Top 10 in the world of hybrids



A hybrid is the love child of two different species. Some are born in nature, while others merge in a Petri dish. However, there is a special club in this strange world – hybrids seen for the first time.

When hybrids are created by scientists, novelty is not a factor. Hybrids can rescue critically endangered species and heal human diseases. In nature, it's all about strange mixtures. When exotic pets are released into the wild or rare animals can not find their own mates, the urge to pass on genes is often strong enough to overcome the species barrier.

10 The Wholpin

When explorers around the shelter were working on the Hawaiian island of Kauai, they noticed something strange. A dolphin-like creature was constantly emerging. Photographs suggested that the animal was a hybrid because it had physical characteristics of different species.

In 2018, a year after it was discovered, scientists shot it. The arrow was harmless and reaped a skin sample. The DNA analysis showed that the father of the creature was a rough tooth dolphin and his mother a whale with melon head.

This "Wholphin" was the first of its kind to be recorded and even given a scientific name: Steno bredanensis . Although this rare hybrid could prove sterile, her own birth was not uncommon. [1]

The melon whale is a dolphin. Technically, these offspring could, if they wanted, produce plenty of wholegrain burners with other types of dolphins. Of course, this does not happen, but the rarity of Melonhead Whale in Hawaii may have something to do with it.

9 Cotton Candy Grapes

People who like healthy snacks and carnivals can now enjoy a strange fruit – grapes that taste like cotton candy. Anyone who hates genetic engineering or artificial aromas can breathe easily. This grape variety is the result of natural breeding.

California horticulturalists chose two species to work with. The first was a type of Vitis vinifera one of the most common species in grocery stores. The other was a concorded grape. This variety is used in Welch's jellies, juices and jams.

Both varieties are seedless and can not multiply naturally. This forced the scientists to extract grape embryos, grow them in test tubes and then plant them in a vineyard. It took about 100,000 test tubes until the cotton candy-cotton candy birth was born. [2]

Filled with 12 percent more sugar than other grapes, the fruit was a hit when it became public in 2011. The high sugar content prevents an old produce disease from occurring – fruit that often tasteless at the time of purchase.

8 Hybrid Hope For Rhinos

In 2018, the last male rhino male to the north died. The last women, his daughter and granddaughter, are infertile. Thanks to frozen semen and the only rhinoceros species that is not classified as endangered (the southern white), there is hope for their virtually extinct northern cousins.

The two species differ, but from four sperm scientists were able to produce hybrid embryos Northern rhinos and two eggs of the southern females. This is the first step in a long battle for the revival of the species. Even if the four hybrids have been successfully controlled by surrogates, the calves are a fraction of what is needed to establish a herd.

Future plans include harvesting eggs from the last two northern white females. (They have eggs but can not carry embryos.) This allows researchers to make whole white rhinos. Another ambitious plan is to produce sperm and eggs from their skin cells, something that has already been done with mice. [3]

7 Hybrid Pythons of Florida

The Burmese python is the first choice for owners of exotic snakes in the United States. However, some people could not handle them and released the snakes into the wild. With a length of 7 meters and a weight of up to 91 kilograms, these pets soon got used to Florida. Their presence was known since 1980 and eventually thousands slept. In 2018, researchers analyzed tail samples from 426 southern python pythons and found that 13 were not pure. Although mostly Burmese, the dozen of these bakers also contained the DNA of another invasive species that was released as unwanted pets – the Indian python. [4]

They came from India, Pakistan, Sri Lanka and Nepal smaller but faster. Interestingly, the genetic signature suggested that the two species have not lately produced the first crosses. They merged long before the Florida pythons reached a large population.

The newly discovered hybrids may be stronger and more adaptable than their parent, which is a problem. Native animals, especially small mammals, are regularly caught by the giant reptiles.

6 The Galveston Dogs

Red wolves once roamed the southeastern United States. The human factor killed so many that the last 1980 were brought into breeding facilities. Only 17 were clean. From this group, the breed produced enough animals to start in North Carolina (about 40 animals) and 200 captive animals.

In 2019, a biologist took photos of wild dogs in Galveston, Texas. He came across them, but was convinced that they looked different from the local coyotes. He made a well-founded assumption that they were red wolf hybrids, along with photos and physical samples. The latter were procured from animals killed by cars.

Surprisingly, the biologist's guess was not only correct, but was able to save the rare predator. The Texas pack contained DNA designed exclusively for the Red Wolf and the "ghost alleles". These alleles did not correspond to any known canine genes, including those of the red wolf. [5]

This genetic material was probably lost during combat Breeding programs survived, however, in the Galveston dogs. Scientists hope to use the dogs to restore this genetic heritage to the wolf and to increase their numbers and health.

5 Chicken With Dinosaur Legs

The recent fossils prove that some dinosaurs have survived and evolved into modern birds. In 2016, scientists from Chile wanted to see how the leg bones of dinosaurs have changed over time. Like modern birds, they had two bones in the lower limb, the fibula and the tibia. Her fibula was a long tube that reached the ankle. The tibia was about the same length and positioned next to it.

Evolution brought the next group of Vogeldinos – the Pygostylians. By that time, the fibula had shortened and developed a sliver-like end. Modern bird embryos show signs of developing lengthy dinosaur fibulae, but they soon become shorter and grow to pygostylic ends.

To see this development in action, the scientists suppressed the IHH gene in chicken embryos. As a result, leg bones of equal length grew down to the ankle, which are very similar to the dinosaurs.

The Dino chickens did not hatch, but they revealed that IHH was actively preventing modern bones from returning to a dinosaur state. This was also the first time that researchers looked at the dinosaur-bird transition into living things previously seen only in the fossil record. [6]

4 Human-Sheep Hybrids [19659033] It may sound bizarre to create a human sheep, but the motivation behind this hybrid is life-saving. If researchers can take things to the next level, this combination could address the shortage of donor organs in the world. It could even cure type 1 diabetes.

In 2018, Stanford University created the first human and ovarian embryos. These embryos were allowed to mature in a replacement animal for some time before being slaughtered. Unfortunately, the law does not allow hybrids to survive the last 21 days. [7]

Although the project had to end there, this was the root-phase for the growth of unlimited human organs – especially the pancreas -. in the farm animals. Experiments had already cured a diabetic mouse with another mouse pancreas grown in a rat.

The researchers plan to grow modified sheep that lack the organ and hope that the animal's human DNA will be enhanced and a pancreas will emerge. However, to reach this stage, the experiment must last at least 70 days, which would require special regulatory approval.

3 Burkets Warbler

In Pennsylvania, two Warbler species (blue or golden-winged) often intersect. Depending on the color, their hybrids are known as either Brewster's or Lawrence's Warbler.

In 2018, an avid birdwatcher photographed what he considered a Brewster. However, when Lowell Burket later examined the images, his experienced eye noticed that the bird had no markings.

The two breast patches belonged to a completely different genus. On the suspicion that the bird was the offspring of a chestnut woodcutter and a blue-and-gold hybrid, Burket patiently waited for him to sing. Warbler species have distinctive songs, and when that strange bird opened its beak, it sang like a chestnut-side warbler.

The birdwatcher sent pictures, videos and his theory to ornithology experts. They were so convinced of his evidence that they helped Burket catch the bird. Blood tests confirmed that the mother of the warbler was a Brewster hybrid bred with a chestnut male. The ultra-pure three-species hybrid was named "Burket's Warbler" in honor of the man who found it. [8]

2 Extinct Turtle Lives

About 150 years ago, a giant turtle was declared extinct. The last one was seen on the island of Floreana, which belongs to the Galapagos Islands in the Pacific Ocean. Chelonoidis elephantopus had a saddle-shaped shell, while the shells of other turtle species were domed on the islands.

These giant tortoises were spectacular and had a length of up to 1.8 meters with a weight of 408 kilograms. Recently, researchers have noticed a change in another giant species.

Chelonoidis becki lives on Isabela Island, which is about 322 kilometers from Floreana. Some had saddle shells if they were to be arched. Samples were taken from 1669 turtles. Incredibly, 84 had enough genetic markers to suspect that one parent had died out C. Elephantopus . More encouraging were 30 of the hybrids under 15 years old. [9]

Their genetic diversity also suggests that at least 38 distinct C. elephantopus left on Isabela offspring. Because they can live to be 100 years old, some could even be alive. If so, this is the first rediscovery of a species thanks to the left behind hybrid offspring.

1 The hybrid that became a species

The Amazon is known for comical animals, but a bird surprised even the experts. In 1957, a new manakin was identified and named the golden-crowned variety. The little bird was clearly a species with its own population and its own territory. Nothing seemed unusual. Then he disappeared for 45 years until 2002.

In 2018, genetic tests showed that the rare birds were hybrids. They carried 20 percent of the Manakin genome with snow and 80 percent of the Opak Manakin. It sounds like another intersection, but this was the first hybrid bird found on the planet. [10]

It is worth noting that the parent genre produced the new one 180,000 years ago. By overcoming epic obstacles that almost all hybrids fail, the gold-crowned bird became a real species.

Apart from the fact that not all hybrids are new, the bird also looked different than his "parents". All three had green bodies, but others had head shadows. The snow-covered one had white feathers, while the opal crown shimmered in dazzling colors. The golden-crowned manakin developed a bright yellow cap.
