10 Animals That Hunted Our Ancestors

10 Animals That Hunted Our Ancestors

People are usually not actually thought-about apex predators as a result of there are a number of animals that may and typically will prey on us. However even the wildest of those animals don’t simply go round searching us, and most choose to maintain their distance. Nevertheless, this was not all the time the state of affairs.

For a lot of our evolutionary historical past, we have been on the menus of fairly a number of predators. Early people, hominins, historic primates, all ancestors of we Homo sapiens, bore the brunt of the vicious appetites of a number of wild animals that repeatedly hunted them for meals.

10 Saber-Toothed Cat

Saber-toothed cats didn’t hesitate to munch down on early people every time they acquired the chance.

In 2015, scientists recovered 300,000-year-old tooth and bone fossils from two saber-toothed cats in Schoningen, Germany. Checks revealed that a member of Homo heidelbergensis, a possible ancestor to the fashionable human, used one of many bones as a hammer.

Homo heidelbergensis was an excellent hunter. They used picket spears and have been able to taking down giant prey, together with rhinos, bison, and big deer. Nevertheless, they correctly steered away from the saber-toothed cat and solely killed it in self-defense.

One other discovery from the Djurab Desert in Chad revealed that Sahelanthropus tchadensis, a a lot older potential ancestor of people and chimpanzees that lived between 6.5 and seven.5 million years in the past, lived in shut proximity to at the very least three species of saber-toothed cats, together with the large Machairodus kabir.

M. kabir weighed between 350 and 490 kilograms (770–1,018 lb). For comparability, the most important tigers round as we speak weigh as much as 300 kilograms (660 lb). The fossil of the S. tchadensis was discovered amongst these of a number of animals, together with crocodiles, monkeys, horses, hyenas, and honey badgers. Historians consider the saber-toothed cat hunted S. tchadensis because it did the opposite animals.[1]

9 Haast’s Eagle

Maori folklore mentions the existence of an enormous hen that hunted and ate human infants centuries in the past. The Maori referred to as the fowl Te Hokioi (or Pouakai), however scientists consider it was the Haast’s eagle.

Simply because the Maori stated of Te Hokioi, the Haast’s eagle was able to catching human youngsters, and it most likely did. It wouldn’t have had a lot hassle killing an grownup human, both. In reality, the eagle’s main prey was the moa, an enormous, extinct flightless hen that was many occasions its measurement (and larger than a human).

The Haast’s eagle was the highest predator in New Zealand. It was zero.9 meters (Three ft) tall, 1.5 meters (5 ft) lengthy, and weighed 14 kilograms (31 lb). It had a wingspan of three meters (9.eight ft), and its beak and talons have been twice the dimensions of these of the most important eagle round at the moment.

The Maori not directly brought on the extinction of the Haast’s eagle once they hunted the moa to extinction. The Haast’s eagle went extinct round 1400, since there was no prey large enough to quench its vicious starvation.[2]

eight Crocodylus Anthropophagus

Crocodylus anthropophagus is a big extinct crocodile that hunted early people and hominins 1.84 million years in the past. Its choice for human flesh is even evident in its identify, anthropophagus, which primarily means “eater of humans.”

Scientists found the primary fossil of C. anthropophagus in Tananzia’s Olduvai Gorge in 2007. Homo habilis and Australopithecus boisei, two small progenitors of recent people, lived within the gorge on the time the crocodile lived there. Actually, scientists discovered a number of fossils with crocodile bites.

Historians consider the crocodile hid underwater and jumped out to catch prey that got here for a drink. Scientists consider the crocodile thought-about early people and hominins a serious meals supply.[3]

7 Snakes

People have an innate worry of snakes—a worry that decided how we advanced. Snakes and primates have been dwelling collectively for 100 million years. Snakes preyed on primates and thought of them simply one other supply of meals.

In response to Lynne Isbell of the College of California, the mortal worry of ending up in a snake’s stomach brought on historic primates to develop greater brains and sharper eyes. They might already see different predators from farther distances, however snakes have been harder to identify as a result of they slithered on the ground. They might stealthily transfer near their prey earlier than curling round them to suffocate them to demise.

Early primates advanced to see colour, motion, and in Three-D, which allowed them spot snakes. Round 60 million years in the past, the primary venomous snakes advanced; their venom was a way to defeat the improved eyesight of early primates. In return, early primates developed greater brains to course of visible info quicker. Snakes and people stay mortal enemies at present, though we’ll all agree people now have the higher hand.[4]

6 Crocodylus Thorbjarnarsoni

Crocodylus thorbjarnarsoni was one other historic crocodile that in all probability hunted early people. It lived in Lake Turkana in Kenya between two and 4 million years in the past. In crocodile trend, it hid underwater, stalking each animal that got here for a drink.

C. thorbjarnarsoni reached an enormous eight.Three meters (27.2 ft) lengthy, making it the most important crocodile ever. For comparability, the most important crocodile we now have in captivity is 6.1 meters (20.Three ft) lengthy. Early people additionally had a serious drawback towards C. thorbjarnarsoni : Measurement.

Early people have been a lot smaller on the time. They grew to only 1.2 meters (four ft) tall. This implies the crocodile might swallow them entire. Historians can’t affirm for positive if the crocodile ever ate early people, although, and it’s most unlikely they ever will. Any prey would have utterly digested within the crocodile’s abdomen.[5]

5 Cave Bear

The cave bear (Ursus spelaeus) first appeared round 100,000 years in the past and went extinct round 25,000 years in the past. It was native to Europe, the place it hibernated in caves in winter. A number of caves are suffering from the stays of the bear immediately. The individuals of the Center Ages even mistook its fossils for dragons.

The cave bear lived alongside Neanderthals till the arrival of recent people 40,000 years in the past. Each species of human shared the identical caves with the bears, resulting in violent confrontations. The confrontations have been solely over habitat, because the cave bear principally ate crops. People didn’t actively hunt the bear as a result of it was large and harmful. Nevertheless, they hunted it when vital.

Typically, the bears left their caves for different ones. Different occasions, the people lived within the caves in the summertime and left when the bears returned to hibernate in winter. Nevertheless, confrontations have been unavoidable, since unaware people might have strolled into an occupied cave, scary the bear.[6]

four Unidentified Eagle

In 1924, scientists unearthed a two-million-year-old fossil cranium of a younger Australopithecus africanus in South Africa. Scientists consider the hominin is the lacking hyperlink within the evolution of man, and its discovery is the rationale historians say people originated in Africa.

The fossil known as the Taung youngster and is believed to have been three and a half years previous on the time of dying. It was found with the fossils of a number of different animals, indicating they have been killed by a predator. Researchers initially suspected the Taung baby was killed by a saber-toothed cat or a leopard, however extra cautious remark of the marks on the cranium level towards an unidentified eagle.

The accidents on the cranium resemble one thing that may have been the handiwork of an eagle’s talon. It additionally has chew marks indicative of an eagle’s beak. The eagle would have been a ferocious predator with options just like the fashionable African topped eagle.

The marks on the finish of the Taung youngster’s eye socket are just like marks discovered on the stays of monkeys eaten by eagles. Eagles will often use their talons and beaks to take away the eyes to succeed in the mind. Bigger predators just like the leopard and the saber-toothed cat would have simply damaged the cranium as a result of the sockets would have been too small.

Nevertheless, some scientists insist that the Taung baby was eaten by a bigger predator since people would have been too massive to be hunted by an eagle. However the Taung youngster was a toddler on the time of demise, making it the identical measurement and even smaller than the common prey of the eagle. In reality, smaller trendy eagles are recognized to have killed human infants.[7]

Three Historic Hyenas

In 1994, scientists discovered a 500,000-year-old femur of a Homo rhodesiensis in a collapse Casablanca, Morocco. Homo rhodesiensis is a subspeices of Homo heidelbergensis, believed to be the widespread ancestor of Neanderthals and Homo sapiens. It wasn’t till the 21st century that scientists realized that they had the fossil of an early human as a result of the bone had been closely damaged and chewed by an extinct hyena.

Scientists know people and historic hyenas lived within the cave, though they might not affirm if each lived there on the similar time. Whereas they think the traditional human was hunted by hyenas, they aren’t leaping into conclusions. The Homo rhodesiensis might have died of different causes, and its stays have been eaten by hyenas.

Homo rhodesiensis was additionally a superb hunter who killed giant recreation. They might have even hunted the hyenas. Nevertheless, the hyenas have been additionally able to searching them. No matter occurred 500,000 years in the past, the invention is fascinating as a result of researchers not often discover the stays of human fossils eaten by predators.[8]

2 Different People

Scientists have uncovered a number of fossils of cannibalized Neanderthals in Europe. Nevertheless, they don’t assume Neanderthals often actively hunted their very own type for meals. The energy in a human are inadequate to maintain one other. A horse accommodates 200,000 energy, whereas a human accommodates a relatively measly 32,000.

However, Neanderthals might have contained extra energy because of larger muscle mass. In addition to, a number of fossils have been discovered collectively, indicating that the Neanderthals had eaten numerous different Neanderthals at a go. Scientists suspect Neanderthals killed their very own due to a famine, for rituals, or in self-defense.[9]

1 Virtually Each Carnivore

Proconsul, one in every of our earliest ancestors, was meals to principally something that ate meat. The genus lived in Africa roughly 20 million years in the past and is believed to be the primary true ape. It’s thought-about the widespread ancestor of apes and monkeys. It was between zero.9 and 1.5 meters (Three–5 ft) lengthy, weighed between 11 and 45 kilograms (25–100 lb), and didn’t have a tail.

Proconsul seemed like a monkey (apart from the shortage of a tail), had the intelligence of a monkey, and walked on all fours like a monkey. It was prey to principally all carnivores—from birds to mammals. Scientists have even discovered a number of 16- to 20-million-year-old fossils that have been eaten by creodonts, an extinct group of mammalian carnivores that thought-about Proconsul prey.[10]
