Includes live video seminars, enchanting renewal songs and a thousand page illustrated codex. A transformative network reflowering Earth's living diversity in gender reunion. Experiments suggest that this kind of reproduction has different advantages for an organism, depending on how challenging its environment becomes.
Sex is expensive.
Besides expending energy in the generation and use of the necessary organs, sex permits an individual to pass on only half of its genetic material to its offspring. Theoretically, evolution should favour asexual organisms that pass on their entire genetic complement. There are two main theories about why such a costly strategy would evolve. One says that sex creates more variability in each generation and so improves a species' chances of survival in an ever-changing environment. The other suggests that sex maintains the overall fitness of a species by clearing out harmful mutations-the least healthy offspring die, taking the damaged DNA with them.
