Reptiles with longer Wikipedia pages tend to be bigger. The relationship is a power law with exponent = 0.85. I guess humans really like writing about big lizards? The longest article is the Komodo Dragon.

Great to see this news! With Ugandan fisheries personnel, I sampled rivers all around the Ugandan flank of Mt Elgon almost 20 years ago when there were no large wild mammals remaining. At the time this absence and the development that caused it seemed irreversible.

For the first time since the 1970s, elephants have returned to the Ugandan side of Mount Elgon. The Uganda Wildlife Authority calls it a major win for forest restoration efforts, while rangers work closely with local districts to protect crops and manage human-wildlife conflict.

OTD in 1912, Alfred Wegener delivered a lecture propounding the theory that our modern continents were formed by the splitting and drifting apart of an ancient supercontinent, which he named Pangea. Due to his failure to offer a plausible mechanism, he was widely ridiculed. 🧠🗃️⚒️ 🧪 #HistSTM #PhilSci
