Genetic engineering has shown the connection between the fins and hand
The technology of gene editing is a useful topic in medicine. Most genetic engineering is still associated with conventional medical practice, at least so it turns out. Scientists from the University of Chicago used CRISPR to identify key evolutionary relationship between the fin and the arm. The researchers altered the genes of fish-zebras, which are responsible for the fins so that certain cells began to glow. Further, they found after observing the glow that glow almost fin and fingers a similar. In other words, there is a very great similarity between genes that govern the fins and fingers.
The discovery suggests that the differences between fins and hands could be, rooted in the tissues and the bones of distinctly different fish and people. This, in turn, helps to explain the intermediate types where the fins grew, as it were, of limbs. You can also say that CRISPR gives hope for the discovery of another evolutionary patterns. Possible aspects of biological development of various types that are still a mystery, will soon open its secrets to scientists.
