p.s. I also agree with the viewpoint that long term micro-evolution results in eventual macro-evolution as compared to the original ancestor.
Lest we forget that 95% of all prior species and subspecies are now extinct. Almost all modern animals are unrecognizable as compared to their ancestors.
In Creationist theory they speak of missing links. Yes, most of them are dead and disintgrated over millenia of decomposition. There are a few species which are recognizably related to very early species.
Conclusion
Some of the creatures above were believed to be extinct until their discovery revealed otherwise. Our understanding of evolution does not just come from the study of extinct ancestor species, but also through examining those creatures that have barely changed ‘ what hasn’t changed can teach us as much as the study of what has changed. All of these species survived the extinction of the dinosaurs and are still around today. How many more species do we believe to be extinct are still alive and waiting to be discovered?
