ever heard of Dr Baugh and his hyperbaric biosphere?

Does this disprove evolution or does the atmospheric change have nothing to do with a god?

Dr Baugh says the dinosaurs couldn't possible breathe with todays oxygen because of their small rib cages or somthing.... I don't remeber.

Answer 1

There are many animals still alive today which lived in that environment back then. Crocodiles are closely related to what dinosaurs were like during prehistoric times. Turtles have also not evolved very much since those times. Birds are descendant from dinosaurs and have no trouble breathing the high O2 atmosphere. In fact, the require more O2 than we do, because of the metabolic demands of flight. Therefore, they have developed two lung chambers to help them attain more oxygen. Anyway, I don't believe the atmosphere was different then. The climate was different. It was warmer and wetter. Antarctica had not shifted to the south pole yet to open up the Indian Ocean currents which would later cool the earth.

Answer 2

In that time (lets say 64Mio years ago) the earth was coverd with huge forrests. but the ancient kind of plants were less effectiv onphotosynthesis. So they were not able to reduce the same ammount of CO2 as modern plants do. We can say the atmosphere had a much higher Carbondioxid concentration. Further it was warmer and more arrid (means dry). but you would have no problems after crusing with a time machine ;)

Answer 3

substantial one i think of is the effect of a meteorite that created a cloud around the Earth for years, sunlight grew to become into obliterated , to that end chilly, and environment all dusty . flora died so no nutrition for animals ,,, looks the main clever to me

Answer 4

1st of all, we're talking about a span of 300 million years here.

Dinosaurs died out about 75 millions years ago and were here for about 250 million years. So we are certainly talking about many ice ages, a couple of major die-offs, and many other changes.

(very detailed)

Answer 5

I heard it was warmer, wetter, and the gasses were a different balance.
