In George Orwell's Animal Farm, what is significant about how the animals arrange themselves as they gather to hear Major?

The animals
group themselves by species, the dogs together, the pigs together, the hens and pigeons
together, suggesting from the start that the idea that "all animals are equal" will
have to overcome some obstacles based on "class." The dogs and the pigs sit near each
other and near the front, showing their connected and dominant positions in the hierarchy.and
Clover are characterized from the start as caring, as they worry that they will step on some
small animal they don't see in the straw. The sheep and the cows lie behind the pigs, showing
that they will follow the pigs' lead later on. Moses, the raven, stays outside. He represents
the clergy, the voice that pacifies the animals and upholds the current status quo by telling
them stories of a wonderful afterlife, and like the real clergy in Russia, will not take part in
the revolution/rebellion.

The dogs' instinctively going after the rats does
not bode well. The animals, to successfully implement their ideals of Animalism, will need to
overcome many natural tendencies and will need good leadership to do this.can provide that
leadership, though he dies before the Rebellion, but it is equally possible for a more cynical
leader to exploit the natural tendencies of the animals, such as the dogs, for his own gain,
which is whatwill do.
