Unlike its predecessors, Homo erectus was bipedal, that is, they were the first humans in the evolution line to walk in two legs with an upright posture (Science & Technology). They had the biggest brains, in proportion to their body sizes, as compared to their predecessors. They also had longer legs and sorter arms. This was because they had reduced their adaptation towards tree climbing. They also had a larger variation in heights as compared to other ...

Dwarfism is defined as a physical disorder that is characterized by short stature and inability of a person to achieve a minimum height of 148 cm in his or her adulthood. Dwarfism has several types and various etiologies. The reasons of it might be genetic, metabolic or constitutional. Nowadays there are approximately 100 kinds of dwarfism, however none of these kinds is common because dwarfism occurs only in 0.5 to 1.5 births per 10000. In general there are two main qualifications of dwarfism. The first qualification relates to patients with short stature but proportionate and normal trunk-to-limb ratio. The ...

Formation of bone during foetal development occurs through the process of ossification. This process is extremely important to proper bone length, density, and uniform skeletal formation. It is driven by a complex network of genes that code for signalling proteins whose function is to turn the ossification process on, off, or slow it down. Defects in these genes can cause problems with the ossification process, and can lead to conditions of skeletal dysplasia (improper formation of bone). One such condition is Achondroplasia, one of the most common forms of dwarfism, or congenital short stature (Lister Hill National Centre for Biomedical ...
