Evidence for pattern development (Introduction)

I've been discussing patterns of life in the organ systems that have to be developed to have complex advanced life emerge. Convergence, the phenomenon of similar organs or structures with similar function in different species, supports this idea of patterns of development:-"The team's results demonstrate that the evolution of overall gene expression underlying convergent complex traits may be predictable. This finding is unexpected and could indicate unusually strong constraints: The probability of complex organs evolving multiple times with similar trajectories should be vanishingly small, noted Oakley. Yet the team's novel bioinformatic approaches indicate the evolution of convergent phenotypes is associated with the convergent expression of thousands of genes."-Smells of pre-programming, doesn't it?-http://www.sciencedaily.com/releases/2014/10/141021135020.htm-This also belongs in Natures wonders, because of the symbiosis of bioluminesent bacteria in the employ of the squid:-"They chose to work with the Hawaiian bobtail squid (Euprymna scolopes) and the swordtip squid (Uroteuthis edulis), a Japanese species used for sushi. These distantly related species are two of five genera known to have bioluminescent organs called photophores. The photophores contain symbiotic, light-emitting bacteria, and the squid are capable of controlling the aperture of their organ to modulate how much light is produced."
