No entirely new features have evolved (Talk.Origins)
From CreationWiki, the encyclopedia of creation science
No entirely new features or biological functions have evolved.
(Talk.Origins quotes in blue)
1. Most, if not all, "entirely new features" are modifications of previously existing features. Bird wings, for example, are modified tetrapod forelimbs, which are modified sarcopterygian pectoral fins. A complex, entirely new feature, appearing out of nowhere, would be evidence for creationism.Talk Origins is assuming that Evolution has occurred, forming bird wings from tetrapod forelimbs, and tetrapod forelimbs from sarcopterygian pectoral fins. This is exactly what the claim says does not happen and has not happened.
Talk Origins is also understating the problems of going from fins to forelimbs to wings. In each case the new version is far more than a modified version of the old; instead there has been an increase in complexity.
2. New features have evolved from older different features. There are several examples of microorganisms evolving the ability to degrade or metabolize novel manmade compounds:
- arsenobetaine degradation.
- naphthalene and related compound degradation.
- chlorocatechol degradation.
- 2,4-dinitrotolule degradation.
These are probably examples of Natural Genetic Engineering rather than mutations, but still in each case they clearly represent modifications of existing cell functions to adapt to new environmental conditions. Creationism predicts this type of change.
These microorganisms seem to have the ability to produce new enzymes and proteins to deal with specific biological and chemical situations. This is not the evolution of something new but rather the work of an existing ability.
Also, a unicellular organism has been evolved to form multicellular colonies (Boraas et al. 1998); see also mutations producing new features.
This is nothing of the kind. The formation of colonies of single cell organisms is nothing new, and that is all that is illustrated here. The data is consistent with a pre-existing ability of this unicellular green alga to form colonies when it aids their survival. No genetic comparison was done between the colonies and the separate cells to show a mutation; it is simply assumed.
3. An arbitrary genetic sequence can evolve to acquire functionality (Hayashi et al. 2003).
Not only was the “arbitrary” genetic sequence fused with an existing functional sequence, but was taken from another functional sequence. The only thing arbitrary was the selection of the genetic sequence. The new sequence may simply contain information that the organism was able to use. That said, it is also possible that the new sequence simply provided extra space for storing the results of Natural Genetic Engineering.
