Salty meal --> digestive process --> hypertonic blood plasma --> hypertonic intestinal fluid --> pulls H2O from cells --> increase in blood plasma volume --> increase in blood pressure and increase in thirst --> increase of urine in the kidneys.
Dinosaurs lived between 230 and 65 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous. During this time, the land gradually split up from one huge continent into smaller ones. The associated changes in the climate and vegetation affected how dinosaurs evolved.
So, as you can see, there was a long time that passed between when the dinosaurs went extinct and when humans were around (about 62.5 million years). However, our species, Homo sapiens, did not exist until about 0.25 million years ago (250,000 years).
