The Tree of Life Collapsing
"In the 1990s, research into the genetic codes of living things worsened the quandary faced by the theory of evolution in this regard. In these experiments, instead of the earlier comparisons that were limited to protein sequences, "ribosomal RNA" (rRNA) sequences were compared. From these findings, evolutionist scientists sought to establish an "evolutionary tree." However, they were disappointed by the results.
It has been very difficult to root the entire tree of life. This is perhaps the only "true" hole that does exist in the theory. The problem is in identifying which differences are due to horizontal gene transfer and vertical gene transfer, or if these distinctions can even be used to root the entire tree. Scientists are still trying to describe a genetic common ancestor for prokaryotes and eukaryotes. However, they have had no problems describing a common ancestor between humans and chimps.
The problem is that this article does nothing to refute the evidence supporting common ancestry of all apes (including humans), all primates, all mammals, and all vertebrates. Thes evolutionary distances are denied by creationists, and the evidence you have presented does not support your case.
[FONT=Verdana, Arial, Helvetica, sans-serif]The Archaeopteryx Misconception[/FONT]
In response to the question whether there is any fossil evidence for "reptile-bird evolution," evolutionists pronounce the name of one single creature. This is the fossil of a bird called Archaeopteryx, one of the most widely known so-called transitional forms among the very few that evolutionists still defend.
Archaeopteryx, the so-called ancestor of modern birds according to evolutionists, lived approximately 150 million years ago. The theory holds that some small dinosaurs, such as Velociraptors or Dromaeosaurs, evolved by acquiring wings and then starting to fly. Thus, Archaeopteryx is assumed to be a transitional form that branched off from its dinosaur ancestors and started to fly for the first time.
However, the latest studies of Archaeopteryx fossils indicate that this explanation lacks any scientific foundation. This is absolutely not a transitional form, but an extinct species of bird, having some insignificant differences from modern birds.
There are many, many misconceptions in this article. First, it was not flight first, then feathers. Recent fossil finds include non-flying dinosaurs with feathers. Many creationists forget the first function that feathers serve in birds--insulation. Feathers also play an important role in courtship rituals. Feathers could have played the same roles in these non-flying feathered dinosaurs.
Secondly, the features that Archaeopteryx does not share with modern birds it does share with dinosaurs. That's right, Archie has both dinosaur not found in birds and bird features not found in non-avian dinosaurs. Archie is, by definition, an intermediate fossil.
Does the human embryo go through stages of evolution?
No, it goes through stages of development. However, some of these stages do reflect human ancestry. For example, the human embryo has a tail.
Quick-read this article:
The idea that the human embryo retraces the stages of evolution has been exposed as false for many years. Yet the idea persists.
While it is unfortunate that the idea persists, the idea was never a part of the theory of evolution.
The human embryo is human from the moment of conception, and shows no evidence of evolution.
I didn't know that humans were single celled organisms.
The human embryo is also a primate from the moment of conception, hence the tail.
The human embryo is also a vertebrate just like fish, hence the pharyngeal pouches that form the larynx in terrestrial vertebrates and the gill arches in fish.
The human embryo is also a derived reptile (aka mammal), so the embryo starts with three jaw bones, two of which move into the middle ear just as we see in the transitional fossil series in the fossil record.
Does embryonic development directly recapitulate the evolution of it's ancestors? Absolutely not. Does embryonic development REFLECT the evolution of it's ancestors? Absolutely YES!!
