Only a few ways to evolve! > > http://www.sciencedaily.com/releases/2012/10/121025130922.htm-And now we find that a special lipid helps hearing in dolphins, whales and insects!-"We don't know why animals who are so far apart in evolutionary terms have this similarity, but it opens up the possibility that others may use the same system component." The sound is known to be transmitted through a liquid-filled cavity to reach the hearing organs, but until the current research was carried out it was presumed that the liquid was simply the insect equivalent of blood. The researchers found that it was in fact a lipid of a new chemical class. They believe the role of the lipid is to efficiently transmit sound between compartments of the ear, and perhaps to help amplify quiet sounds."-http://www.sciencedaily.com/releases/2012/12/121213084939.htm

Convergence is everywhere. Here is insects. One researcher says evolution is predictable:-"The finding of parallel evolution in not two, but numerous herbivorous insects increases the significance of the study because such frequent parallelism is extremely unlikely to have happened simply by chance," said Zhang, who is familiar with the study but had no role in it."-The biochemistry is so limited chance cannot be operative!-"The power of what we've done is to survey diverse organisms facing a similar problem and find striking evidence for a limited number of possible solutions," he said. "The fact that many of these solutions are used over and over again by completely unrelated species suggests that the evolutionary path is repeatable and predictable." -Only a few ways to evolve!-http://www.sciencedaily.com/releases/2012/10/121025130922.htm

An amoeba which has a nucleus. Wow!-http://the-scientist.com/2012/07/03/opinion-one-microbes-15-minutes/-The Darwin 'tree' get bushier and bushier. Convergence? You bet!-http://the-scientist.com/2012/07/03/opinion-one-microbes-15-minutes/

Convergence is the parallel development of living organs or tissues in various species. The eye in human and octopus is the prime example. It is now shown that muscles in jelly fish and similar species are not the same as our muscles, another evidence of convergence. Convergence demonstrates that life is very inventive and the Darwin step-by-step tree of development is not correct. Darwim could not have known this more recent information. Therefore the tree of life has to be adapted to a bush form more like a field of bush-like weeds sprouting up in many directions.-http://www.sciencedaily.com/releases/2012/06/120628145626.htm-I interpret this as evidence of intentionality in evolution
