Heritable Variation in a Population Variation within the realm of natural selection is the cornerstone of a healthy population with the ability to adapt to a given environment. Indeed, the reality is that natural selection and evolution are sciences of variation and inheritance.

Variations known as heritable variations are those which are passed on from one generation of a population to the next. It is important for these variations to remain intact between generations because certain elements within a given organism may have made a positive change which allows the creature to live more comfortably in its environment. As these positive changes are passed down through...

This is the basis for evolution.
In human beings, research shows that populations which developed in warm climates tend to be taller while populations which developed in cool climates tend to be shorter. This makes sense as the taller body provides more surface area allowing body heat to dissipate more readily. The shorter body in the cool climate also makes sense. A smaller person has less body to warm than a taller person. Each of these characteristics were developed over many generations through variations which allowed for positive adaptations in the given environment. Those…

(Joseph, 2001; Tehrani and Mednick, 2000) in these studies, it was found that there were strong correlations between children of criminals and antisocial behavior. There were internal variations within studies. One study showed that adopted children of white collar criminals were more likely to be criminals than those of violent criminals. One of the reasons why firm determinations cannot be made as whether nature (genes) or nurture (environment) triumphs

Aggression from a Heritability Perspective There is a social bias against the idea of aggression, so that many people conflate the ideas of aggression and violence, so that they cannot separate them. This suggests that aggression is negative, which is not necessarily the case. The result has been that suggestions that aggression is somehow genetic have been morphed into the notion that people carrying those genes must somehow be inferior

Genetic Risk Factors for Cardiovascular Disease Family History of Cardiovascular Disease The term cardiovascular disease (CVD) is frequently used interchangeably with 'heart disease', but for some medical professionals, the term CVD is used to describe only those medical conditions that lead to the narrowing or blocking of blood vessels (Mayo Clinic Staff, 2012). For others, the term CVD encompasses a number of medical conditions affecting the health of all aspects of the

living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant kingdom (ex, plants take in carbon dioxide and prepare their own food), these characteristics are commonly observed among all living things. Biology is a very broad field that encompasses the study of characteristics of living things. It includes

Mindful vs. traditional martial arts toward improved academic grades in children diagnosed with ADHD While medication and psychotherapy are the current best practice in treating attention deficit hyperactivity disorder (ADHD), their benefits and aim are too peripheral and topical -- neither resolving the neurological origin of deficits. Moreover, many are opposed to these treatments and there are few substantiated and readily accepted alternatives. The consequences of ADHD have a ripple effect --

3 million buildings and plots of land. If it can conservatively be assumed that a minimum of five persons are affected for each business and a minimum of two persons for each building, then some 5 million people are directly involved in property-restitution claims - nearly a third of the population of the new Lander. (Blacksell et al., 1996, p. 200) Since December 1991, the number of claims filed with the
