If Ice age Never Happened.

Ice age


In thick sheets of ice and sea levels so low you could walk to a different continent, this what our planet would look like during an iceage there have been five of them in Earth's history and they've had a huge impact on our present world, now try and imagine Earth where these ice ages age has never existed in the first place what ecosystem would change would humans have evolved and why do ice ages happen. Over a Century ago milutin Milankovitch hypothesize that changes in the Earth's orbit the angle of its axis and the direction of its axis are what create long-term changes to the climate known as Milankovitch cycles they create the seasons we know well and the ice ages that we're glad to have, but what if Milankovitch cycles didn't exist like without Milankovitch cycles would look a lot different have been no ice ages not at all ages not at all which means no glaciers to carve out beautiful Inland Lakes and valleys it also means Earth flora and fauna would have evolved differently.


Grasses



Grasses initially popped up on Earth before the first ice age but they truly thrived as the Earth became cooler and drier, grasslands, Savannah's grew all over the Earth replacing dense forest with no cooling. period leading up to the first ice age glasses would not have spread so easily there would be less variety and the animals that evolved to eat grass would be less abundant horses giraffes cows gazelles any animal you associate with dry grasslands would have had left habitat Instead there would be more rain forests left on Earth the climate in general would be warmer and wetter and what about the animals that rains during the ice ages well we wouldn't know of any sabertooth cats giant sloths mastodons woolly mammoth mammoths probably would never have graced our planet but what about us homoerectus first emerged during the last big ice age in the pleistocene epic this is the same time that woolly mammoths roamed the world a general hypothesis is that the extreme climate forced the evolution of homo erectus they had change their diets from Mostly plants to have plants and 1/2 meat and 1/2 meat which increased their brain size they developed the use of tools and they had to migrate to see more hospitable land without the Ice Age forcing the need for adaptation and evolution humans would probably not exist which also means our present Earth wouldn't have any of the human human-induced climate change changes were witnessing today even if Homoerectus which precedeed Homo sapiens evolved regardless of the Ice Age our progress as a species would change many scientists attribute agriculture to the rapid growth in global expansion of humans but without the Ice Age we could have developed the benefits of Agriculture sooner in the absence of dry air a grasslands we also might have advanced different farming practices which favoured Forest Foods our diet might consist of fewer plants from the grass family like wheat and oats and more fruits and least for evolution to occur it needs a catalyst like Ice Age Earth as we know it today exists because cycles and catalyst have pushed livingto that it would be a very different planet without Milankovitch cycles in the ice ages they produce than than this.
