Typical adaptations seen among animals that live exclusively in caves include: Lack of pigmentation. Reduction in the size of eyes (or absence of eyes altogether) Development of sensory mechanisms that do not depend on light for detecting food or predators.

Researchers said on Thursday that the red brittle star, called Ophiocoma wendtii, is only the second creature known to be able to see without having eyes – known as extraocular vision – joining a single species of sea urchin.

Animals that have completely adapted to cave life include: cave fish, cave crayfish, cave shrimp, isopods, amphipods, millipedes, some cave salamanders and insects.

From the Ice Age onwards, Dr O’Regan found evidence of bears (alive or dead) at 85 places in England and Scotland, from the Stone Age to post-Medieval times. Bears were scarce in Scotland, Wales and the East Midlands, but more frequently found in Yorkshire, the east, the south and London.

So, just how big was it? The Woolly Mammoth was one of the largest land mammals EVER. They were around 4 metres in length and weighed up to 7 tons. That means a Mammoth was the same length as a London bus and weighed the same as two medium sized cars!

Stone Age animals include, the Andrewsarchus, Chalicotherium, Dinohyus, Glyptodon, Indricotherium, Mastodon and Megatherium. The most commonly known include, the Sabre-toothed cat, the Mammoth and the Woolly Rhinoceros. Stone Age animals closest living relatives range from the Elephant to the Sloth!

Originally Answered: How will humankind survive in the next ice age? We won’t. We are currently in the middle of an Ice age, using the scientific definition. The next one is unlikely to be for 10s or 100s of millions of years, by which time we will be extinct, or have evolved too much to be called human.

Researchers used data on Earth’s orbit to find the historical warm interglacial period that looks most like the current one and from this have predicted that the next ice age would usually begin within 1,500 years. They go on to predict that emissions have been so high that it will not.

Scientists call this ice age the Pleistocene Ice Age. It has been going on since about 2.5 million years ago (and some think that it’s actually part of an even longer ice age that started as many as 40 million years ago). We are probably living in an ice age right now!

During the last ice age, which finished about 12,000 years ago, enormous ice masses covered huge swathes of land now inhabited by millions of people. Canada and the northern USA were completely covered in ice, as was the whole of northern Europe and northern Asia.
