up to you to learn basic science which you demonstrably have not....what's your agenda BTW?
You don't really expect anyone to take you seriously?? That's almost as ridiculous as your position

You dont need to patronising. Im a scientist myself and quite frankly Mr Lenskis experiments and results which have been heralded as a success and a scientific breakthrough is an absolute joke.

One of the colonies of bacteria learnt to live on citrate.....WOW!!!! Big deal!!!

Despite having generation times of only 20-30 minutes and subjecting the bacteria to all sorts of various chemicals, biologicals, mutagenic and environmental factors....did the unicellular bacteria form a multicellular organism of just two cells and this over a period equivalent of tens of millions of human years??

Phagotrophy by a flagellate selects for colonial prey: A possible origin of multicellularity

Abstract

Predation was a powerful selective force promoting increased morphological complexity in a unicellular prey held in constant environmental conditions. The green alga, Chlorella vulgaris, is a well-studied eukaryote, which has retained its normal unicellular form in cultures in our laboratories for thousands of generations. For the experiments reported here, steady-state unicellular C. vulgaris continuous cultures were inoculated with the predator Ochromonas vallescia, a phagotrophic flagellated protist (‘flagellate’). Within less than 100 generations of the prey, a multicellular Chlorella growth form became dominant in the culture (subsequently repeated in other cultures). The prey Chlorella first formed globose clusters of tens to hundreds of cells. After about 10–20 generations in the presence of the phagotroph, eight-celled colonies predominated. These colonies retained the eight-celled form indefinitely in continuous culture and when plated onto agar. These self-replicating, stable colonies were virtually immune to predation by the flagellate, but small enough that each Chlorella cell was exposed directly to the nutrient medium.
