Antonio Garcia-Bellido is a developmental biologist who specialises in researching the genetics of animal development. He is specifically interested in how genes control growth, or morphogenesis, in insects. Antonio discovered that groups of genes can act together to define a developmental operation, in a similar way to a computer chip.
Working in the fruit fly, Antonio was the first to map the progression of embryonic tissues to adult tissues, a process known as fate mapping. He discovered that cell populations in the developing tissues of insects are restricted to specific compartments of their cell type. This led him to develop the theory that as development is modular, the genes behind it must be working together.
