Through years of excavations and careful analysis of her finds around Krasnyi Yar in Kazakhstan, archaeologist Sandra Olsen has assembled what may be evidence of the earliest known people to have domesticated and ridden horses, a momentous development in human history.

Topic

Possible evidence for early horse domestication and riding among the Botai people in Kazakhstan.

Framework

Answer / Explain

Main Point

Archaeologist Sandra Olsen uses several lines of evidence—mainly patterns in horse bone remains—to argue that the Botai people of Kazakhstan likely domesticated and rode horses around 6,000 years ago, rather than simply hunting them for meat. (The most valuable sentence appears near the end of P1: )

P1: The Puzzle of the Botai Horse Remains

Olsen investigates vast horse bone deposits from the ancient Botai people, noting that horse bones don’t show clear signs of domestication like other animals. She focuses on patterns in the age and sex of the remains to figure out whether these horses were wild or domesticated.

P2: Analyzing the Bone Patterns—Wild or Domesticated?

Olsen explains typical herd management (culling young males) versus hunting patterns. The Botai horses don’t fully match either model: there are many fully grown males, suggesting a different relationship. Olsen suggests that if the Botai were riding horses, they would have kept adult males alive for that purpose.

P3: Skeletal Clues and Special Treatment

Finding whole horse skeletons (not just parts you'd expect from a hunted animal) and evidence of intentional burial alongside human remains further supports the idea that the Botai weren’t just hunting horses, but had a special, possibly domesticated, relationship with them—potentially even riding them.

10.

If the horse remains found at the Botai sites had consisted primarily of the bones of fully grown females and young males, the findings would have provided evidence for which one of the following hypotheses?

  1. The Botai targeted male pods

    Opposite: pods vs. families

    If they hunted male pods, then we'd find a lot of adult male bones. In this question, they're finding adult females and young males, which suggests that the Botai were hunting families of horses, not bachelor pods.

  2. The Botai caught, trained, and

    Unrelated to Goal Opposite, if anything

    This doesn't sound like either of our predictions. - hunting horse families - domesticating horses for meat/milk It's also kind of an oxymoron to say that a horse that is caught and trained is a "wild" horse. That sounds pretty domesticated. The horses most often ridden were adult males, so it seems like a mismatch for "mainly adult female and young male".

  3. Correct

    The Botai had domesticated horses

    Why this is right

    Since these horses weren't adult males, they probably weren't being ridden. Since their whole skeletons were still intact, they probably weren't wild horses who were killed and butchered for transport. So that leaves the idea of domesticated (which fits the profile of not seeing many adult males) and not ridden (which fits the profile of not seeing many adult males).

  4. The Botai had developed sources

    Trap

    Opposite, if anything Out of Scope: other food sources Our leading hypothesis was that "adult females and young males, with fully intact skeletons" means that these were horses that herders had domesticated for meat and milk. In other words, the horses were a source of food. This answer is saying it suggests the opposite?

    5% picked this

  5. The Botai incorporated the remains

    Out of Scope: cultural rituals

    We have no connection from "adult female and young male" to "incorporated into cultural rituals". If anything, we'd expect that a horse that is ridden and bonded with would be involved in cultural rituals, but that type of horse would most likely be adult male.
