The pony phylogeny chart.

Species status:

	O Extant
	X Extinct
	Q Predicted

Pathways:

	| Observed via fossil record
	+ Observed via fossil record
	- Observed via fossil record
	* Predicted

Currently the pony reproduction system is strained due to the large amount of morphological changes that are required in cross-species reproduction. Already, mixed breeds are becoming rare and Earth ponies together with Earth ponies already only beget Earth ponies. With this in mind the prediction is obvious.
