AI Thread Summary
The discussion centers on the feasibility of replacing food with nutrition tablets or injections. While it is technically possible to provide equivalent nutrition through methods like parenteral nutrition, the conversation highlights that practicality and preference play significant roles. The idea of replacing traditional food with alternative nutrition sources raises questions about desirability and the human experience of eating. Astronauts are mentioned as a potential group that might benefit from such alternatives due to their unique circumstances. Overall, while nutritional substitutes exist, the consensus leans towards the importance of food beyond mere nutrition.

Thread 'Did they discover another descendant of homo erectus?'

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...
