In the same sense that all cows in a herd or sheep in a flock or drops in the ocean are essentially the same, so are all juveniles in the human herd essentially the same. Same in essence. All juveniles are, for all practical purposes, identical. There is no notable difference between any two herdmates. Different spots, maybe, so they can tell each other apart, but that’s where the dissimilarity ends.
