LOWER FITNESS. "There are no reports of reversed southern flounder in nature, though we show 16% reversal when this species is raised in the laboratory. This suggests that reversed (dextral) southern flounder have low survival in nature, but enhanced survival in the laboratory when they are identified early and segregated from their sinistral siblings." https://lnkd.in/d9EMwRb View in LinkedIn

REVERSE MORPH FREQUENCY. "The proportion of flatfish displaying reversed morphology and behavior in a natural population varies among species from virtually none in the tonguefishes (Cynoglosidae) to as high as 100% in some starry flounder." https://lnkd.in/d9EMwRb View in LinkedIn

FLOUNDER MORPH DIFFERENCES. "In parallel, significant differences in feeding choices were detected, suggesting a coherent association between subtle morphological differences between morphs and their use of trophic resources." https://lnkd.in/d6Bcfrh View in LinkedIn

FLIP-FLOPPER. "We examined the case of Platichthys flesus (flounder), a polymorphic flatfish exhibiting large and clinal variation in the frequency of the left-sided morph, which is the reversed condition in this generally right-sided species. Morphological differences were observed between morphs, which are in agreement with previous findings in a congeneric species (Platichthys stellatus)." https://lnkd.in/d6Bcfrh View in LinkedIn

"SIDEDNESS POLYMORPHISM in flatfish has been linked to ecological selection between morphs. However, the alternate hypothesis that morphological differences between right- and left-sided forms may be due to errors during development, as a consequence of disturbed homeostasis, which still remains largely unexplored." https://lnkd.in/d6Bcfrh View in LinkedIn

MALWARE. "Malicious programmers have sought to protect their encrypted code from this virus-scanning strategy by rewriting the unencrypted decryption engine (and the resulting encrypted payload) each time the virus or worm is propagated. Anti-virus software uses sophisticated pattern analysis to find underlying patterns within the different mutations of the decryption engine, in hopes of reliably detecting such malware." https://lnkd.in/dZPjiRS View in LinkedIn

THYROID HORMONE DISRUPTERS. "Chemical disruption of the thyroid axis using thiourea or methimazole (MMI) delays or stops stomach development in the Japanese flounder (Paralichthys olivaceus) and otolith mineralization in the Southern flounder (Paralichthys lethostigma). The importance of thyroid hormones during metamorphosis is further emphasized in other flatfish species where they have been shown to be important for the maturation of the muscle, stomach and skin." https://lnkd.in/du68ipH View in LinkedIn

POLYMORPHIC CODE. "In computer terminology, polymorphic code is code that uses a polymorphic engine to mutate while keeping the original algorithm intact. That is, the code changes itself each time it runs, but the function of the code (its semantics) will not change at all. For example, 1+3 and 6-2 both achieve the same result while using different code. This technique is sometimes used by computer viruses, shellcodes and computer worms to hide their presence." https://lnkd.in/dZPjiRS View in LinkedIn

IT ONLY TAKES ONE MUTATION to cause lethal diseases in the worst case. Equally, generic variation can add to fitness. 175 mutations per generation is a game of Russian Roulette. https://lnkd.in/dSzSV3z View in LinkedIn

DUPLICATE EXACTNESS. "From cell division to cell division, the error rate for DNA polymerase combined with other repair enzymes is about 1 mistake in 1 billion base pairs copied. At this rate, there are about 6 mistakes with each diploid cell replication event. With a male/female average of 29 mitotic divisions before the production of the next generation, this works out to be about 175 mutations per generation." https://lnkd.in/dSzSV3z View in LinkedIn
