If an animal (or human) eats only C3 plants, their δ<sup>13</sup>C values will be from −18.5 to −22.0‰ in their bone <a href="/wiki/Collagen" title="Collagen">collagen</a> and −14.5‰ in the <a href="/wiki/Hydroxylapatite" class="mw-redirect" title="Hydroxylapatite">hydroxylapatite</a> of their teeth and bones.<sup id="cite_ref-C-Tycot_32-0" class="reference"><a href="#cite_note-C-Tycot-32"><span class="cite-bracket">&#91;</span>16<span class="cite-bracket">&#93;</span></a></sup> </p><p>In contrast, C4 feeders will have bone collagen with a value of −7.5‰ and hydroxylapatite value of −0.5‰. </p><p>In actual case studies, millet and maize eaters can easily be distinguished from rice and wheat eaters. Studying how these dietary preferences are distributed geographically through time can illuminate migration paths of people and dispersal paths of different agricultural crops. However, human groups have often mixed C3 and C4 plants (northern Chinese historically subsisted on wheat and millet), or mixed plant and animal groups together (for example, southeastern Chinese subsisting on rice and fish).<sup id="cite_ref-C-Richard_33-0" class="reference"><a href="#cite_note-C-Richard-33"><span class="cite-bracket">&#91;</span>17<span
