New Middle Pleistocene hominin cranium from Gruta da Aroeira (Portugal).
The Middle Pleistocene is a crucial time period for studying human evolution in Europe, because it marks the appearance of both fossil hominins ancestral to the later Neandertals and the Acheulean technology. Nevertheless, European sites containing well-dated human remains associated with an Acheulean toolkit remain scarce. The earliest European hominin crania associated with Acheulean handaxes...
متن کاملEarly hominin auditory capacities.
Studies of sensory capacities in past life forms have offered new insights into their adaptations and lifeways. Audition is particularly amenable to study in fossils because it is strongly related to physical properties that can be approached through their skeletal structures. We have studied the anatomy of the outer and middle ear in the early hominin taxa Australopithecus africanus and Parant...
متن کاملFound: The Elusive ANTAR Transcription Antiterminator
Regulated transcription termination provides an efficient and responsive means to control gene expression [1]. Intrinsic terminators, which consist of an RNA stem-loop followed by a poly-U tract, catalyze termination by disrupting the RNA polymerase elongation complex [2]. In antitermination, an antiterminator stem-loop is mutually exclusive with the terminator stem-loop [1,3]. In different con...

متن کاملEvolution of the Early Hominin Hand
The hand is among the most primitive anatomical regions in the human body. The basic fi ve-digit pattern of our manus, including the number of bones in each ray and the retention of many extrinsic and intrinsic muscles (see Chap. 7 ), is likely retained from the ancestral condition for all mammals. While primate hands are generally characterized by two major novelties, namely, nails instead of ...
