    One of the most remarkable examples of self-organized structure formation is the development of a
    complex organism from a single fertilized egg. With the identification of many molecules that
    participate in this process, attention has now turned to capturing the physical principles that govern
    the emergence of biological form. Living systems are special in the sense that they structure
    themselves through processes that convert chemical energy into mechanical work. In this talk I will
    provide a brief introduction into 'Active Matter Physics’, and discuss how the surface of a cell can
    generate active stresses that can drive its reshaping, or the reshaping of many cells that are
    collectively organized into a tissue. I will end with a report of our efforts of combining active matter
    theory with experiments in both worms and birds to understand symmetry breaking and pattern
    formation in early organismal development of active living systems.
