The evolution of the horse family, from small fruit-eating animals with four front and three back toes to the majestic, long-legged, single-toed modern grazing horses beloved by racing enthusiasts, is a remarkable testament to the power of natural selection. However, like rhinos and tapirs, the horse-like zebras, wild asses, kulans, kiangs, onagers, and real horses are often portrayed as having reached their evolutionary peak compared to the more recently evolved ruminants, particularly bovids and deer, which now dominate the grazing niche. This narrative of a species group's peak is captivating, but anyone who has ventured into the remote savannas of Africa or the cold wild deserts of Central Asia will be awe-struck by the sight of magnificent herds of animals that clearly do not ruminate. It seems as though these so-called "hind-gut fermenters" are better adapted to these environments than one might assume.

The purpose of this book is to dispel the myth of the inferior Equidae by presenting a comprehensive account of the evolutionary and ecological journey of the horse family in all its splendor. We will explore the various stages of their development, from their early ancestors, which were dog-sized fruit-eating animals with four front and three back toes, to the modern horses we know today. We will also examine the ecological factors that have influenced their evolution, such as habitat changes, climate fluctuations, and competition with other species.

Throughout this journey, we will discover the remarkable adaptations that horses have developed over millions of years, allowing them to thrive in a wide range of environments. From their strong, flexible bodies to their specialized digestive systems, horses have evolved to be efficient grazers and predators. We will also explore the role that horses have played in human history, from their use as transportation and warfare to their current role as companions and sports animals.

In conclusion, the evolution of the horse family is a fascinating story that highlights the incredible resilience and adaptability of nature. By examining the evolutionary and ecological journey of the horse family, we can gain a deeper appreciation for the complexity and beauty of the natural world and the role that animals play in shaping our world.
