  Wormholes can be described as geometrical structures in space and time that
can serve as connection between distant regions of the universe.
Mathematically, general wormholes can be defined both on stationary as well as
on dynamic line elements. However, general relativistic and evolving Lorentzian
wormholes are less studied than their static wormhole counterpart. Accordingly,
in this work we shall focus on some evolving wormhole geometries. Starting from
a general class of spherically symmetric line element supporting wormhole
geometries, we shall use the Einstein's field equations to develop viable
astatic wormhole solutions. We will also discuss various evolving wormhole
solutions together with their physical significance, properties and throat
energy conditions. We claim that the method discussed in this work shall be
applicable for developing wormhole solutions corresponding to any general
Lorentzian wormhole metric.
