A question about our planet?

[danot]

I feel it's fair to say that the earth and the various forms of life which have lived, perished and evolved upon it ever since the moment our earliest encester sprouted legs and crawled out of the sea became what they are due to the earth being how it was and now is. But let's assume things were different . Let's assume that the history of our earth's early events are unaltered, but the water to land mass ratio is and always has been 70% land to 30% water. what affect(if there would be any noticable affect)would this have had on our planet's evolutionary history, technological advances and life as we now know it? Obviously I've already concluded that it would most certainly result in there being fewer fish and chip shops and Harry Ramsdons..... but on a serious level, how would it affect things such as our weather system, humidity, vegitation, wild life and even our own evolutionary history.?

Smaller oceans means less rain and dryer land so less vegetation and fewer animals, that’s assuming life could have evolved with less water.

You have got the land and water ratio round the wrong way, and during the last ice age, where the sea level was around 350 ffeet lower than today, ther was more land. Austrlia lost a land mass due to sea level rise about the size of India.

 

One thing regarding the evolutionary process is that necessity is the driver of change. So its how individuals and species adapt to changing conditions. When times are hard ingenuity might be encouraged more.

 

Pots, for cooking were discovered in China last year dating back 22 thousand years, when Sheffield was under 2 miles of ice, so not much progress ther eat the time.

In the developed countries we lived just as other animals did, scavenging and hunting, living rough, moving as winter set in.

 

We are technically still in an ice age as the poles are still frozen, but if more ice melts on land, and sea levels which are rising about 2-3mm a year, spped up then its estimated a 20-40 foot rise in sea level due to warming of climate. More serious in the next generations life, so lowlands flooded, and farming land lost, people migrating to higher ground.

 

Sounds a nightmare.

Getting the land water ratio the wrong way round was deliberate as I was presenting an alternative, an exact opposite if you like to what the ratio actually is. The points you make are very interesting if what you say is correct.
