Together, the results suggest that the adaptations are able to maximize oxygen delivery to cells and tissues without thickening the blood – a result that would place more stress on the heart as it struggles to pump a higher viscosity fluid more resistant to flow.'</p><p>( And some aspect of the adaptations could have been inherited from Denisovans)</p><p><a href="https://www.sciencealert.com/humans-are-evolving-right-in-front-of-our-eyes-on-the-tibetan-plateau" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">sciencealert.com/humans-are-ev</span><span class="invisible">olving-right-in-front-of-our-eyes-on-the-tibetan-plateau</span></a></p>
