Other studies suggest that TRPM, along with TRPA and TRPC, has evolved later in the unikont lineage, as it is present in the genomes of the choanoflagellates Monosiga brevicollis and Salpingosea rosetta, representing the last unicellular ancestor of Metazoa (Mederos y Schnitzler et al.
Role of TRP Channels in Dinoflagellate Mechanotransduction
In the new vision--based on increasingly sophisticated genetic analyses--people and other animals are closer cousins to single-celled choanoflagellates than to other multicellular organisms.
Strange relations: schoolroom kingdoms are taking a backseat to life's supergroups
Recently, integrins and other components of the integrin-mediated adhesion and signalling machinery have been identified in unicellular organisms; such as in the filasterean Capsaspora owczarzaki, a close relative of metazoans and choanoflagellates.
Spain-Unravelling the function of integrins in the unicellular relatives of Metazoa Project
By this means it was revealed that all the flagella and cilia in animals including sponges, Mesozoa and choanoflagellates showed the twoheaded outer arm profile.
Tubulin-dynein system in flagellar and ciliary movement
Choanoflagellates are one-celled eukaryotes that are the closest relatives of animals (Figure 2).
Visualizing proteins & their evolution
Free-living, unicellular organisms called choanoflagellates, however, could be on every person's family tree, so long as it was a gigantic one.

Symmetrical letter patterns
These data support the view that all animals are derived from choanoflagellates, but cannot differentiate between single or multiple origins of multicellularity.
The developmental role of the extracellular matrix suggests a monophyletic origin of the kingdom Animalia
However, [alpha] and [beta] integrin subunits were subsequently identified in the protist Capsaspora owczarzaki, revealing an ancient origin for these receptors predating the appearance of animals and their selective loss in choanoflagellates (Sebe-Pedros et al.
Integrins of the starlet sea anemone Nematostella vectensis
In that scenario, colonies of single-celled organisms called choanoflagellates gave way to multicellular predecessors of sponges; millions of years later, an offshoot of these organisms formed nerve cells.
Comb jelly genes redraw tree of life: DNA data show creature belongs to earliest animal lineage
A study of choanoflagellates, which are unicellular protists that resemble the collar cells of sponges, suggests that they also have both these important tools.
From the beginning
One of the best studied groups of heterotrophic flagellates is the choanoflagellates.
