  Density linear perturbations in Einstein-Cartan two fluid cosmologies where
the outer model is an isotropic Friedmann solution with closed model while the
inner model is a flat anisotropic Einstein-Cartan (EC) cosmology with shear are
computed by taking into consideration superhorizon situations.This situation is
in agreement with the present isotropy of the Cosmic Background Radiation where
the anisotropic EC model evolves into an isotropic general relativistic
model.Galaxy formation is discussed based on this model.Another type of two
fluid is considered where the inner solution is a pressureless Kasner type
solution while the outer solution is a de Sitter solution with spin and
torsion.
