Here we present new stable carbon isotope data from the late Pliocene mammalian fauna from Ledi-Geraru, in the lower Awash Valley (LAV), Ethiopia, and mammalian community analyses from the LAV and Turkana Basin. These data, combined with pedogenic carbonate stable isotopes, indicate that the two regions were largely similar through the Plio−Pleistocene, but that important environmental differences existed during the emergence of&amp;nbsp;&lt;/span&gt;&lt;i style=&quot;color: rgb(34, 34, 34); font-family: Lora, Palatino, Times, &#039;Times New Roman&#039;, serif; font-size: 17px; letter-spacing: 0.17000000178813934px;&quot;&gt;Homo&lt;/i&gt;&lt;span style=&quot;color: rgb(34, 34, 34); font-family: Lora, Palatino, Times, &#039;Times New Roman&#039;, serif; font-size: 17px; letter-spacing: 0.17000000178813934px;&quot;&gt;around&lt;/span&gt;&lt;span style=&quot;color: rgb(34, 34, 34); font-family: Lora, Palatino, Times, &#039;Times New Roman&#039;, serif; font-size: 17px; letter-spacing: 0.17000000178813934px;&quot;&gt; 2.8 million years ago.
