What I know is that birds go into the deva evolutionary stream. Fish, being more primitive must be precursors to both streams. Reptiles evolved into birds, but does that mean they exclusively go the deva way? Not sure.

The monad evolves through many intermediary stages in its evolution. The goat, with a shared goat mental body, will transition to a higher mammal. Whether it is a dog or a horse I do not know. What matters is that it has now got its own individual share of what was originally a shared goat mental body. At this stage, it is not under the protection of a solar angel, that happens later when the higher mammal causalises. This happens when a solar angel adopts that monad.

Apes are a different kettle of fish. We did not from them, they came from us! This is referred in the Secret Doctrine as the ‘sins of the mindless’, a fascinating story in itself.

As monads evolve, they are always just a single monad. You can not have missions of goats sharing a monad. Each goat is a monad that has now reached a stage where it has its own etheric and emotional body. The mental body is still shared with all the other goats. There are still devic forces, which themselves are monads that will be managing all these goat monads in their collective envelope. How this level of deva hierarchy is organised I do not know. However, the goat needs to first gain an individual mental body before it is ready to be adopted by a solar angel. This is when casualisation takes place and the monad begins a long process of developing its own self-identity while remembering its past incarnations. This is not done consciously at first, but when the 3rd initiation is complete, the monad knows what it has experienced in its totality. In the Human Kingdom, the monad is responsible for its own actions. The goat is not, as its mental activity is shared and is also at a very low level.
