Cells become attached, and a multicellular organism results.
Hiroki Oda

    The attachment of cells to each other, known as cellular adhesion, is a mechanism that arose more than one billion years ago when multicellular organisms emerged from unicellular organisms. Multicellular organisms began to be created in complex forms that separated themselves from the outside due to an alteration in the mechanism for cellular adhesion. When the cells of multicellular organisms began not merely to adhere, but to separate, move out of alignment, and combine, the creation of a single form began to occur from a single fertilized egg for the first time. There are different types of cellular adhesion. The example we will examine here is the lining of the small intestine of vertebrates.

    Of these, only the adherence junction related to form and movement exists in most bilaterally symmetrical animals, ranging from sea urchins and insects to vertebrae.
If there are few deaths of the prey due to predation, does the existence of predators have no relationship to ecological stability?
