organisms, especially where a fully developed central nervous system and brain is
found, there is strong indication of centralized control of many aspects of the animals behavior.

To explain how his hypothetical code - script might work — it had to be extremely complicated because it involved «all the future development of the
organism» — Schrödinger resorted to some
simple mathematics to show how the variety of different molecules
found in an
organism could be encoded.
But while this study has proved that the technique works in a
simple organism, it could also be applied to other bacterial species, yeast or even human cells to
find useful information about how genes are controlled and how they can be manipulated.
This is one of the first times that scientists have
found simple, genetically similar
organisms that communicate across long distances — yeast and slime mold, in contrast, require direct contact.
The reason for the disparity may be that the standard computer annotation method was largely developed for the genomes of
simple (prokaryotic)
organisms, not for the more complex sequences
found in the genomes of humans and other eukaryotes.

found only in multicellular
organisms, and not more
simple one - celled life forms.
As one of the three initial cores established when the Buck Institute was
founded, the Genomics Core has played a vital role in helping shape investigations in the basic molecular biology of aging, from assisting in the investigation of how specific drugs can extend lifespan in
simple model
organisms such as the nematode C. elegans, to facilitating studies in various animal models of age - related disease.
As different as these cells and
organisms may appear on the surface, genetic elements from even the smallest and
simplest organisms can also be
found in humans.
I doubt you will
find any complex
organisms (probably
simple as well) with exponential growth and I don't see why trees shouldn't be included in that characterisation.
