The sciencemag.com article “Anti-Alzheimer’s Gene may have Led to the Rise of Grandparents” by Kelli Whitlock Burton talks about the how the protective variant of the CD33 gene may explain why humans have grandmothers that help with child rearing. The article explains the “grandmother hypothesis” that says humans live such long and healthy lives even after they are no longer able to reproduce because they help with child rearing. The CD33 gene plays a big role in Alzheimer’s disease and scientists Ajit Varki and Pascal Gagneux discovered that there are two variants of it: a protective allele and a damaging one.…
Bruce Bowers article, “Fossils hint at India’s crucial role in primate evolution” published in September of 2016, gives the theory of how certain bones excavated from a coal mine in India resemble the first primates from as early as 65 million years ago (). This article states how these bones approximately reveal how a common ancestor would look like and act. Researchers believe that since having the qualities of both superfamilies, Adapoidea and Omomyoidea they left behind a large quantity of different skeletal traits. With the idea that the evolution of primates and their relatives occurred on an isolated island of idea then spread, that gives them the time to evolve and have the specific bone structure and abilities that key them into being…
1. From birth to 19 years of age, children and young people tend to follow a broad developmental plan. Although children and young people are different, the way they grow and develop is often quite similar. This means we can work out a pattern for development and from this we can pinpoint particular skills or milestones that most children can do at different age ranges. Milestones describe when particular skills are achieved, such as walking, usually achieved by 18 months. These milestones have been draw up by researchers looking at children’s development and working out an average from their recordings. However as children grow older the variations between individuals grow larger.…

The animal that most resembles us is the ape. At the zoo, it is easy to observe behavioral and facial expressions in monkeys and apes that are very much similar to our own. A group of apes could very well seem like a family. A mother taking care of her young may seem familiar to the human onlooker. This is because the ape is our closest living relative. In the documentary Primate Behavior, anthropologists observe the behavior of monkeys and primates. The primates are mostly observed in the wild, as they are better understood while placed in a natural setting. This is where the social structure of the primate can really be interpreted.…
Although all children will develop at different rates and in different ways, the sequence in which they develop will be roughly the same as they need to have developed one skill, for example walking, before they move on to develop another skill such as running and jumping.…
Primates are one of the most interesting mammals on earth, not only because of their complex social structures, but because they hold so many similar characteristics to humans. Primates are often cited as our closest living relatives and on two separate occasions I observed four separate species of primates at the San Diego Zoo that can justify their use of their physical characteristics and behaviors that may be similar as well as different to the other primates and ours.…
Arms and hands are more developed than feet and legs (cephalocaudal development) hands appear large in proportion to other body parts.…
Physical developments of a child are associated with the motor skills and physical growth of the child. As a child grows, and his or her nervous system becomes more mature, the child becomes more capable of performing increasingly complex actions such as walking, running, balance, and coordination which involve the larger muscles like arms and legs, as well as, some more intricate skills such as drawing, writing, grasping…
During a child's first year of life they will begin to practice holding and manipulating small objects. Doing this develops the child's ability to use their small muscles…
They can climb with increasing confidence, Catch a gently thrown ball, run and walk backwards. They gains control over eating tools.…
According to the textbook, physical disparities are the product of physiological and maturational differences. In addition, children are impacted by socialization. For example boys are given more freedom than girls. This teaches boys to be independent this has direct impact on activity level. In conclusion, “boys get more practice using their motor skills…laying the groundwork for increased strength later”. My nephew’s motor skills have developed over the years because he has had exposure to sports.…
Children need to master a lot of different types of movements as they grow and these can be broken down into three further categories which consist of gross motor movements or otherwise known as large movements, for example being able to control head, arms and legs. Secondly, locomotive movements or otherwise known as moving and balancing for example being able to walk, jump and move around…
| At this stage, children will be able to carry out more co-ordinated movements and will be growing in confidence They will be refining the skills developed so far and will have more control over fine motor skills…
Children between these ages are more confident with movement and have developed a higher motor and physical skill within the activities, that take place in a school ( Writing, Cutting, Drawing) and home environment (Running, Playing sports- Kicking, Throwing)…
