We have reconstructed the three-dimensional density fluctuation maps to z ~1.5 using the distribution of galaxies observed in the VVDS-Deep survey. We usethis overdensity field to measure the evolution of the probability distributionfunction and its lower-order moments over the redshift interval 0.7<z<1.5. Weapply a self-consistent reconstruction scheme which includes a completenon-linear description of galaxy biasing and which has been throughly tested onrealistic mock samples. We find that the variance and skewness of the galaxydistribution evolve over this redshift interval in a way that is remarkablyconsistent with predictions of first- and second-order perturbation theory.This finding confirms the standard gravitational instability paradigm overnearly 9 Gyrs of cosmic time and demonstrates the importance of accounting forthe non-linear component of galaxy biasing to consistently reproduce thehigher-order moments of the galaxy distribution and their evolution.
