Based on their data, Schirrmeister and her doctoral supervisor Homayoun Bagheri believe that there is a link between the emergence of multicellularity and the event. (science20.com)

My first research project was to investigate multicellularity in social amoebae. (improbable.com)

This threshold has been exceeded tens of times, perhaps because much of the requisite molecular machinery to facilitate cell-cell coordination is a shared primitive feature of living organisms, but also because some definitions of multicellularity encompass everything from simple bacterial colonies to badgers.

Multicellularity developed relatively early in the history of cyanobacteria, more than 2.3 billion years ago», Schirrmeister explains in her doctoral thesis, written at the University of Zurich. (science20.com)

The leap from unicellularity to multicellularity is possible only if the originally independent cells collaborate. (sciencedaily.com)
It helps in achieving differentiated multicellularity that all of the cells are identical twins in terms of chromosomal genes (implying a shared control ). (ac.be)

Ray Goldstein, a physicist from the University of Cambridge, put it best as he described his introduction to the field 8 years ago, when a PhD student in biology knocked on his door of his University of Arizona office with a question about fluid mechanics and how this might be impacting multicellularity in Volvox . (the-scientist.com)

We think the symposium was a great success, and it was such a privilege that magnificent talks and thoughts were mixed in a discussion on the conundrums of cancer and multicellularity! (lu.se)

The development of multicellularity has been a remarkable turning point in Earth's biological history, enabling greater morphological diversity and the formation of new organizational structures. (harvard.edu)

These are just some of the questions the visiting scientists at KIPT are trying to answer through a 10-week workshop on cooperation at all levels of life, from the origins of multicellularity to how species and populations interact to form cooperative organizations. (the-scientist.com)

Isolates representative of hyper- multicellularity, no multicellularity, or those expressing only individual phenotypes were injected into Galleria mellonella larvae, a model host for virulence assays, to determine an association with virulence. (wm.edu)

Bradley Olson, from Kansas State University, has been sequencing volvocine genomes-most recently that of the 16-celled colonial alga Gonium pectorale -and has identified candidate genes, such as cell-cycle regulators, that he believes give rise to multicellularity. (the-scientist.com)
According to the scientists, multicellularity developed shortly before the rise in levels of free oxygen in the oceans and in the atmosphere. (science20.com)
