multicellularity

There are various mechanisms by which multicellularity could have evolved.

So long as reproduction simply means one cell copying itself, true multicellularity cannot exist.

The evolution of multicellularity has required the suppression of cancer.

Multicellularity would have been a priority development and collagen one of its certain prerequisites.

The development of entirely new ammo acids was the real key to opening the way for complex multicellularity.

The mere act of clinging together, as in seaweeds, involves no true multicellularity, however.

This suggests that the evolutionary leap to multicellularity may be a surprisingly small hurdle.

This was the first organism that exhibited sexual reproduction, which is an essential feature for complex multicellularity.

King has been a pioneer in identifying choanoflagellates as key organisms to answer questions about the origin of multicellularity.

We know, from their cell structure, that multicellularity has evolved independently many times in Earth history, for example in plants and animals.

The advance from unicellularity to multicellularity must have begun when cells divided and then remained clinging together.

Therefore, sexual reproduction and the ability of gametes to develop into an organism is the necessary antecedent to true multicellularity.

True multicellularity requires the establishment of a "cellular society" with needs that overbalance those of the individual cell.

The closest that the excavates come to multicellularity are the Acrasidae slime molds.

Sexual reproduction eliminates such rogue cells from the next generation and therefore appears to be a prerequisite for complex multicellularity.

Dictyosteliida contains organisms that hover on the borderline between uni- and multicellularity.

King continues her studies on choanoflagellates and multicellularity as an associate professor at the University of California, Berkeley.

Multicellularity makes possible specialization.

Complex multicellularity is different from "simple" multicellularity, such as colonies of organisms living together.

"Plants have evolved their multicellularity completely separately from animals, and any direct comparisons between the groups are wrong," Dr. Raven said.

Coprinopsis cinerea became important model organism to study multicellularity of fungi and in 2010 its genome had been sequenced.

The evolution of multicellularity could have occurred in three ways, and of which the latter, the colonial theory, is most credited by the scientific community:

This type of motility is an example of an emerging concept in microbiology : bacterial multicellularity.

Multicellularity exists in both prokaryotes and eukaryotes, and first appeared several billion years ago in cyanobacteria.

One exciting target is a newly characterized signal transduction pathway that communicates cell population, enabling individual bacteria to act with multicellularity.
