Left unfettered, the trend of ever-larger size would produce organisms of gargantuan proportions.

The non Vibrio but hydrogen sulphide producing organisms produce a black small colonies.

These genetic engineering techniques, employed to create vaccines and antitoxins, sometimes produce new organisms about which little is known.

Neurons create thought and consciousness, other cells work together and communicate to produce multicellular organisms.

This gas is produced by some gas producing micro organisms which infect most upper parts of urinary system.

As selection and drift act independently on populations isolated from the rest of their species, separation may eventually produce organisms that cannot interbreed.

After a few thousand generations, the simulation produced organisms that were able to predict their "mealtimes" based on temporally linked environmental cues.

Why hasn't evolution produced organisms that practically last for selecting for is reproductive success.

For the same reason, big business is now busy producing and releasing genetically modified organisms, fish etc. into the environment.

If the "tape of life", to recall the expression of Stephen Jay Gould, were run again, it would not produce dramatically different organisms each time.
