How does Edward Albee use imagery in Seascape?

Much of the play's imagery can be seen in its symbolism. The beach-where land and sea meet-represents a place of progress. In the theory of evolution, creatures emerged from the sea to live on land like Leslie and Sarah do in the course of the play. Changes for all four characters are taking place at the beach. Another symbol is the jet planes that zoom overhead. The jets are another symbol of progress, but a more mixed one than those already discussed. The Jets are described to Sarah as the mechanical evolution of the seagulls that fascinate her. Yet Charlie worries that a jet will one day crash into the dune-a temporary if not symbolic end to evolution. The Jets also scare both Sarah and Leslie But the jets continue to fly and never crash, and the lizards decide to embrace their evolution. Though feared by everyone but Nancy In Seascape, change seems endorsed by the play's complex symbolism.
