific genes in chicken embryos to reactivate ancestral traits. While progress has been made in creating chicken embryos with dinosaur-like features, the ethical implications and limitations of such experiments have sparked debates among scientists and the public alike.

What You'll Learn
The chicken is a dinosaur
Chickens, as we know them today, are the result of millions of years of evolution and adaptation. They are descendants of the dinosaurs, specifically theropod dinosaurs, which also include the Tyrannosaurus rex (T. rex). This relationship was discovered through scientific research and DNA comparisons. In 2003, a remarkable fossil of the T. rex was found with soft tissue intact, allowing scientists to extract and study its DNA. By comparing the DNA sequences of the T. rex and various modern species, it was determined that the proteins in the T. rex DNA were most similar to those of the chicken.
Furthermore, chickens share anatomical similarities with dinosaurs, particularly in their bone structure. Additionally, it is believed that many dinosaurs had feathers, which were adapted for heat regulation and courtship displays, rather than for flight. This provides further evidence of the evolutionary link between chickens and dinosaurs.
Renowned paleontologist Jack Horner has dedicated his career to reconstructing dinosaurs. While he has discovered fossils with well-preserved blood vessels and soft tissues, intact dinosaur DNA has remained elusive. As a result, Horner has turned to a novel approach: using chickens, the living descendants of dinosaurs, and genetically engineering them to reactivate ancestral traits. His goal is to create a "Chickenosaurus" by reintroducing dinosaur-like characteristics such as teeth, tails, and even hands.
In conclusion, when we state that "the chicken is a dinosaur," we are acknowledging the evolutionary relationship between these seemingly disparate creatures. Chickens are not just descendants of dinosaurs but are classified as modern-day dinosaurs themselves. This understanding highlights the fascinating journey of evolution and the ongoing quest to unravel the mysteries of our prehistoric past.

Jack Horner's approach
Jack Horner is a world-renowned paleontologist known for his fieldwork and research on dinosaur growth and behaviours. He has made several important discoveries, including the first dinosaur eggs and embryos in the Western Hemisphere and the first evidence of dinosaurs nesting in colonies and caring for their young. Horner has spent his career trying to reconstruct dinosaurs and has found fossils with well-preserved blood vessels and soft tissues but never intact DNA.
Horner's approach to building a dinosaur from a chicken involves taking living descendants of dinosaurs (chickens) and genetically engineering them to reactivate ancestral traits. This process is known as reverse evolutionary engineering. The goal is to create a "Chickenosaurus" by reintroducing dinosaur-like features such as teeth, tails, and even hands.
Horner's lab has been studying the biology of bird tails to understand the evolutionary changes that occurred so that they can be reversed. They have discovered that introducing the Lin28 protein at the end of chicken embryo tails can extend tail length. The next step is to use CRISPR technology to modify the chicken's DNA and ensure that the long-tailed trait is passed on to future generations of chickens.
Additionally, Horner's team has found that certain modern birds already possess traits such as wing claws and elaborate head crests, which are similar to those found in dinosaurs. By appropriating these existing traits and combining them with the re-engineered features, they aim to create a creature that resembles a dinosaur.
Horner's work has excited many people who dream of encountering dinosaurs, and his research has also led to unexpected discoveries in other areas, such as a potential trigger for the human back disease Ankylosing Spondylitis.

Atavism activation
Chickens, or avian dinosaurs, have many dormant dinosaur traits in their genetic code that are switched off during the embryonic stage of development. Scientists have discovered methods to turn off the genes that suppress these traits, allowing chicken embryos to retain skeletal characteristics similar to their dinosaur ancestors, such as tails and dinosaur-like legs.
To create a dinosaur from a chicken, the goal is to reactivate specific ancestral traits to make a "'Chickenosaurus." This includes the reactivation of teeth, tails, and even hands. Renowned paleontologist Jack Horner has pioneered this approach, taking living descendants of dinosaurs, like chickens, and genetically engineering them to reactivate these ancestral traits.
Dr. Hans Larsson of McGill University is also studying atavisms by examining the embryonic development of birds and the loss of certain traits, such as tails and the transformation of hands into wings. By understanding the genetic basis of these losses, the idea is to reverse the process and reactivate the ancestral traits to create a more dinosaur-like creature.
While the concept of atavism activation may seem like a fascinating scientific endeavor or a way to satisfy curiosity about dinosaurs, it also raises ethical concerns and questions about the potential consequences of tampering with nature.

Genetically engineering a Chickenosaurus
The idea of genetically engineering a "Chickenosaurus" is not purely science fiction. It is based on the fact that chickens share a common ancestry with dinosaurs. This link was first proposed in 1869 by English biologist Thomas Huxley, a friend of Darwin, who discovered avian traits in the skull of a Megalosaurus.
Since chickens are the closest living relatives of some famous dinosaurs, such as the Velociraptor and Tyrannosaurus Rex, it is theoretically possible to reactivate ancestral traits in chickens to make them more dinosaur-like. This process is known as atavism activation or reverse evolutionary engineering. Scientists have already managed to turn on certain ancestral characteristics in chickens, such as teeth. In 2006, researchers from the University of Wisconsin discovered a link between a specific chicken gene and tooth growth. They found that chicken embryos with a mutation on this gene developed sharp teeth.
In 2015, a team of Yale researchers identified a set of genes known as "non-avian reptilian facial patterning genes," which are believed to have played a key role in the development of dinosaur facial features. By manipulating these genes in chicken embryos, researchers were able to create embryos with snouts and palates that more closely resembled those of their dinosaur ancestors.
In 2016, a team from the University of Chile created chicken embryos with "dinosaur legs" by inhibiting the expression of the Indian Hedgehog (IHH) gene, which controls fibula development in chickens. This resulted in the growth of longer, more dinosaur-like fibulas. While these genetic manipulations have shown that it is possible to create more dinosaur-like characteristics in chickens, there are still many challenges to creating a fully-fledged "Chickenosaurus." For example, the tail is supposed to be one of the hardest parts to recreate, and there may be ethical concerns about the potential impact on the diet and survival of these genetically modified organisms. Some even argue that it is a waste of time and money.

The ethics of bringing back dinosaurs
One of the primary ethical dilemmas surrounding the revival of dinosaurs pertains to the potential impact on the environment and ecosystem. Dinosaurs went extinct millions of years ago, and the current ecological balance is vastly different from what it was during their existence. Introducing dinosaurs into modern ecosystems could have unpredictable and potentially detrimental effects on the environment and other species. Altering ecosystems through the introduction of extinct species could disrupt food chains, impact biodiversity, and lead to unforeseen consequences.
Another ethical concern arises from the potential treatment and exploitation of dinosaurs. If dinosaurs were to be brought back, they might be confined to zoos, amusement parks, or research facilities, raising ethical questions about their captivity and welfare. The potential commodification and exploitation of dinosaurs for entertainment or commercial purposes could be highly controversial and pose significant ethical challenges.
Additionally, the process of de-extinction itself presents ethical dilemmas. The methods used to bring back dinosaurs, such as genetic engineering or cloning, involve manipulating DNA and altering the traits of existing species. This raises ethical questions about the potential risks and unintended consequences of such interventions. The potential impact on the species used as a basis for de-extinction, as well as the possibility of unforeseen genetic abnormalities or health issues in the resurrected dinosaurs, are important considerations.
Furthermore, the resources and priorities involved in de-extinction efforts are ethically significant. De-extinction research and the potential revival of extinct species require significant scientific resources and funding. Ethical questions arise regarding the allocation of resources, especially when there are pressing global issues, such as conservation efforts for endangered species currently facing extinction or addressing the impacts of climate change.
Lastly, the ethical implications of bringing back dinosaurs extend to our understanding of our role and responsibility in shaping the natural world. The ability to resurrect extinct species challenges our relationship with nature and raises philosophical questions about the boundaries of human intervention. It prompts discussions about the potential consequences of altering the course of evolution and the ethical responsibilities that come with such powerful capabilities.
