Article Synopsis
- The Sima de los Huesos site, discovered in 1976 and excavated systematically since 1984, is dated between 430,000 and 300,000 years ago and has yielded over 7,000 human fossils, the largest find before Homo sapiens.
- The fossils represent at least 29 individuals of varied ages and sexes, and studies suggest a close relationship to Homo neanderthalensis.
- Key findings include insights into body size, evidence of intentional burial, care for disabled individuals, and indications of complex oral communication similar to modern humans.
A taxonomic study of diatoms was carried out in a tropical coastal lagoon. Material for this study consists of water samples obtained from February-March 1992 to November-December 2000. Qualitative and quantitative analyses showed the presence of 373 taxa of which the families Bacillariaceae (67 species) and Chaetocerotaceae (37 species) were the most abundant groups.
