Sexual selection

Biological anthropology is the study of behavioural and biological aspects of humans, primates and the extinct hominid species (Stanford et al, 2013). Anthropological perspectives and approaches may be applied to research comparisons, and obtain in depth information on comparative anatomy, biocultral and evolutionary changes over time. This essay will address these different approaches. Paleoanthropological findings will also be used as evidence to support the theory of microevolution and…

change to help them adapt to the environment around them, increasing their chances of survival. Natural selection means that the organisms that adapt better survive longer and produce more offspring. The offspring carry on these adaptations, gradually changing the species over time. Darwin’s theory says that all life has descended from a common ancestor. Evolution happens through natural selection. Although some people believe evolution is not real, there is evidence in fossils,…

Introduction Evolution is the theory of how organisms change over time. Scientist believe evolution is a reliable theory by studying anatomy, biochemicals, fossils, and embryology. When studying these they notice the structural similarities. Through these studies scientist can conclude that each organism shares one common ancestor. The purpose of this lab was to observe the bone anatomy of certain animals to find similarities in them. Also doing this experiment i noticed that some of the…

INTRODUCTION Evolution of Development is best described as a field of Biology that compares the developmental processes of different organisms to determine the ancestral relationship between them, and to discover how developmental processes evolved. Whereas Species Development is the genetic switches that allow different structures to develop in different regions of an embryo, which could also give rise to major morphological differences among species. Everyday new species are being discovered…

In this research paper, I will be using the film “Walkabout” and the book “The King of Trees” to express the embodied consciousness of nature inside of the human. Despite the fact that there is always an invisible boundary between human and nature, we often view ourselves apart from nature. Yet as humans, we sometimes unconsciously adapt with the environment around us, and the sense of adaptation inverts into an interaction with our surrounding (nature). Through this interaction, we will…

The Merriam-Webster dictionary explains evolution as a theory of changes that occur because constant change that excel naturally over a long period of time. (Merriam-Webster) This means that over a long period of time there were changes made from all the species and as time progressed we all started to break up into different categories and then different branches of those categories. It is said that we, as humans, share the same category as the primates. Though, over time we started to evolve…

What is race? First of all, “race” like many words varies in its meanings. References to “race” occurs frequently in our everyday life, as we talk about “the human race”. Other reference s are used in our government offices with regards to forms, this purpose is generally used to determine the number of races for the Census. Still other meanings of the term “race” are more technical, for example a biologist talks about different races of a particular species. Because the meanings…

Life will change over time, gradually forming the most adaptable species look. Ancient creatures can be verified by residual fossils: the older the older, the more the difference between its morphology and the existing species. At the same time people can also discover the relationship between species and species from fossils. Archaeopteryx has sharp teeth, feet three toes have claws, long bone tail, these are dinosaur features, and it also has feathers, wings, and modern birds similar, so is…

Acheta domesticus (house cricket) is an ideal specimen for studying nutrition since they are omnivorous and live for about 120 days at 30°C (Lyn et al., 2011). Like other species, crickets compete for resources such as territory, mates, and food. The fighting success of the individual depends on their resource holding power (RPH) and motivation to fight (Nosil, 2002). Predation differs for each individual in forms of affective aggression with regard to motivation and behaviors of the species…

different variations. A common feature of such concepts is the interpretation of the essence of man primarily from the standpoint of biology. Thus, Darwinists believe that the main engine of social development is the struggle for existence and natural selection. Even though, German anthropologist Gerland in On the Extinction of Primitive Peoples in 1868 evaluated Darwin’s theory and came up with critical view about superiority of white race as superhuman when he stated that “Europeans destroyed…
