However, according to a 2019 study published in Nature, crocodiles have the "full range of quadrupedal footfall patterns used by mammals," which means they can gallop like a horse—and occasionally do! Of course, they aren't as graceful, but they can reach speeds of up to 11 miles per hour.

Scholars think that Pachacuti Inca Yupanqui, who governed the Inca Empire from 1438 to 1471, began constructing Machu Picchu around 1450 AD. This is almost a millennium after the fall of the Roman Empire and less than a century before the arrival of the Spanish conquistadors in Peru.

The researchers behind this project compiled data from museums, botanical gardens, agricultural centers, and other sources to conclude that there are currently 60,065 tree species known to science. These include Abarema abbottii, a rare and poorly understood tree native to China and Kyrgyzstan, and Zygophyllum kaschgaricum, a vulnerable limestone-bound tree found only in the Dominican Republic. The Global Tree Assessment, which aims to assess the conservation status of all of the world's tree species by 2020, is the next step in this field of research.
