The initial developmental process that will lead to the formation of an eye. Establishment of the optic placode, a thickened area of densely packed ectoderm cells directly overlying the optic vesicle in the early embryo. In Drosophila, for example, the placode appears in the dorsolateral region of the head in late stage 11 embryos and is the precursor to the larval visual system. The process whose specific outcome is the progression of the optic placode over time, from its formation to the mature structure. During embryonic stage 12 the placode starts to invaginate, forming a pouch. Cells that will form Bolwig's organ segregate from the ventral lip of this pouch, remaining in the head epidermis. The remainder of the invagination loses contact with the outer surface and becomes the optic lobe. An example of this process is found in Drosophila melanogaster. The process by which anatomical structures are generated and organized during the embryonic phase. Morphogenesis pertains to the creation of form. The embryonic phase begins with zygote formation. The end of the embryonic phase is organism-specific. For example, it would be at birth for mammals, larval hatching for insects and seed dormancy in plants. The biological process whose specific outcome is the progression of an anatomical structure from an initial condition to its mature state. This process begins with the formation of the structure and ends with the mature structure, whatever form that may be including its natural destruction. An anatomical structure is any biological entity that occupies space and is distinguished from its surroundings. Anatomical structures can be macroscopic such as a carpel, or microscopic such as an acrosome. The developmental process by which an ectodermal placode forms. An ectodermal placode is a thickening of the ectoderm that is the primordium of many structures derived from the ectoderm.
