sample of k particles without replacement from a population alive at large time
in a critical Galton Watson process in varying environment.  Our
approach uses k distinguished spine particles and a suitable change
of measure similar to a k-size biasing with a discounting rate
proportional to the total population size. Under this measure, we
provide the law of the splitting times of the spines and the offspring
distribution of particles on and off the spines.</span></p>
