No it was not, horse evolution was found to be more complicated than previously thought. Rather than a simple stright lineage leading directly to the modern horse
Equus, it is a brancing pattern leading in multiple directions over time. Think of a tree or bush rather than a ladder.

The "Creation Ministry" and "Creation sciecne" sources you have been using are LYING to you.

Don't take my word for it, investigate yourself. Look at science websites and sources, not just creationist ones. Look critically at what you are being told. This is a good website to begin:
