Advancements in medicine, all forms of communications, and even gene-editing to move away from naturally occurring genetic defects have leap-frog events recorded in months and years rather than generational. These advancements not only benefit the human race, but can also be applied toward our fellow creatures on the earth. Some of these new discoveries include the possibility of bringing back extinct animals. With the right set of tools, such an ambitious endeavor could be realized in the near future. But first, a little history.<\/p>\n<h3>The Carolina Parakeet<\/h3>\n<figure id=\"attachment_27523\" aria-describedby=\"caption-attachment-27523\" style=\"width: 300px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-27523\" src=\"https:\/\/lafeber.com\/pet-birds\/wp-content\/uploads\/2019\/12\/Conuropsis_carolinensis_Carolina_parakeet-300x278.jpg\" alt=\"Carolina Parakeet specimen posed on a perch\" width=\"300\" height=\"278\" srcset=\"https:\/\/lafeber.com\/pet-birds\/wp-content\/uploads\/2019\/12\/Conuropsis_carolinensis_Carolina_parakeet-300x278.jpg 300w, https:\/\/lafeber.com\/pet-birds\/wp-content\/uploads\/2019\/12\/Conuropsis_carolinensis_Carolina_parakeet-700x648.jpg 700w, https:\/\/lafeber.com\/pet-birds\/wp-content\/uploads\/2019\/12\/Conuropsis_carolinensis_Carolina_parakeet-768x710.jpg 768w, https:\/\/lafeber.com\/pet-birds\/wp-content\/uploads\/2019\/12\/Conuropsis_carolinensis_Carolina_parakeet.jpg 1200w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-27523\" class=\"wp-caption-text\">The last verified Carolina parakeet died in February 1918 in the Cincinnati Zoo.

At one time, the United States was home to its own parrot species \u2014 one of two \u2014 that thrived within its borders. That bird was known as the Carolina parakeet. This bird was found as far north as New York, as far south as Florida, and as far west as Colorado. These beautiful birds eventually died out in captivity in 1918. For over a hundred years, America has been deprived of its own exotic bird species.<\/p>\n<p>The Carolina parakeet was a small bird with a green body, a yellow head, and a red\/orange face. For millions of years, these birds flocked throughout their adopted regions. As people began to colonize these regions, their interference in the habitats required for the Carolina parakeet began to contribute to the birds\u2019 decline in population. Eventually, and for a variety of reasons, the bird was soon extinct, never to grace the skies of America again.<\/p>\n<h3>The Sun Conure Connection<\/h3>\n<figure id=\"attachment_43707\" aria-describedby=\"caption-attachment-43707\" style=\"width: 300px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-43707\" src=\"https:\/\/lafeber.com\/pet-birds\/wp-content\/uploads\/2019\/12\/sun-conure-px-5951906-300x300.jpg\" alt=\"sun conure perched on branch leaning to the side\" width=\"300\" height=\"300\" srcset=\"https:\/\/lafeber.com\/pet-birds\/wp-content\/uploads\/2019\/12\/sun-conure-px-5951906-300x300.jpg 300w, https:\/\/lafeber.com\/pet-birds\/wp-content\/uploads\/2019\/12\/sun-conure-px-5951906-100x100.jpg 100w, https:\/\/lafeber.com\/pet-birds\/wp-content\/uploads\/2019\/12\/sun-conure-px-5951906-768x768.jpg 768w, https:\/\/lafeber.com\/pet-birds\/wp-content\/uploads\/2019\/12\/sun-conure-px-5951906.jpg 800w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-43707\" class=\"wp-caption-text\">Photo by <a href=\"https:\/\/pixabay.com\/photos\/parrot-bird-feathers-plumage-5951906\/\" target=\"_blank\" rel=\"noopener\">rutpratheep0\/Pixabay<\/a><\/figcaption><\/figure>\n<p>Recently, scientists involved in gene-mapping visited the closest living relative of the Carolina parakeet, the sun parakeet. The sun parakeet is found in the South American tropical regions. They are themselves considered a threatened species. More sun parakeets live in homes rather than the wild. Also known as the <a href=\"https:\/\/lafeber.com\/pet-birds\/species\/sun-conure\/\">sun conure<\/a>, this bird is the one that has yielded up its genome as a guide for the evolutionary biologists in mapping the genome of the extinct Carolina parakeet. With DNA extracted from a stuffed bird, the scientists completed their studies to learn how the US-based parakeet actually declined and died off.<\/p>\n<p>Their <a href=\"https:\/\/www.cell.com\/current-biology\/fulltext\/S0960-9822(19)31438-1\" target=\"_blank\" rel=\"noopener noreferrer\">studies showed<\/a> that expected warning indicators in the constantly developing DNA of these birds did not create a pointing finger to the suspected cause. Instead, it only proved that the decimation was probably our fault. However, a good thing that came from this mapping is what it could mean for other bird populations that are declining. Biologists could test DNA of living birds in an attempt to detect possible warning signs of the reason for their declines. This could go a long way in trying to help the bird adapt, and thus prevent more extinction events.<\/p>\n<p>In time, DNA extraction and genome mapping could become a boon. For now, such technology is a tool for better discoveries as we move toward a better tomorrow. Interestingly, the Carolina parakeet had an appetite for cockleburs. The common cocklebur is a plant that is toxic to animals \u2014 except for the Carolina parakeet, once upon a time. The consumption of the plant left the bird a toxic meal for predators. And yet, the native parakeet was immune. This same study provided the answer to the bird\u2019s safe eating of the plant \u2014 two proteins that interacted with the poison to make the deadly plant safe.<\/p>\n<p>Eventually, science might be able to create extraordinary avenues of protection from extinction, as well as the possible return of some desired creatures. Time will tell.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Carolina parakeet was native to North America but, sadly, became extinct a century ago.
