The bare mininum intake of water should be at least 64 oz. Now if you live in hotter states like me who live in AZ in the summer months you will want to increase that intake to about 96-128 oz per day. Of course your activity level and how much you spend outside will be a factor as well.
Neanderthals were a separate species from modern humans, and became extinct (because of climate change or interaction with modern humans) and were replaced by modern humans moving into their habitat between 45,000 and 40,000 years ago.
Dinosaurs became extinct about 65 million years ago at the end of the cretaceous period (see what cretaceous dinosaurs were around at this time). About 70% of all animal life on earth died out. Scientists call it a mass extinction â it wasnât the first mass extinction in earthâs history and it probably wonât be the last! Having existed for 165 million years, why did dinosaurs die out? There are many different theories about why this happened.
