Similarities between genomes has been so important for evolutionary science, it’s focus has been unreal through the years. On the other hand, evolutionary scientists paid little attention to “Orphan Genes” which present major problems for evolution because these genes have no evolutionary homology or kinship to genes from other lineages.
How do evolutionists explain animals who acquire these orphan genes? Where did they come from? They begin by sounding like creationists but instead of a brilliant designer, it’s the “genus” unthinking process which they claim is fine tuning the genes. Not surprising, skipping the origin part using phrases like “origins are often obscure” and “have most likely originated within the class.”
One asks again, where did these particular unique genes come from? Science Daily could only hope it would lead to a better understanding of evolution. In reality, they have no idea, but it even they make it sound miraculous in it’s emergence …Looking at the science paper, they claim…
“Our data indicate that novel genes may play a role in the creation of novel morphological features, thus representing one way how evolution works at the genus level. Appearance of novel genes may reflect evolutionary processes that allow animals to adapt in the best way to changing environmental conditions and new habitats.”
“The data provide experimental support for the hypothesis that novel genes are involved in specific ecological adaptations that change over time and that such genes serve as the raw material for microevolutionary divergence…” PLoS Biology
How common are orphan genes? With little study done on these particular genes, they found bacterial genomes have an abundance of these genes without homologs. Science Daily claims…
“However, every group of animals also possesses a small proportion of genes which are, in contrary, extremely variable among closely related species or even unique. For example, a gene may be present in one species or animal group, but not in any other.”
Evolution relies so heavily on genes passing on to one species to the next, but unique genes found in one animal and not in any other animal. Do you know what that means? Think! It’s showing evidence for the creationist model which states animals have limited variations within it’s own kind. Maybe this is one of the reasons why evolutionary scientists have had little interest in studying orphan genes through the years!
