The evolution of multicellularity enabled specialization of cells, but required novel signalling mechanisms for regulating cell differentiation. Early multicellular organisms are mostly extinct ...

Solving the puzzle of multicellularity Piecing together the mystery of how single cell life forms evolved into multicellular organisms Date: February 2, 2018 Source: University of the ...

Multicellularity could have been achieved numerous times based on the premise that selection acts on phenotypes and how well certain combinations of traits work. In other words, even if cells ...

Frankly, I am distressed by the amount of subjectivity in human society, and I seek to avoid that in science. I grant, though, that biologists must be fascinated by the evolution of multicellularity, ...

Origins of multicellularity: All in the family Date: July 9, 2010 Source: Salk Institute Summary: One of the most pivotal steps in evolution -- the transition from unicellular to multicellular ...

Multicellularity does not have to manifest this way, however. Just a hop, skip, and a jump over from us on the tree of life are the choanoflagellates —little marine and freshwater creatures ...

Foreword : the evolution of multicellularity / John Tyler Bonner -- I. Functional and molecular predispositions to multicellularity. Fossils, feeding, and the evolution of complex multicellularity / ...

Scientists don’t completely understand how this kind of multicellularity evolved in animals. Cell-to-cell adhesion, or the ability for individual cells to stick to each other, certainly plays a role, ...

In the first genomic analysis of a multicellular brown alga, researchers see an increase in membrane-spanning receptor kinases, relative to their unicellular diatom relatives. The kinases are a ...

Sulfur dictates cell function and multicellularity It turned out that the loss of sulfur was the important process underlying this multicellularity, and that increasing ROS was a clever means for D.
