LightGigantic:
surely you don't suggest that the fossil record has lent itself to anything close to a singular consensus - just consider the variety of interpretation that has been read into the fossil record over the past 50 years (considering it often alludes to substantiating 'observations' many hundreds of thousands of years ago
There has been some varying viewpoints in the fossil record over specific fossils, but the majority of biologists tend to agree that the evolutionary record is strongly presupposed in the available fossil record, especially through the well-known lineage-creatures, such as the aforementioned ascent of man and the species preceding many common animals, like the horse.
"We really don't know what the Earth was like three or four billion years ago. So there are all sorts of theories and speculations. The major uncertainty concerns what the atmosphere was like. This is a major area of dispute" Stanley Miller
As far as I am aware, recent evidence is rather conclusive on what we would expect an early Earth to have. Moreover, we are finding direct evidence of planetary disks right now in space, which could in the future show what would be the likely composition of that rocky planets like Earth.
intelligence is not behind my use of the screw driver as both a chisel and lever?
Certainly, your actions betray an intelligent cause. However, were you a designer of a living creature, presumably you'd want to remove the extraneous parts that serve no purpose.
For example: To build a house from a bridge, I'd remove the cables of the bridge, or at the very least, employ them for a totally different reason.
Is this logical?
A x time = A1
B x time = B1
therefore B1=A1
Not at all.
However, let us discuss something like this.
Ducks branched off from loons.
Neoduck branches off from ducks.
Neo-neo duck branches off from neo-ducks.
neo99-duck branches off from neo98-ducks, by which time it has scales, is 20 feet tall, and its wings have grown hands and can talk.
By this time, surely the comparative neo99-loon would be so remarkably different, that it would be the equivalent of judging the difference between a caterpillar and a dog, yes?
for that to be logical one would need evidence of inter genus movement - hence it remains theoretical
At present, a big example of this is the move from dinosaurs to birds. There are several famous dinosaur species that show explicitly avian features.
Thats my point - Things that could theoretically be true remain theories (at best)
just because one can synthesize the chemicals that life utilizes does not mean one has made any substantial progress in synthesizing life
This may be cleared up within fifty years, but I shall concede that there is so far no experimental proof showing that abiogenesis is possible, only very likely, owing to said amino acid production.
