Bacteria were isolated from internal tissues of surface sterilized healthy tubers of Solanum tuberosum cv. Maris Piper (8 different isolates) and from tubers inoculated with Erwinia carotovora ssp. carotovora showing soft-rot symptoms (3 different is...

On the evolution of multicellularity and eusociality (1999)
Journal Article
Bull, L. (1999). On the evolution of multicellularity and eusociality. Artificial Life, 5(1), 1-15. https://doi.org/10.1162/106454699568656

In this article versions of the abstract NKC model are used to examine the conditions under which two significant evolutionary phenomena - multicellularity and eusociality - are likely to occur and why. First, comparisons in evolutionary performance... Read More about On the evolution of multicellularity and eusociality.
