As Africa is the closest continent to the Equator, most of its animal species survived without changes, including the famous lions, elephants, giraffes, and gorillas. Marsupial species in Australia, like the kangaroo and the koala, survived through the Ice Age, although they too grew smaller.[Climate change] is the main factor driving the extinction,” Wang said. Therefore, when the last patches of vegetation in the Arctic tundra disappeared because of warmer climates, the mammoths that relied on it for food also vanished.The three main characters we all know from the movie Ice Age and its sequels are all based on animals that lived during the glacial age that began during the Pleistocene epoch. However, the identity of the acorn-obsessed saber-toothed squirrel named Scrat turned out to be a scientific surprise.
Why were Ice Age animals so big : Light Bones and Air Sacs
Finally, other evidence points to why prehistoric animals grew so massive, including those that took to the air. Studies indicate it could be because of their bones and lungs. Pterosaurs, for instance, conquered the skies long before the first dinosaurs.
What ended ice age
The overall trigger for the end of the last ice age came as Earth's orientation toward the sun shifted, about 20,000 years ago, melting the northern hemisphere's large ice sheets.
Could humans survive an ice age : Yes, people just like us lived through the ice age. Since our species, Homo sapiens, emerged about 300,000 years ago in Africa, we have spread around the world. During the ice age, some populations remained in Africa and did not experience the full effects of the cold.
Now the hotly debated question about why mammoths went extinct has been answered – geneticists analysed ancient environmental DNA and proved it was because when the icebergs melted, it became far too wet for the giant animals to survive because their food source – vegetation – was practically wiped out. It was thought that mammoths began to go extinct then but we also found they actually survived beyond the Ice Age all in different regions of the Arctic and into the Holocene — the time that we are currently living in – far longer than scientists realised.
What animals existed in 10,000 BC
Mammoths (at least four different kinds)
Smilodon (saber-toothed cats)
Woolly rhinoceros.
Giant ground sloth.
Elephant bird.
Cave bears.
Irish elk.
Glyptodon.
Scrat, the fictional saber-toothed squirrel from the Ice Age films, may not be so fictional after all.The geological record appears to show that ice ages start when the continents are in positions which block or reduce the flow of warm water from the equator to the poles and thus allow ice sheets to form. The ice sheets increase Earth's reflectivity and thus reduce the absorption of solar radiation. Many of them probably could survive today. Dinosaurs ruled the world for 150 million years, and endured hot and cold spells, volcanic eruptions, and changing sea levels. There is nothing about today's world that would be fatal to them.
What killed the ice age : When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends.
Can the ice age happen again : Instead, Earth's natural cycles and greenhouse effects might delay the onset of the next ice age, expected within the next 10,000 to 100,000 years. Some theories suggest global warming could potentially trigger an ice age by disrupting ocean currents, specifically the Gulf Stream, leading to dramatic cooling in Europe.
Did humans almost go extinct 70,000 years ago
Human ancestors in Africa were pushed to the brink of extinction around 900,000 years ago, a study shows. The work, published in Science, suggests a drastic reduction in the population of our ancestors well before our species, Homo sapiens, emerged. The scientific consensus is that there is a relatively low risk of near-term human extinction due to natural causes. The likelihood of human extinction through humankind's own activities, however, is a current area of research and debate.The revival of the woolly mammoth is a proposed hypothetical that frozen soft-tissue remains and DNA from extinct woolly mammoths could be a means of regenerating the species. Several methods have been proposed to achieve this goal, including cloning, artificial insemination, and genome editing.
Is it possible that mammoths are still alive : Mammoths only remain as fur and bones. If we can reverse the destruction we have caused to the habitats of extant endangered species before they vanish forever, at least they might be able to make a comeback.
