The ongoing scientific investigation of how exactly evolution occurred and continues to occur has been an argumentative idea amongst society since Darwin first articulated it over a century ago. The scientific basis of evolution accounts for happenings that are also essential concerns of religion; both religion and science focus on the origins of humans and of biological diversity. For instance, in the reading “Truth Cannot Contradict Truth,” Pope John Paul II, addressing the Pontifical Academy of Science, discussed the matter of God as creator of man. The Pope explains that men cannot relate to animals because men are superior. The reasoning for that is because God created humans under his likeness. What the church is saying about mankind

Natural selection does not make the species unconditionally perfect. For instance, a rhino with two horns may have a better chance at defending itself than a rhino with one horn. A rhino with one horn may have a better chance at defending itself than a rhino with one horn. Though a rhino with one horn may be in the same environment as a rhino with two horns, they both have the ability to defend themselves if another animal attacks. However, natural selection and evolution is unavoidable. It is something that is always going to happen. As long as the environment can change, a species can change.

A scientific theory is an explanation of an aspect of the world, based on facts that have been frequently confirmed through observation and experiment or is often just speculations. Is evolution just a theory? Evolution is considered a valid scientific theory as it cannot be expressed in a concise mathematical equation so it is referred to as a theory, which does not make it more accurate than a law. Natural selection, comparative embryology, comparative anatomy, DNA and scientific contributions all support the theory of evolution.

Evolution is a change in the genetic makeup of a population over time, with natural selection its major driving mechanism. Darwin’s theory, which is supported by evidence from many scientific disciplines, states that inheritable variations occur in individuals in a population. Due to competition for limited resources, individuals with more favorable variations or phenotypes are more likely to survive and produce more offspring, thus passing traits to future generations. In addition to the process of natural selection, naturally occurring catastrophic and human induced events as well as random environmental changes can result in alteration in the gene pools of populations. Small populations are especially sensitive to these forces. A diverse

This difference is based a gene called prestin. The prestin underwent an adaptive change in both bats and toothed whales. Research shows that amino acid replacements in the evolution of cetaceans have coincided with an increase in the frequency of their vocalizations. This vocalization is associated with an increase in audio sensitivity at higher frequencies. Molecular adaptation occurred at two point. At first, it happened with the split of the ancestral branch of all echolocation toothed whales. The second point happened with the split of the ancestral branch of the group of small toothed whales.

Evolution is the change of traits of a species over several generations. A famous biologist named Charles Darwin, theorized that evolution happens by natural selection. Many people believe that evolution requires millions of years but scientists believe that evolution can occur rather quickly. In Today’s world, we have better health care, food, shelter and hygiene. Some might question if our advanced medicine and technology can lead to a stop in evolution, but in fact we are still evolving according to some scientists (Neild). There has been much debate and controversy over this statement but there is no concrete proof to say that humans are not evolving. In fact, there is evidence that evolution is happening at this very moment. For example,

Introduction To Evolution What is Evolution? Evolution is the process by which all living things have developed from primitive organisms through changes occurring over billions of years, a process that includes all animals and plants. Exactly how evolution occurs is still a matter of debate, but there are many different theories and that it occurs is a scientific fact. Biologists agree that all living things come through a long history of changes shaped by physical and chemical processes that are still taking place.

What is Evolution? You might think of evolution as a mutational problem, which fits with the situation but it is not just that. Evolution is actually the change that appears to happen in a certain population over time. When I say the word “population” I am saying it is a group of the same species that happens to share the same specific location and habitat. Evolutionary changes often occur all the time near the genetic level. What I am actually saying is that evolution is a process that will result in many changes in which are passed on or inherited from generation to generation. It does not, for example, describe how some people can just so happen to change their muscle mass by lifting weights or exercising. It is saying that generations

Homologous structures are anatomically and functionally similar structures in different species, which act as evidence that they have descended from a common ancestor. An example of homologous structures in the brain between different taxa are the palaeostriatum primitivum of the avian brain and the globus pallidum of the mammalian brain13. These structures show that is an evolutionary relationship between birds and mammals. In addition to looking at homologous structures, it is possible to look at the adaptive radiation of species which have been evolved independently and find examples of convergent evolution. Convergent evolution refers to when a trait evolves in different species independently of each other. Evidence of convergent evolution in turn proves the natural selection mechanism of evolution since it demonstrates that certain traits provide fitness, allowing the trait to survive in succeeding populations. There is evidence to show that certain aspects of brain anatomy in insects have evolved independently of each other in species such as butterflies and bees. The name of the specific piece of anatomy that exists in both organisms are is the corpula pedunculata or “mushroom bodies” (MB) which are responsible for navigation and spatial learning14. Both organisms had the necessity for an organ responsible

To demonstrate, the evidence for evolution with embryology, Jerry Coyne uses branchial arches, and the newly discovered phenomena called lanugo. To begin with, by comparing the embryos of fish with that of a human, scientist, have discovered how similar the embryos start out, but overtime their developmental process change to their specific species. In the fish, gills are developed, and in the human part of the head and middle ear. In a word, the discovery of that humans are covered with hair during conception, gives scientist better understanding of humans during their embryonic stage of life, because it proves the connection to our apelike ancestors. Final example used by Jerry Coyne, for embryology evolution is the grasping reflex by babies,

Biological evolution is the name for the changes in gene frequency in a population of a species from generation to generation. Evolution offers explanation to why species genetically change over years and the diversity of life on Earth. Although it is generally accepted by the scientific community, Charles Darwin’s theory of evolution has been studied and debated for several decades. In 1859, Darwin published On The Origin of Species, which introduced the idea of evolutionary thought which he supported with evidence of one type of evolutionary mechanism, natural selection. Some of the main mechanisms of evolution are natural selection, mutation, and genetic drift. The idea that all life on Earth shares a common ancestor has been around for

Evolution is the modification of characteristics of living organisms over generations (StrangeScience.net, 2015); it is the gradual process of development by which the present diversity of living organisms arose from the earliest forms of life, which is believed to have been ongoing for at least the past 3000 million years (Hine, 2004). Common ancestry are groups of living organisms that share the most recent common ancestor, by which scientific evidence proves that all life on Earth are descendants from the previous universal ancestor (DarwinWasRight.org, 2015). Additionally, opposing theories against Evolution, primarily the Christianity religion, explain that God is the ‘creator’ and is the source of all existence.

Eighty-seven percent of American scientists believe that a series of random chemical and biological events produced mankind. However, the philosophical "theory" of evolution has no solid evidence, whereas creation can be proven. Science is supposed to be based on observation, right? The best theories satisfy the test of experimentation. No one can test if evolution happened. Non one can prove that evolution actually happened. But what evidence can we place against evolution?

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.
