The cells of all animals—including humans—are characterized by their ability to adhere particularly well to surfaces in their environment. This mechanically stable adhesion enables the development of complex tissues and organs and is made possible by certain cell surface receptors called integrins. However, it is unclear how this form of cell adhesion developed over the course of evolution, as many single-celled organisms do not have integrin receptors.
