This list of extinct animals is a list that will never grow shorter, and it is a list of all the animals that we have lost forever.
There are many reasons why these animals became extinct – some because they were hunted by humans and others who couldn’t adapt to change in their environment. This list serves as a reminder for us to stop hunting so many species today before it’s too late!
The list of extinct animals includes the Tasmanian tiger, the dodo bird, and many more.
The Extinct Animals List
The Dodo is known as one of the most famous extinct animals in history! It lived on an island called Mauritius and had no natural predators until humans arrived there in 1598 when they were immediately killed for sport or food. These flightless birds became extinct within just 100 years after this happened – likely because they couldn’t compete against other species that invaded their environment once it was gone.
The Quagga is another example of an animal that has gone extinct because of human activity. The Quagga was closely related to the plains zebra but had stripes on its rear instead of its whole body. The extinction of the Quagga can be traced back to hunting for its valuable pelts and habitat loss.
The Pyrenean ibex, also known as the bucardo, was a species of wild goat that inhabited the Pyrenees. Occupying the mountain range bordering France and Spain, it became extinct in 2000 due to a fungal infection spread from deer herds crossing into its territory. The last known representative of the species was a female named Celia.
She died on January 6th, 2000, after being shot by a hunter. However, cell tissue from skin samples taken from a dead animal was used to create embryos implanted into domestic goats. As such, genetic samples can still be found today.
The Tasmanian tiger was a marsupial native to Tasmania. Its extinction in 1936 was due to both human hunting and being prey for farm animals.
This method involves the implantation of an embryo into a surrogate’s uterus, encouraging growth into a fetus. Since the Tasmanian tiger is extinct, it requires access to tissues from old specimens to create embryos using somatic cell nuclear transfer. Again, museums are likely candidates for this type of research.
The thylacine, also known as the Tassie tiger or Tasmanian wolf, was a carnivorous marsupial that once inhabited mainland Australia and New Guinea.
This extinction is attributed to human hunting and competition from other animals over food resources. To revive the thylacine from death, scientists would be able to conduct somatic cell nuclear transfer on specimens that have been preserved in museums around the world. Again, this process requires tissue samples from dead specimens to create embryos that can be implanted into surrogate mothers’ uteruses for development into fetuses.
Before humans began to use them for labor and food, the passenger pigeon had a wide range throughout North America. Their population was estimated to be around three billion in total. However, they went extinct due to hunting and deforestation. To revive this previously abundant species for future generations, scientists would need access to cells from dead specimens of the passenger pigeon.
The most likely candidate for this is checking museums and other facilities where taxidermied birds are kept. By taking tissue samples and placing them into living germline cells (cells that give rise to gametes), they can artificially induce the creation of an embryo with a genome which will lead to a clone being born.
Aurochs are considered to be ancestors of modern cattle. They once had a wide range throughout Eurasia but went extinct in 1627 due to excessive hunting. However, DNA extracted from specimens preserved in museums may still be usable by researchers looking into reviving this animal through genetic engineering.
This method would take tissue samples from old specimens and insert them into egg cells, giving rise to cloned embryos containing the specific genome needed. These embryos could then be implanted into surrogate mothers’ uteruses and brought to term.
How Science can Bring Back These Extinct Animals
To compensate for human-driven extinction and maintain population diversity, the IJE has created The Frozen Ark project. Its goal is to genetically recreate recently extinct large mammals such as the Quagga, the Tasmanian tiger, and of course, the Pyrenean ibex. Since their extinction in 2010, these animals have become topical interests for new research proposals.
The IJE has already made progress using de-extinction methods on lab mice by implanting them into surrogate mothers.
Two mice survived past birth for about fifty days before dying due to lung defects. While this is undoubtedly a minor breakthrough that could lead to discoveries in genetic engineering, it is still unclear if de-extinction can be successfully implemented for larger mammals.
In the case of the Pyrenean Ibex, scientists have identified a solution that would allow them to implant DNA into a cloned animal.
This method is called somatic cell nuclear transfer. In this process, scientists would take skin samples from deceased animals and subject them to aging while storing cells in a dormant state.
Once they have acquired enough cells from one source, they can inject it into an enucleated egg cell and induce development by introducing a surrogate mother’s cytoplasmic factors. The result is an embryo with identical DNA to that of the donor (the Pyrenean ibex).
Today, these are some examples of how quickly species can go from existing all over Earth to becoming completely extinct forever if we don’t stop hunting them down before too many disappear! While extinction doesn’t happen overnight, it can happen if we don’t stop killing these animals.
De-extinction may have several benefits for humanity and the environment; it also comes with many ethical and financial concerns. For one, there is debate about where all of these revived species will be housed and whether or not zoos are appropriate environments for their survival. Another concern is the cost of restoring extinct species. It took between 4 million and 7 million US dollars to clone a single cow in 2008.
