A Good Explanation Of The Evolution Of Human Behavior

The concept of evolutionary psychology can be thought to have originated from sociobiology. Wilson (1975) suggested that socio-biology was the most important factor in the process of starting to relate evolution to behaviour. Sociobiology is a theory that stems back to the 1970’s and can be defined as the study of the genetic origin of social behavior. Sociobiologists concentrate on how behavior patterns might be “built in” or genetically influenced. However Social behavior stems from evolutionary process. Thus this field of research suggests that several methods of social interaction have resulted from evolution. This was concluded when Darwin (1859) pointed out that the theory of evolution brought about

One of the most astonishing things on earth is the human body. They consist of many organs that work together to maintain the person alive. The humans body composition is complex, but what was the origin? How did we become who we are today? These are the questions that intrigued me, and allowed me to understand how the human body evolved over the years. By the examination of our ancestors, and our body we will understand how we look today.

Around the 1950’s a new discipline began to emerge, ethology, which focused on animal behavior in its natural environment. Niko Tinbergen, one ethology’s founding fathers, distinguished four questions to ask when a specific behavior is performed. “What was the internal physiological cause of the behavior?” (Stevenson et al., 2013, p. 267) the behavior occurred due to an internal change. For example, if the behavior occurred due to hormone secretion or a muscle contraction. “What in the development or experience of the individual prepared the way for that behavior?” (Stevenson et al., 2013, p. 268) if a complication occurred in the development of the fetus in the womb it could prevent sexual maturity, ultimately creating an excuse for abnormal behavior. “What is the function of the behavior” (Stevenson et al., 2013, p. 268) the individual is behaving this particular way in order to achieve some sort of goal. “What is the evolutionary history of this pattern of behavior” (Stevenson et al., 2013, p. 268) by examining ancestral behavior patterns we can distinguish their intentions or adaptations. These four questions pertaining to behavior can be applied to almost all species, including humans, both male and

In D.T. Max’s essay on “How Humans Are Shaping Our Own Evolution”, he states that we are,” taking matters into our own hands.” After saying this, he quickly starts to mention both the effects (both positive and negative) of both naturally occurring adaptations and the artificially occurring adaptations that often occur through the ever-advancing means of technology.

The behavioural theory states that personality is as a result of the interaction between an individual and the environment (i.e. the society and the individual). It is focus on observable and measurable behaviour rather than mental or emotional behaviours and different theories focus on one type of behaviour over the other. On the contrary, the biological approach seeks to explain behaviour as a result of interactions within the body. It is based on assumptions such as how the brain psychology can influence behaviour and also how behaviour can be inherited

Particularly, the chapter fifty-four lecture which focused on behavioral biology. Here we first discussed biological genetics and the differences of nature and nurture. Nature relating to the genetically similarities while nurture is more environmental causes for behaviors. The chapter also discusses territorial behaviors as exemplified in the article. For instance, humans become more violent with societal pressures or threats to their territory. On the other hand, we have the idea of phylogenetic species (shared characteristics among populations) as discussed in chapter twenty-three lecture. Concluding that comparative biology is also demonstrated in this

Edward Wilson argues that biology is the key to understanding human nature. He explains how, as products of evolution, we are simply physical beings and a study of our biology will reveal everything about human nature. Wilson then provides a number of examples of how our biology affects us. For example, he explains how altruism, a trait that seems unintuitive for natural selection, could arise through natural selection by the trait passing through relatives that benefit from the altruism. His argument in standard form is:

In regards to, evolutionary psychologists’ usage of natural selection to comprehend human’s behaviors along with, the thought process can and will be an ongoing study due to the fact, that people change with the time era. Furthermore, one’s surrounding has a lot to do with the actions as well as, the behavior patterns (Meyers, 2005-2014, p. 69).

This essay will outline and compare both biological and behavioural perspectives on human behaviour. The history, major discoveries and theories will be discussed along with some of the most influential theorists in each of these two areas of psychology. This essay will also compare the two areas strengths and weaknesses in the field of psychology.

The bio-psycho-social model is an adequate approach to understanding behavior because it looks at the mechanism, motive and context behind a person’s behavior. The Bio and Psycho aspects of this model explain the internal stimuli behind a person behavior while the Social shows how outside facts affect it as well. It can be argued that this model is not adequate because it leaves out how environmental aspects play into a person’s behavior, but this factor doesn’t play the same role in behavior as the other three.

The origin of modern human behavior is a subject in anthropology that accumulates much debate. Cognition is the dominant factor in such behavior, therefore raises the question, “when did this separation of intelligent or modern thought from the primitive come to daily behavior for our genus?” There are two such answers that hold experts in the field captive in debate: the rapid “imagination revolution” in the European-centrailized Upper Paleolithic, and the steadiness of cognitive growth provided first in Africa during the Middle Paleolithic. Although each argument provides supportive evidence for their perspective claims, the more naturally convincing shows this creative revolution taking place much earlier than the Upper Paleolithic. This explanations human cognition developing with no brisk advantageous revolutionary response, and instead by gradual means. This metamorphosis follows the pattern of biological human evolution. My argument combats the “imagination revolution” claim to the origins of creativity using specific artifacts dated earlier than those of European restrictions. Furthermore, it is the lack of excavation in Africa and the conditions of the terrain itself that pose problematic preservation of artifacts, unlike in Europe, to exonerate this innovative exclusivity. These pieces of evidence in Africa exemplify a higher process of thinking, commonly those showing deliberate means of bead and rock art used for both personal functions of expression. If art

Humans have existed on Earth for approximately 3.4 million years. The oldest known human ancestor is "Lucy," an Australopithecus. Over this extensive period of time, humans have evolved significantly. Homo Sapiens have grown from 3 to almost 6 feet (average), lost most of the body hair, became leaner and adapted to walking. Humans have come a long way, from Australopithecus to Homo sapiens, from living in trees to living in cities. Slowly, through hundreds of thousands of years, we mutated over and over again, natural selection ensuring that no destructive mutations continue. From the slow evolution, four distinctive species emerged and died out, each giving way to its ' descendant: Homo Habilis, Homo Erectus, Homo Sapiens Neanderthalesis, and Homo sapiens Sapiens.

Human life histories are understood to consist of different levels of factors that contribute to the variation and evolution of human health, and this can be analyzed by categorizing the various lifetime events on a fast-slow continuum (Promislow & Harvey, 1990 as cited in Kaplan, Lancaster, & Robson, 2003). Mammals, for example, are located on the fast end of the continuum and are known to reproduce early, have a shorter period of pregnancy, grow into smaller body sizes, and produce a great amount of offspring that are vulnerable to death. On the other hand, species scattered on the other end of the continuum tend to have characteristic that are opposite to those of mammals (Kaplan et al., 2003). These changing momentums are generally

Homo Sapiens as the species to which all modern human beings belong and is the only one from genus Homo that is not extinct.

Human evolution according to research started over 6 million years ago. The outcome of the evolution process is the current human beings. Scientific studies have revealed over the years a remarkable affinity between the chimpanzees/Apes and human beings. Even though this reality is not a definitive prove that human beings evolved from apes, it does show that the human beings are in one way or another related to other primates. Scientists suppose that the humans and the primates shared a common ancestor. The subject of what makes humans what they are and their origin has been the exclusive purpose leading to many scientific studies globally (Coolidge & Wynn, 2011). Studies believe that Africa was the origin of evolution millions of years ago. Fossil remains have been discovered in different parts of Africa as well as other regions of the world. Different hominins have been discovered around the world in the last 1 million years. Thus, the different discoveries have led to comparisons between the various species of hominins to clarify on their similarities as well as differences. This essay seeks to explain whether they were distinctively different species or regional versions of the same species.
