What are the creatures that are now extinct due to humans?

That’s a lot! This is just part of it! ?The most famous is the dodo bird!

On average, one species becomes extinct every hour. Scientists believe that the earth is experiencing the "sixth mass extinction of life"

In the history of the evolution of life on earth, there have been five large-scale biological extinctions Extinction. The first mass extinction occurred at the end of the Ordovician period 440 million years ago, with approximately 85% of species extinct; the second mass extinction occurred during the Devonian period approximately 365 million years ago. In the later period, marine life was severely damaged; the third mass extinction, which occurred at the end of the Permian about 250 million years ago, was the largest and most serious in history. 96% of species were extinct, including 90% of the ocean. Living things and 70% of terrestrial vertebrates became extinct; the fourth occurred 185 million years ago, and 80% of reptiles became extinct; the fifth occurred in the Cretaceous period 65 million years ago, ruling the earth for 160 million years The extinction of the dinosaurs.

Scientists believe that the first five mass extinctions were natural disasters, and the sixth mass extinction event was "directed" by humans. Biological extinction events in history are very similar, even faster. According to surveys, one species becomes extinct on average every hour on the earth, and the extinction rate exceeds anything in the past.

1. Quagga. (Extinct since 1883).

Also known as the quagga, a subspecies of the common zebra. In 1788, the quagga was first recognized as an independent species. It was classified and called the equine quagga. The quagga was hunted unscrupulously for its meat and skin, leading to extinction. The last living specimen of the quagga that was kept in captivity died in August 1883. At the Artis Magistra Zoo in Amsterdam, the Netherlands.

The quagga is actually a subspecies of the prairie zebra. The back half of its body is black, but its belly and limbs are white. The quagga has a long neck and a long head, but its ears are very short. In 1883, the quagga disappeared from the earth forever.

2. Cattle (extinct since 1768). Unprepared livestock, capable of growing up to 25.9 feet (equivalent to 7.9 meters), and adults typically weighing 3 tons. Large numbers of Stella sea cows once roamed the North Pacific coast. The activities in southern Japan and California are likely to be caused by the arrival of humans, which not only led to the extinction of Stella sea cows in this area, but also caused the extinction of Stella sea cows in other areas.

The Stella sea cow is also called Stella sea cow. Stella's sea cow, a toothless manatee, mainly lives in the Comandore Islands. Stella's sea cow is huge, with a body length of 7 to 8 meters and a weight of 3 to 4 tons. It is the second largest mammal in the ocean. Animals.

3. Thylacine (extinct in 1936), a famous carnivore with a bag on its body, native to Australia and New Guinea, commonly known as the Tasmanian tiger. . The origin of this species dates back to the early Miocene of the Tertiary Period. Although this species has been considered extinct, there are still many reports of Thylacine sightings

Thylacine, in English. Named Thylacine Tasmanian wolf, it was once widely distributed on the Australian mainland and nearby islands (extinct in 1936). After European immigrants settled in Australia, the thylacine became extinct on the Australian mainland and is still distributed only on the island of Tasmania in southern Australia. Some believe wild populations are extinct. The body is like a dog and the head is like a wolf. The shoulder height is 600 mm, the body length is 750 mm, and the tail length is 530 mm. The coat color is earthy gray or yellowish brown, with 14-18 black stripes on the back. The hair is short, dense and very hard. The cleft in the mouth is very long. There are 5 toes on the front feet and 4 on the hind feet.

4.?Irish giant deer (extinct about 7700 years ago). Also known as the Giant Deer, it was the largest deer that ever lived on Earth. They live across Eurasia - from Ireland to Lake Baikal - and date back to 5700 BC. The giant deer is about 7 feet tall at the shoulder, has the largest antlers of any cervid, and can weigh up to 90 pounds

The Irish giant deer, also known as the giant deer, was the largest deer that ever lived on earth. Now extinct

5. Caspian tiger (extinct in 1970). The world's third largest tiger, also known as the Persian tiger, is the westernmost subspecies of tiger.

The Caspian tiger's cheeks are covered with short hairs. The male Caspian tiger is huge, weighing about 169 kg - 240 kg. Female Caspian tigers are not as big as male Caspian tigers, weighing only 85kg-135kg. There are still reports of sightings of Caspian tigers.

The Caspian tiger is a large carnivore with a long and strong body. Males and females generally hunt and feed alone. Active at night, but also active during the day. Generally feed on large hoofed mammals, such as deer, cows, etc. Caspian tigers usually reach sexual maturity at the age of 3 to 4 years. A female tiger usually gives birth to 3 to 4 cubs at a time, and usually no more than two survive. The dead and emaciated tiger cubs will be eaten by the female tiger.

6. European bison (extinct in 1627). One of the most famous extinct animals in Europe, it has a very large size and was introduced to Europe 250,000 years ago. Hunting giant animals anywhere was the prerogative of the nobility, and later slowly became only the prerogative of the royal family. The last remaining European female bison died in the Jaktorów? Forest Park in Poland in 1627

The European bison is one of the most famous extinct animals in Europe. The European aurochs and ancient European aurochs (supposedly the ancestors of modern domestic cattle) were extremely large. Two million years ago, European bison were introduced to India. It was then introduced to the Middle East, then Asia, and finally Europe 250,000 years ago. This animal was first described in scientific literature by Linnaeus in 1758. In the 20th century, European scientists used cattle that had been domesticated to breed new European bison (Heck bison). Compared with the biological characteristics of wild European bison, they are not completely similar.

7. Auk (extinct since 1844). The great auk is the only flightless species among the auks and is huge in size. Coming from the Atlantic Ocean, it has survived into modern times, but unfortunately, the great auk is no longer seen today. It is also called a petrel or a penguin. It stands approximately 30-34 feet tall (75 cm) and weighs 5 kg. The flightless auk is the largest species of auk. Wrecks found in middens in Florida indicate that they flew south sporadically during the winter as late as the fourteenth century.

The great auk is a small flying water bird. They once lived widely on various islands in the Atlantic Ocean. The great auk is very similar to a penguin in shape and appearance. It has a thick body, a white belly, and a head to The back is black. Because its wings have degraded, it can only glide low in its sleep. When it dives into the water, it will continue to flap its wings and act as a powerful propulsion. Except for the breeding season, auks rarely live on land. They like collective activities, often gathering in hundreds or thousands, floating on the sea or diving into the sea to prey on small fish and shrimps. The auks’ nests are very simple. Each "couple" just picked up a few sticks of hay on the island, put them on the rock shelter, and then got there. The auk's reproductive capacity is extremely low, and it only lays one egg at a time. Each egg has a variety of colors and markings, and looks very delicate.

8. The cave lion, also known as the European cave lion or the Eurasian cave lion, is the ancestor of the lion and an extinct subspecies of the lion. This subspecies is the largest of the lion species. ?It lives in caves and is a carnivore, preying on ground otters, small rodents, and other herbivores. Cave lions became extinct during the Pleistocene (about 3 million to 10,000 years ago).

9. Dodo (extinct since the end of the 17th century). The dodo is a flightless bird that lives on the island of Mauritius. It stood three feet tall (1 meter), fed on fruit and lived on land. The dodo has been extinct since the mid-to-late seventeenth century, which can be attributed to human activity.

Dodo, scientific name: Raphuscucullatus. Birds in the order Columbiformes (sometimes painted as Raphiformes) in the family Raphidae. They are native to Mauritius and became extinct in 1681. The dodo cannot fly. This family contains 3 species, others Two species are R. solitarius (extinct in 1746) of Reunion Island and Pezophaps solitaria (Pezophapssolitaria) of Rodrigues (extinct in about 1790). ). The dodo is larger than the rooster and weighs about 23 kilograms (about 50 pounds). It has blue-gray body feathers and a large head. It has a light black bill with a light red sheath forming a hook tip.

The wings are too small to fly. The feet are strong and yellow, with a bunch of curved feathers high on the back end of the feet. The Reunion solitary pigeon may be an albino variant of the dodo. The Rodriguez solitary pigeon is light brown, with a taller and slender body, a smaller head, a short beak without a thick hook tip, and ridges on its wings. A dodo's head and feet are now preserved at Oxford University, only one foot is preserved in the British Museum, and a head is preserved in Copenhagen. Several museums in Europe, the United States and Mauritius preserve a number of complete skeletons. Many skeletons of the solitary pigeon have also been preserved.
