More on gene regulation:
Organisms can even change sexes by making use of gene regulation. Here is an interesting article from the NYT showing sex changes in fish are common:
http://www.nytimes.com/1984/12/04/sc...nd-common.html
"WHEN a school of reef fish loses its single male, the largest female begins acting like a male within a few hours and will produce sperm within 10 days. Some other species repeatedly switch back and forth between the production of eggs and of sperm during a single mating. Among deep sea fish that only rarely encounter potential mates, reproduction is often possible only if one changes sex.
Such opportunistic sex changes in fish, once thought to be a rare oddity, are proving far more common than supposed. Conversions from female to male are now known to occur in species belonging to at least 14 families, while conversions from male to female are known in eight families." |
Still the same animal coward
No new never before seen family of animals magically sprout into existence in this example either. No new, never before seen genetic code is magically being written spontaneously by random chance.
