Blood clotting – Surprising degree of repeated evolution in vertebrates and invertebrates
Hello? Darwinians ? Why is everything so surprising? from a mainstream paper: Recent delineation of the serine protease cascade controlling dorsal–ventral patterning during Drosophila embryogenesis…
Comments closedRepeated evolution of Myelin – a sheath of multilayered membranes around nerves nodes.
Current concepts of invertebrate phylogeny are reviewed. Annelida and Arthropoda, previously regarded as closely related, are now placed in separate clades. Myelin, a sheath of…
Comments closedRepeated Evolution Versus Common Ancestry
from a mainstream paper: Why sex chromosomes turn over and remain undifferentiated in some taxa, whereas they degenerate in others, is still an area of…
Comments closedRepeated evolution of super-vision shakes up the dogma of deep-sea vision
I will repeat myself again, but i have to say it one more time – it is not easy to understand how natural selection works.…
Comments closedRepeated evolution: same pseudogenes evolved independently in human and non-human primate lineages
What is left of common ancestry and shared DNA errors ? A pseudogene is defined to be a gene that has lost its function, especially…
Comments closedRepeated evolution: 11 Mitochondrial Genes in Deep-Sea Fishes changed the same way independently
The adaptive evolution of the mtDNA may reflect that aerobic metabolism plays a more important role than anaerobic metabolism in deep-sea fishes, whose energy sources…
Comments closedRepeated evolution: The same mutation occurred 20 times independently in fishes’ light-sensitive eye-protein.
Here we show that a missense mutation in rhodopsin (Phe261Tyr) is an adaptation to the red-shifted Baltic Sea light environment. The transition from phenylalanine to…
Comments closedSurprising repeated devolution: Various species lineages lost teeth independently, despite crucial role of teeth in species survival
i will repeat myself yet again: it is not easy to understand how natural selection works … even the researcher below is quite surprised (these…
Comments closedRepeated evolution: Webbed foot evolved many times independently
The webbed foot is a specialized limb present in a variety of vertebrates that aids in locomotion. This adaptation is primarily found in semi-aquatic species, and has convergently…
