RE: “I am still waiting for that proof on macro-evolution.”

Sometimes, I’ll see a comment thread that’s just so rich I feel like sharing it with the rest of the world.

I suppose that’s what blogs are for.

In response to the statement, “I am still waiting for that proof on macro-evolution” by The Maverick Christian, Aaron R. had this to say:

Scientists do not prove things – proof only exists in the context of mathematics – but are convinced by the evidence. There are so many converging lines of evidence that I will not list them here. I doubt that you could even imimate an understanding of, say, polyploidy, so why waste too much time on you.

Creationists make it seem as though there’s some kind of line between micro & macro evolution, when in fact they’re both just two points on the same spectrum, just in different places. There’s no barrier evolution has to overcome in order to cross over into macro-evolution.

You being a creationist, you’ll just reject all the evidence in these research papers.

The Maverick Christian responds:

“I do know what polypoidy is and it is pretty arrogant to think that a creationist is so stupid as to not know. Just because we believe in a divine creator does not mean we don’t know what is written and said in the scientific community.That just show the kind of mentality you have and you show what you truly think of people who don’t follow the standard line of evolution. And I am still waiting for the fossil evidence of what I am asking. those papers don’t prove that.

Finally, Aaron R. responds:

I’m shocked you could read that many pages and words in a 9 minute time period and concluded it didn’t speak about fossils.

In relation to fossils: Fossils give evidence of evolution in a number of ways.

1. The depths of layers in the soil give us an indication of the relative age of the different fossils (“this fossil is older than that one”).

2. The dating of rocks found in the same layers as the fossils gives us an indication of the absolute age (“this fossil is about 50 million years old, and that one is about 55 million years old”).

3. The geographic location of the fossil is important to establish possible geneology. E.g. if we were to find horse fossils in Australia, or kangaroo fossils in Europe, then that would destroy any picture we have of evolution.

4. The types of other fossils we find in the same layers tells us about the environment in which they were living … was it a coral reef, or a tropical forest, or an icy tundra with deciduous bushes.

5. The relative structures of a sequence of fossils, found in the same geographic area, same environment, and sequential layers of soil … gives us evidence of a progression of species from ancestors to descendants. The more fossils we find, the more we can fill out the family tree.  E.g. reptile-birds, reptile-mammals, legged whales, legged sea cows.

We have the fossil of the evolution of the horse from Mesohippus through Equus which clearly shows the transition of a dog-sized animal that had a primitive short face, with eye sockets in the middle and a short diastema (the space between the front teeth and the cheek teeth). Although it has low-crowned teeth, we see the beginnings of the characteristic horse-like ridges on the molars.

For human evolution, we have a large number of fossils in the record such as the australopithecines species. The australopithecine species that is best represented in the fossil record is Australopithecus afarensis with more than one hundred fossil individuals represented found from Northern Ethiopia to Kenya, and South Africa. We can see it’s craniodental features and skeletal morphology and locomotion.

There are many, many more examples.

Even if we didn’t find any fossil, Evolution would still be strongly supported by other means of research such as genetics, molecular evidence, proteins, homology, embryology, bacteriology, pest-control.

The Internet is a magical place.
