Evolution of primate intelligence
Words • 2025
Pages • 9
There has been significant effort to elucidate the evolutionary history of the hominoid species over the last five decades. Several approaches have identified a number of selective pressures that have triggered primate speciation over approximately 65 million years (my). One traditional approach is macroevolution, which explains phylogeny through comparative anatomy, fossil records, brain size, gestation period, social organization and mating patterns. Another type of approach is microevolution, which describes molecular changes through time, including genome size, chromosomal rearrangements, gene reorganization…...

Charles Darwin gave his theory of evolution by the way or Natural Selection in 1858 as an explanation for adaptation and variation in species and organisms. Natural selection is the differentiation of organisms due to the differences in phenotype. Natural selection acts on the phenotype of an organism. The phenotype is the observable characteristics of a specific organism resulting from the interaction of its genotype with the environment. The phenotype is determined by an organism’s genotype, which is its genetic…...

Survival Of The Fittest Philosophy

Pages • 15
In the current essay we will review the survival of the fitters, different issues and theories connected with it. Survival of the Fittest – is the aphorism, introduced by Herbert Spencer and Darwin said in “Origin of Species” (1859) as the main factor of the theory of natural selection. This theory states: (A) reproduction in any species implies a certain degree of natural variations in results; (B) Any change that increases the survival ability of some members of the species…...

This paper gives an explanation of Darwin’s theory of natural selection. As well, the paper fully gives a description of natural selection in terms of “modern evolutionary synthesis” of the 20th century. The paper also gives application of the principles of natural selection to explain the current problem of antibiotics resistance in bacteria. Finally the paper gives a summary of scientific theories about evolution before Darwin’s discovery of natural selection.Generally this is a very important theory which has been greatly…...

Geneticist is currently working on the human genomes to identify difference genes that are available for selection between the Africans, the Asians and the European. Buoyed by the recent evolution evidence in China and Tibet, the article explains that populations living in Africa where life is believed to have been seeded have fewer genes up for selections than their European and Asian counterparts. The explanation is that those who moved away from Africa might have acquired new genes as they…...

The mechanisms for individuals in a population to survive heterogeneous habitats have been a strong debate within the scientific community. The native European Littorina obtusata are a great model organism to study Darwin’s Theory of Evolution by Natural Selection. This is because of their vast phenotypic characteristics, particularly their evolving shell thickness throughout history due to predatory pressures of the new arrival of Carcinus maenas. Here we test whether L obtusata three most critical tenants of Darwin’s theory of evolution…...

Changing Species, Changing Environments: Unit Project The way organisms evolve is a very delicate process, and a number of factors can influence this. A prime example would be the recent evolution of the wild Soay sheep residing on the Scottish island of Hirta. First of all, this changing environment is producing variations to this species in ways that evolutionists would not expect. In addition, the impact of these changes is widespread throughout this population, and will lead to many differences…...

Studies in the field of behavioral and reproductive biology have proved that courtship is of great importance in the population of guppy (Poecilia reticulate). In this courtship male guppies are known to attract females by displaying their body. Females are known to attract to males with large body contour, much colorful fins and with greater courtship display. In the time of courtship, male guppy expands its fins and repeatedly moves its body from back of head to tail end in…...

In the poem “A Blessing,” James Wright analyzes the relationship between human beings and nature through the descriptive explanation of an encounter between his friend and himself and two Indian horses. He shows that although we are able to relate and interact with the animals we don't have the ability to join them or as Wright puts it: “break into blossom” (26-27). Wright uses imagery and personification to describe the nature he witnesses as he escapes from the stress of…...

Natural Selection through Competition and Isolation of Species
Words • 517
Pages • 3
The struggle for life results in differences in form which Darwin called “incipient species. ” Darwin says that variations, no matter how small or big they are, will necessarily be passed down to offsprings because they will tend to make those individuals survive. He called this process natural selection to relate it to man's ability to select objects in their lives. Herbert Spencer, an English philosopher, had previously described the struggle for life as the “survival of the fittest,” which…...

Several studies have been carried out particularly on polygenic traits that have different alternate forms for example, white flower color vs. purple flower color. However many traits are more multifaceted than this and can take on any number of incessant values. For instance in humans there are not just two groups of people i.e. tall vs. short- but a full range of possible heights. To add on, many traits are not controlled by a single pair of gene but by…...

In this article written by Jared Diamond entitled “Race Without Color”, he explains about the difference of race in humanity and how humans should not be classified that way because there are too many variations. Depending on how a person looks, they would be put into a certain race categories such as “African blacks,” “whites,” “Mongoloids,” “aboriginal Australians”, and “Khoisans.” However, this classification of humans only affect how we view others; it does not involve our senses or who we…...

Natural selection, according to Gulick, is the process through which heritable attributes that are beneficial or vital for survival and reproduction become a common thing in a population, whereas harmful characteristics become rare (p, 27). Natural selection occurs as a result of successful reproduction by persons who have advantageous traits (Darwin p, 39). This results in adoption of beneficial traits by the subsequent generation. Over a number of generations, adaptations take place through successful combination of small, random alterations in…...

In 1831, he joined a five year scientific expedition on the survey ship HMS Beagle. This is where he came up with his theory of evolution. During his voyage on the Beagle, Darwin found evidence that challenged traditional belief that species are unchanging.…...

Compare Darwin’s Theory of Evolution to Lamarck’s

There have been many theories explaining evolution. Two of the most well known of these are the Lamarckian theory, which was mostly believed before the Darwinian theory, which is the theory which is believed to have the highest probability of it being the case. In Lamarck's theory of evolution, he stated that an organism was able to pass on required traits to their offspring. This theory is commonly shown through the giraffe's evolution to having longer legs and a longer…...

The history of evolutionary psychology began with Charles Darwin, who proposed that humans have social instincts that evolved by natural selection. Darwin's work inspired later psychologists such as William James and Sigmund Freud but for most of the 20th century psychologists focused more on behaviorism and proximate explanations for human behavior. As school psychology transitions into an outcome-oriented profession, we continue to evolve new ways to bring science into applied practice in schools. This evolution is critical to the continued…...

Naturalism in Jack Londons “To Build a Fire”
Words • 2002

Even with our ability to tame some sides of nature, there are still certain conditions and forces which are beyond control; we inevitably are left with no will, powerless against nature’s indifferent influence. This struggle against nature is depicted by many authors of the 19th and early 20th centuries, using key concepts of naturalism and determinism, a key component of naturalist theory, as a foundation and philosophy for many of these stories. Jack London and Stephen Crane are notorious for…...
