Evolution: life has evolved to evolve: comment on "How life changes itself: the Read-Write (RW) genome" by James Shapiro.
Jim Shapiro synthesizes a great many observations about the mechanisms of evolution to reach the remarkable conclusion that large‐scale modification, exchange, and rearrangement of the genome are common and should be viewed as fundamental features of life [1]. In other words, the genome should be viewed not as mostly read‐only with a few rare mutations, but rather as a fully‐fledged read‐write ...
متن کاملWhy Ubiquitin Has Not Evolved
Ubiquitin, discovered less than 50 years ago, tags thousands of diseased proteins for destruction. It is small (only 76 amino acids), and is found unchanged in mammals, birds, fish, and even worms, indicating that ubiquitin is perfect. Key features of its functionality are identified here using critical point thermodynamic scaling theory. These include synchronized pivots and hinges, a stabiliz...
متن کاملLanguage Has Evolved to Depend on Multiple-Cue Integration
Recent research on language evolution suggests that language to a large extent has been shaped by cultural evolution to fit domain-general constraints deriving from the human brain. An implication of this view is that much of the neural hardware involved in language is not specific to it. This means that language has to be acquired largely by mechanisms that are not uniquely dedicated for this ...
متن کاملEvolution Programs Evolved
Growth grammars in the form of parallel rewrite systems (Lsystems) are used to model morphogenetic processes of plant structures. With the help of evolutionary programming techniques developmental programs are bred which encode plants that exhibit characteristic growth patterns advantageous in competitive environments. Program evolution is demonstrated on the basis of extended genetic programmi...
متن کاملColoniality has evolved once in Stolidobranch Ascidians.
Ascidians exhibit a rich array of body plans and life history strategies. Colonial species typically consist of zooids embedded in a common test and brood large, fully developed larvae, while solitary species live singly and usually free-spawn eggs that develop into small, undifferentiated larvae. Ascidians in the order Stolidobranchia include both colonial and solitary species, as well as seve...
