Introduction:
For the origin of multicellularity, the cells need to communicate with each other. The protein domain called cadherins function in cell signaling. On comparing the genome of animal cells and choanoflagellates, it was found that both contain similar protein domains.
The eukaryotes are believed to have evolved from protists as shown by the morphological and genetic studies. Protists are closely related to plants, fungi and animals as compared to other protists.
