Humans evolved 5-7 million years ago during the Pliocene. The Mid-Pliocene is the most recent period with atmospheric CO2 comparable with the present (ca. 400 ppmv), with mean annual surface temperatures approximately 1.8 °C to 3.6 °C warmer than preindustrial temperatures.

Modern humans evolved 200K-300K years ago. In the last 650K years, Earth's climate was characterized by large climate swings as the ice ages advanced and receded triggered by changes in Earth's orbit relative to the Sun. Slow changes to the shape of the Earth’s orbit and wobble of the Earth’s axis caused cooling that was amplified by natural effects, including the growing ice sheets and the reduction of carbon dioxide by being absorbed in the oceans. Over tens of thousands of years the amplifying feedback caused the ice ages. The warm climates of the interglacials, the periods between ice ages, were similar to today, but probably a little cooler than right now. A few interglacials were a little bit warmer; some were a little bit cooler.
