Gelatinized pleistocene collagen

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1973
Abstract 1. 1. Treatment of Pleistocene bones from Rancho La Brea with hot water has solubilized most of their collagenous protein. 2. 2. The resulting mixture of polypeptides when hydrolyzed with strong HCl has yielded amino acids in the relative proportions characteristic of pure gelatin and collagen. 3. 3.

Pleistocene and pre-Pleistocene Begonia speciation in Africa

Molecular Phylogenetics and Evolution, 2004
This paper presents a historical biogeographic analysis of African Begonia based on combined internal transcribed spacer (ITS) and trnL intron sequences. Age range estimates for Begonia in Africa ranged from only 1.5 Ma for some terminal nodes to 27 Ma for basal nodes when the ages of Réunion (2 Ma) andMayotte (5.4 Ma) were used to date the split ...

Early Pleistocene

2007
This chapter introduces the beginning of Pleistocene vertebrate records, starting from an overview of the latest Pliocene events and the Plio-Pleistocene transition. Understanding the early Pleistocene vertebrate record is impossible without the knowledge of the events characterizing the setting of early Pleistocene land vertebrate communities.
