Question

How might life in the Americas have been different if the Ice Ages had not occurred?

Answer 1

Answer:

Without the ice ages dropping sea levels it’s doubtful if North America would’ve been populated when the Europeans arrived, Other than the few Pacific Islanders who rafted to Chile and the handful of Norsemen who wandered onto Nova Scotia and a few Inuits.

Answer 2

Answer:

• Consider the Earth buried in several feet of ice. Also, the sea levels were so low that you could walk to another continent. This is how an ice age might manifest on our globe.
• Grass first appeared on Earth prior to the first glacial age. But when the Earth got colder and drier, they really flourished.
• All over the Earth, grasslands, tundras, and savannahs proliferated in place of dense forests.
• Mastodons, woolly mammoths, sabre-toothed cats, and enormous sloths probably never would have existed on our planet.
• Humans probably wouldn't exist if the cold era hadn't forced the necessity for adaptation and evolution.
• Many experts credit the fast rise and globalisation of mankind to agriculture. But had there not been an ice age, agriculture's advantages might have been realised sooner.
• In the absence of arid, dry grasslands, we might not have developed new farming techniques that favoured crops from the forest. We might eat fewer members of the grass family of plants, such as wheat and oats, and more fruits and vegetables.
• A catalyst, such as an ice age, is necessary for evolution to take place.
