Human Organ Evolution

Executive Summary

The paper discuss about the historical aspect of human organ evolution. The pattern of the early growth is often known as a significant factor for later health, both in short term survival and later for the risk factors of chronic disease of afflunece. Thus, the differential pattern for the organ growth, are particularly prenatal, that were not considered in studies. The study for human growth conventionally focuses on the entire body, notably the volumetric and linear measures of weight and height, including the derived ration body mass index. The knowledge regarding the human organ development and fatal growth has developed greatly in the past 50 years. Physiologists and Anatomists had described it already with some crucial aspects that are being described in this assignment.

Human Organ Evolution

Introduction

Recently it has been observed that the systematic have actually developed well. As various new contributions and methods from the diversity in the biological fields have been analyzed that includes the developmental and genetics biology that provides the wealth for Phylogenetic hypotheses, as some contradicting and other confirming the traditional over views. However, with such inconsistencies, still it is possible for recognizing the robust regions for “tree of life” and it also identify the problematic area that needs to be resolved. It is a fact that organs does not appear all of a sudden during evolution, instead they are actually composed of far more simpler structures. In various cases it is even possible for tracing particular physiological or molecules pathways being far back as the pre-animal history (Singer, 2008).

The evolution can be based on the idea that says that the entire organ is being developed from simpler ones, however, once the original organ is evolved, an improved and new organ is subsequently evolved from it. For a structure or organ to be selected by natural selection, it needs to be first exit. It is a fact that a particular organ might be larger or even more complex in one human than in other, but it does not necessarily means it is more evolved. Our body is also a machine and, as such, it needs fuel to work and develop their activities: running, jumping, walking, playing, thinking and all that can keep their organ active.

Aims and objective

The aim of this term paper for describing the process for normal organ growth in the fetus, child and embryo, which hsows how this relates to the growht in the whole organism.

Discussion And Analysis

The Origin of Life The evolutionary principle must be understood as a process of universal application. By all indications we have at present, unable to rule for the unity of origin and source of terrestrial living beings, because there is an absolute homology biochemical constitutional order. The emergence of the first living matter must be preceded by a 'chemical evolution', which would occur as abiotic organic molecules. The energy needed for life would be given by the heat, cosmic rays and ultraviolet rays (O'Rahilly, ...
