A comparison of observed and simulated isolated galaxies allows us to check their evolution in a wide range of redshifts and to reveal and evaluate a possible impact of their environment. Using the Minimal Spanning Tree (MST) technique we select samples of isolated galaxies, in the SDSS DR7 and in the moderate resolution dark matter simulation. We find that the separation to the nearest neighbour should be 4-5 h-1 Mpc to produce a sample of isolated objects with substantially peculiar environment.
