Anthropology

Ancient Megalithic Structure Older Than The Egyptian Pyramids Discovered In The Peruvian Andes. “Dated to around 2,750 B.C., using radiocarbon dating techniques, the circular stone plaza was built using massive vertical stones placed in upright positions. This construction method is similar to other ancient sites from the ancient world, like Stonehenge, which is approximately the same age as the newly discovered stone plaza. However, the researchers say it is a construction style “previously unseen” in the Andes.”

Astronomy

Life on Mars could have thrived near active volcanoes and an ancient mile-deep lake. “…crustal changes behind these newly discovered volcanic features are analogous to a step that Earth took on its own evolutionary pathway toward plate tectonics more than 2.5 billion years ago.”

For those who don’t know – “Euglenids are a group of unicellular eukaryotes that gain energy through both photosynthesis, like a plant, and through consuming other beings, like an animal.” This seems like the sort of article one should review in celebrations of Darwin’s birthday today.
Life on Earth may have first sparked in shallow “soda lakes.” “The emergence of life requires high phosphate concentrations, far exceeding those found in natural water bodies like rivers, lakes, or oceans.”
