I had the great pleasure of living for several years in central Texas and took all the geology classes I could find in the area. We lived on ground laid down during the Cretaceous period; at the time it was formed, it was a sea, so there were all kinds of fossil gastropods, echinoids,  trilobites, brachiopods, bivalves, sponges, and other invertebrates.

Underlaying that layer were pre-cambrian rock at the deepest layers with outcroppings poking up through the upper layers. It had no fossils because flora and fauna had not developed yet. There were igneous outcroppings, beautiful metamorphic rocks, geologic structures, and complex landforms, and sedimentary clays overlaid everything except in river cuts, where we found ancient  fossils.  I found sharks teeth in the Devonian.
The shoreline shifted back and forth many times, leaving behind a record of both marine and non-marine flora and fauna. These layers  containe a rich fossil record including dinosaurs, other reptiles, amphibians, birds, fish, and mammals. There were ammonites as big as six feet across but they fell apart when I dug them. I have many smaller ones. 

By comparing sharks teeth from the Devonian, on up through the Permian, Triassic shales, and Jurassic, fossils were in the river cuts, and the Cretaceous overlaid it all. 

The point of all this is that the changes of each flora and fauna could be tracked from oldest to youngest over millions of years. Devonian was 360-410 million years ago, the Cretaceous was 66-138 million years ago. 

Chris, can you even imagine the time it took to go from no fossils in the pre-cambrian, and the development of plants and flowers, and sea creatures over time? 

There was no designer, no planner, no creator of all this. Things just grew, kind of like things grow in the refrigerator or in the vegetable bin if left unattended. Cells divide, mix with bacteria and molds, and who knows what all else is there, but they just change, cell by cell, day by day, and in the case of the geologic time scale, over millions of years. 

Do you have any idea how long it took the black skin of Africans to evolve into white skins, blond hair and blue eyes? It didn't happen in a generation or a thousand years .. it took thousands and thousands of years. And the Africa migration that turned east out of Africa toward Asia developed characteristics we now know as Asian or Oriental. We all come from ooze in Africa. We are all made of the same stuff. We all look at the same stars and moon and sun. 

Human change didn't come because of eugenics, it came from natural selection of those creatures that survived to give birth to the next generations. Eugenics is a human made device to "cleanse" one group from another, but when that happens the cleansing is of our cousins. We destroy our own kind.

A simple Google search sheds light on what, exactly, is the Stanford Who's Who list.  It's basically an online networking site for professionals (and "professionals") which you can join simply by paying their listing fee.  If you read through some of the Google search articles you can see that the Who's Who list comes with a lot of questionable baggage and business practices.  'Nuff said.

Dear Mr Tidman

 I thought that I had evolved faster and was peculiar in some way.


You are half right.


Best regards, F.

Chris. They can hear your thoughts, man. Adjust your tinfoil hat.

Is the Christ Id Man show still on?

 

Well, he flat-out admitted that he's a Creationist.  His statements about Evolution just demonstrate that he's learned very little beyond some Creationist straw-man.

It's like I've told the one or two religious nuts that we have in my department at work:  if you want to know about Evolution, you don't learn it from some preacher who's lying about it to turn you into a fundamentalist nut.  You learn it from an evolutionary biologist.  I've been loaning out by copy of 'The Greatest Show on Earth'.

Chris apparently needs to learn that lesson.

I'm going to second what The Flying Atheist says, with one huge caveat.

"In Our Time" fails utterly when talking modern(ish) science.  History of science - no problem.  The cultural significance of "Waiting for Godot" - no problem.  Feminist readings of Marxian geography, with particular reference to Detroit gangland culture - no problem.

I don't recall the exact episode  - there was some very well spoken woman trying to discuss (light bulb filaments?   Magnets (how the frack do they work?) ?.  Space travel? - I forget what exactly) and it was so abysmally ill-informed, I never listened again.  

It was like "In Our Time" was a series of lectures on science, presented by C. Tidman.

@Fred Trellis

An interesting coincidence that you bring up the name Lamarck.  Earlier today I listened to an old podcasts from 2003 of "In Our Time" from BBC Radio with Melvyn Bragg.  The topic discussed with his three panelists was "Jean-Baptiste Lamarck and Natural Selection."

Podcast info here:  Lamarck and Natural Selection

Podcast player:  http://www.bbc.co.uk/iplayer/console/p005495d

For everyone:  if you're not familiar with the "In Our Time" program, you should check it out.  Every episode is an interesting discussion with Melvyn Bragg and three scholars.  Topics vary from history, science, religion, cultural...everything...old and new.  I was introduced to it last year and am in the process of listening to past years' episodes.  I just finished the year 2003!!  Great stuff.

@tidman.

This is the third comment you have made which suggests you do not understand the current synthesis that is evolutionary theory.  You are investing the individual with an evolutionary effect or significance the individual simply does not have individually as an individual individual.  As an individual in a group - yes.  As an individual on their own - no.
