Descripción del proyecto
La cinemática de los primates informa a los modelos computacionales para comprender mejor nuestra evolución
La carga mecánica que soporta los huesos afecta a la remodelación ósea. La contracción de los músculos, el impacto al caminar o el empuje de las fuerzas gravitatorias modulan la compleja interacción entre la formación y la reabsorción ósea. Un ejemplo sencillo de este proceso es la pérdida ósea a corto plazo experimentada por los astronautas en un entorno de microgravedad y que puede ser compensada en parte con un ejercicio físico riguroso mientras están en el espacio. A muy largo plazo, es decir, a escala evolutiva, la remodelación ósea ayudó a nuestros antepasados humanos a adoptar nuevas posturas y movimientos como, por ejemplo, la locomoción bípeda. Si bien es necesario comprender cómo se relaciona la forma con la función para entender mejor nuestra historia evolutiva, aún quedan muchas preguntas sin resolver. DeMol combina estudios cinemáticos en primates con métodos comparativos computacionales y filogenéticos avanzados para cerrar esta brecha en el conocimiento.
Objetivo
The challenge of better knowing the complex relationship between bone's morphology and function has yielded tens of articles since the beginning of the last century and is essential for making positional behavioural inferences on fossil taxa. Despite its relevance, the form-function relationship is still poorly understood. Based on this premise, this project focuses on deciphering the functional loading environment and its influence on skeletal design in the hindlimb of living primates and shedding light on the locomotor evolution of fossil apes and early hominins. The fossil apes included in this project constitute key taxa for understanding the positional behaviour evolution within the Hominoidea (the apes and humans clade), which has important implications for a better knowledge of the evolutionary pathway that led to the specialized locomotor types of extant apes and humans (specialized antipronograde behaviours such as below-branch suspension and human terrestrial bipedalism). To accomplish the aims, this project will rely on diverse, multidisciplinary and innovative techniques, including biomechanical and engineering approaches (e.g. multibody dynamics analysis, computer optimization, machine learning and data science), phylogenetic comparative methods, and collection of experimental data (e.g. recording of live primates kinematics). This project also involves an important component of training for the applicant and several short stays to gain a diversified and unique set of skills and knowledge on the field of paleoprimatology and evolutionary biology. Hence, this project will extend our knowledge on the bone's form-function relationship, as well as the origin, tempo and mode of the hominoids positional behaviour evolution, including key long-lasting questions related to the origins of human bipedalism.
