“Gene Jumping” And Evolution

While various religions cling to notions their unique gods formed the universe, science continues to unravel mysteries of how we came to be here. A new thing I read about is gene jumping. It is that some genes in the make up of living creatures such as ourselves did not come from parent to offspring but moved horizontally from creatures of separate species. One fourth of the genes of cud chewing animals, i.e. cows, are shared with and seemed to have come from reptiles.

The origin of some genes is not known. Neither is exactly how they ended up in other creatures. One idea is insects exacted blood from one species and left some in another.

The gene studied, “Bovb,” is thought to have jumped between species at least eleven times. When the new host species had its DNA changed by the new cell, it is thought the evolutionary path must surely have been altered.

Investigation has also found genes change over time. Thus, a gene that appears today in different species is often different from the same gene in species of more distant relatives.

Evolution often involves drawing family trees. When scientists draw plot the species who share Bovb the drawing is a complicated maze of horizontal relationships.

Parts of Christianity have vigorously argued against the field of evolution saying there are various questions which remain unanswered. Certainly not everything is known.

That evolution did not always have a continuous and straight path but rather fast changes periodically may be explained eventually.

    “Gene Jumping”.huh?. That’s a new one on me too. No, wait a minute, It sounds like “punctuated equilibria” which was postulated by a Harvard paleontologist after admitting that there is no evidence in the fossil record for evolution. Evolution “scientists” are blind guides leading the blind like yourself heading into the ditch.

        I doubt the idiots have the capability to understand anything about transposons AKA “junk DNA” or “jumping genes”. They lack intellectual curiosity to question life around them as well as poor scientific knowledge, thus destroying their credibility in such matters. Transposons have been known since the 1980’s but their significance was not realized until the advances in molecular genetics in the last 10 to 15 years. Stay stupid and don’t read it.

      Ross: there is no evidence in the fossil record for evolution.

      Exactly the opposite, of course, or there would be no changes in the fossil record.

        wise up grandma. I have been told by experts in the field that the so-called fossil record is rather problematic: evolutionary biologists now longer rely on it to the extent that they once did. we now have DNA and all that.

        1. Grandma

          Duh… Of course the fossil record is somewhat problematic, because not everything got fossilized and not everything has been found. Besides, when a “missing link” fossil is found the creationists will say that while one gap has been closed two more have been opened, which is not the case at all. These “experts” should have told you that the evolution of therapsid reptiles has been documented through fossils because DNA simply can’t be recovered from that far back. Also, gene researchers and fossil researchers are working together to continue fine-tuning…

      Ross. Here’s an online definition: Punctuated equilibrium is a theory describing an evolutionary change that occurs rapidly and in brief geological events in between the long periods of stasis (or equilibrium). The theory is based on the stasis in fossil records, and when phenotypic evolution occurs, it is localized in rare, rapid events of branching speciation. Accordingly, the theory assumes that when there is a significant evolutionary change, cladogenesis occurs. Cladogenesis is the process where a species splits into two distinct spcies instead of one species transforming into another over time.1 The American paleontologists Niles Eldredge and Stephen Jay Gould first proposed the theory in 1972. They referred to it as punctuated equilibria.2 This theory is presented to contrast phyletic gradualism. In the latter, evolution is described to happen smoothly and continuously (anagenesis).

      I should add that when Eldridge and Gould wrote that original 3 page paper they were discussing species change in snails.

        pardon my assumed stupidity but, in your mind, does PE explain the rather sudden emergence of a self-conscientious primate. and has the PE “theory” been challenged by what you would accept as “reputable” scientists?
