Triune Creator Purposeful Creation

According to Darwin and his theory on evolution, organisms are presented with nature’s challenge of environmental change. Those that possess the characteristics of adapting to such challenges are successful in leaving their genes behind and ensuring that their lineage will continue. It is natural selection, where nature can perform tiny to mass sporadic experiments on its organisms, and the results can be interesting from extinction to significant changes within a species.

This Fleeting World is a small summary of ‘big history’. David Christian’s book is a mere 92 pages long with an included 9-page prequel (on topics during the first years without humans such as Earth’s creation and more) and 16-page appendix on the book’s use in school, historical periodization, and a 4-page list of sources. With around 120 pages, this short book seems to be the perfect size to represent how our species’ history is only miniscule fraction compared to the history of that around us. In a world that has been around for over four and a half billion years old (6) in a universe that is 13.8 billion years old (1), homo sapiens have been around for only approximately 250,000 of those years (9). It seems impossible, though, to fit those hundreds of thousands of years into the modest text. However, Christian does the impossible and makes a well written short ‘big history’. Where many other historians before him have failed at making one, Christian’s book, This Fleeting World, summarizes history from the big-bang all

At its core, this theory supports the notion that only the strongest organisms survive in a changing environment while their weak counterparts die off. Nevertheless, various circles regard the evolutionary theory by natural selection as practically impossible. Since its conception, proponents of the theory have defended it with the help of

Since the Earth’s birth, this is about 4.6 billions years ago animals have faced massive obstacles in sustaining life due to unforgiving environmental conditions. As a result, only few animals have survived while the other 99.9% have became extinct (Deep Time 2001). The mechanism that allowed the 0.1% to outlive the unfortunate is evolution. In a broader picture, it can be described as a change in a population’s appearance over generations. More specifically, evolution it is a change in the genetic makeup of a population over time that is a consequence of mutations, crossing over, or independent assortment. Moreover, this change brings about a positive impact in the population as seen in Finches, which evolved to have stronger beaks in response to harder foods (Yoon 2007). The spread of stronger beaked finches was a product of natural selection; a process by which better-adapted animals survive to produce offspring, while other animals lacking certain advantages will not

In Naturalistic Evolutionary view point, Earth was formed out of nothing 4.6 billion years ago, and went through several different periods of intense transition to arrive at what we now see. The first period of transition is known as the Precambrian in which “the most important events

This signifies the year of publication of Charles Darwin’s novel On the Origin of Species by Means of Natural Selection. After 20 years of intensive research and studies, Darwin finally published his findings in this controversial theory. His hypothesis that the world revolved around natural selection intrigued many. The purpose of this study/lab was to understand the process of natural selection posed by Charles Darwin through a simulation involving competition of various preys and predators. It is important to study this because it can expand the knowledge of natural selection and show how survivorship can influence evolution amidst individuals in a population. By focusing on phenotypic selection, we can understand why some live longer than others, or why some species have gone extinct. Environmental factors, biological and non-biological—such as predators, parasites, and weather directly affect natural selection (Kingsolver and Pfennig, 2007). As climate change continues to increase annually, the urgency of comprehending how living things adjust to these new ecological settings is becoming vital. Botero et al. (2014) studied coping mechanisms of organisms under changing environmental conditions and discovered a successful method—phenotypic plasticity, the ability to modify genotypic express either during early development or throughout life in response to environmental cues.

Earth as known today is just temporally. The planet is always changing and once it was far different than it is now, it was an extreme habitat when life first appeared. The first fossil confirming life existence dates from 3.5 billion years ago [8]. However, the characteristics of this fossil indicate it was an organism reasonably evolved, suggesting that life appeared much prior in time. Even at present days is still hard to determine when the first life form appeared on Earth, since rocks older than approximately 3.5 Ga have been

Evolutionary thought and research has come a long way in the last few decades. While several factors have been identified as contributing to species evolution (Huxley 1942), natural selection is widely accepted as the main and strongest evolutionary force. However, Gould and Lewontin (1979: 581-598) argue there is a danger in trying to explain all evolution using an adaptationist programme where selection is the go to answer, even to the exclusion of other possibilities

Life on Earth is made up of a diverse array of plants, animals and microorganisms. The slow, diverse process of evolution results in such diversity. Natural selection is a process that drives evolution by selecting for traits that allow an organism to adapt and survive (and thereby reproduce) in its environment. Though adaptations help an organism survive in its environment, every adaptation either results in the loss of some other trait or reduces the performance of the other trait(s) (Freeman, 2013). Adaptation as a result of evolution by natural selection may result in anatomical alterations and/or changes in behavior (Schussler, 2014).

Evolution by natural selection, proposed by Charles Darwin in 1859, requires a population to have three necessities. These include variation, which leads to differences in fitness, and a form of heredity for this variation (Bourrat 2014). Natural selection acts solely by accumulating slight, successive, and favorable variations and cannot produce great or sudden modifications because it can act only by very short and slow steps (Darwin 1859). Nevertheless, there are always numerous potential selective pressures in nature that limit a population’s evolution and fitness like predation.

Precambrian time is most of the Earth's history, starting with the planet's creation about 4.6 billion years ago. There are many theories on how life began. Some people say there was a “Big Bang” that happened 4.6 billion years ago. Scientist say that some chemicals collided with some solar energy and then there was a big explosion that created the world we live in today. No one can prove that the

Evolution is the gradual development of life on Earth. It is responsible for the unusual carnivorous plants (species such as Dionaea muscipula), the beautiful coloured plume of the male peacock, even the possibility of cells adapting to protect against continual low exposure to radiation (Russo, GL. et al 2012). Without it, the lavish diversity of organic life we interact with every day would be non-existent.

One of the most important shifts in evolutionary biology in the past 50 years is an increased recognition of sluggish evolution and failures to adapt, which seem paradoxical in view of abundant genetic variation and many instances of rapid local adapta- tion. I review hypotheses of evolutionary constraint (or restraint), and suggest that although constraints on individual characters or character complexes may often reside in the structure or paucity of genetic variation, organism-wide stasis, as described by paleontologists, might better be explained by a hypothesis of ephemeral divergence, according to which the spatial or temporal divergence of populations is often short-lived because of interbreeding with nondivergent populations. Among

Evolution depends on both inheritance and selection (Arnold, 1994). Heritable traits having some advantage to an organism must be passed on from one generation to the next. As a result, the organisms that have inherited these traits will be better suited for survival in a specific environment. In other words, the ability for an individual to survive is not enough to fuel evolutionary progression- there must be reproduction taking place as well (Figure 1).

Modern humans have been on Earth for more than 200,000 years. Although many people feel that 200,000 years is a fairly long time for us to have existed as a species, it is quite the opposite. The earth is estimated to have been made 4.54 billion years ago. Life as we know it is estimated to have begun 4 billion years ago. When comparing the existence of the human race to the existence of the planet we live on or the existence of all forms of life, it becomes very apparent that the humans species time on this planet has been relatively miniscule. If you took the entire history of the 13.7 billion year old universe and compressed it into one year, the first humans would not even show up until 10:30 pm on December 31st.
