Biology is not lineage specific:
Evolution expects the species to fall into a common descent pattern. Therefore a particular lineage should not have highly differentiated, unique and complex designs, when compared to neighboring species. But this has been increasingly found to be the case, so much so that this pattern now has its own name—lineage-specific biology.
For example, transcription factors are proteins that bind to DNA and regulate which genes are expressed. Yet despite the importance of these proteins, their DNA binding sites vary dramatically across different species. As one report explained, “It was widely assumed that, like the sequences of the genes themselves, these transcription factor binding sites would be highly conserved throughout evolution. However, this turns out not to be the case in mammals.” (Rewiring of gene regulation across 300 million years of evolution) Evolutionists were surprised when transcription factor binding sites were found to be not conserved between mice and men, (Kunarso et. al.) between various other vertebrates, and even between different species of yeast. So now evolution is believed to have performed a massive, lineage-specific “rewiring” of cellular regulatory networks. (Pennacchio and Visel)
There are many more such examples of lineage-specific biology. Although flowers have four basic parts: sepals, petals, stamens and carpels, the daffodil’s trumpet is fundamentally different and must be an evolutionary “novelty.” (Oxford scientists say trumpets in daffodils are ‘new organ’) Out of the thousands of cockroach species, Saltoblattella montistabularis from South Africa is the only one that leaps. With its spring-loaded hind legs it accelerates at 23 g’s and out jumps even grass hoppers. (Picker, Colville and Burrows) An important immune system component, which is highly conserved across the vertebrates, is mysteriously absent in the Atlantic cod, Gadus morhua. (Star, et. al.) The brown algae, Ectocarpus siliculosus, has unique enzymes for biosynthesis and other tasks. (Cock) And the algae Bigelowiella natans has ten thousand unique genes and highly complex gene splicing machinery never before seen in a unicellular organism. It is, as one evolutionist explained, “unprecedented and truly remarkable for a unicellular organism.” (Tiny algae shed light on photosynthesis as a dynamic property)
Another fascinating example of lineage-specific biology are the many peculiar morphological and molecular novelties found in disparate, unrelated unicellular protists. As one study concluded, “Both euglenozoans and alveolates have a reputation for ‘doing things their own way,’ which is to say that they have developed seemingly unique ways to build important cellular structures or carry out molecular tasks critical for their survival. Why such hotspots for the evolution of novel solutions to problems should exist in the tree of life is not entirely clear.” (Lukes, Leander and Keeling, 2009a) Or as one evolutionist exclaimed, “this is totally crazy.” (Lukes, Leander and Keeling, 2009b)
