Resumen
Los primeros humanos consumieron geofitas almidonadas, como Hypoxis, hace al menos 170.000 años. La evidencia arqueológica de Border Cave, Sudáfrica, revela el uso de estos rizomas de plantas ricas en carbohidratos.
Área de la Ciencia:
- Paleoantropología
- Arqueobotánica
- La prehistoria de África
Sus antecedentes:
- Los carbohidratos vegetales se consumieron en la antigüedad, pero las geofitas con almidón rara vez se conservan arqueológicamente.
- La comprensión de las primeras dietas humanas requiere la identificación de restos de plantas preservadas.

Fungal Group Zygomycota
905
Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

Sugars as Energy Storage Molecules
9.7K
Sugar (a simple carbohydrate) metabolism (chemical reactions) is a classic example of the many cellular processes that use and produce energy. Living things consume sugar as a major energy source because sugar molecules have considerable energy stored within their bonds. Consumed carbohydrates have their origins in photosynthesizing organisms like plants. During photosynthesis, plants use the energy of sunlight to convert carbon dioxide gas into sugar molecules, like glucose. Because this...
