  In this work we study the effects of introducing long range interactions in
the Bak-Sneppen (BS) model of biological evolution. We analyze a recebtly
propopsed version of the BS model where the interactions decay as r^{-alpha};
in this way the first nearest neighbors model is recovered in the limit alpha
-> infinity, and the random neighbors version for alpha=0. We study the space
and time correlations and analize how the critical behavior of the system
changes with the parameter alpha. We also study the sensibility to initial
conditions of the model using the spreading of damage technique. We found that
the system displays several distinct critical regimes as alpha is varied from
alpha=0 to alpha -> infinity.
