Essay on The Validity of the Theory of Evolution

The fifth part of the evolution theory is natural selection. Natural selection is an idea that life doesn’t require creation or guidance from a supernatural being. Natural selection depends only on nature in which the population will adapt to their environment while the one who are unable to adapt will die off. But natural selection cannot provide perfection but can only help the creatures to evolve just enough to be able to survive.

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.

Animals fight for survival daily, and sometimes their lives depend on their ability to adapt with their surrounding environments. Natural Selection is the process in which individuals have certain traits that allow

He finally observed that overtime these birds developed different physical characteristics to help them be able to survive and adapt to their surroundings. Darwin developed the “Natural Selection” theory that stated that plants and animals adapt to their surroundings and environments in order to survive. He also stated that older generations of these species would eventually die out, because they do not have the newer characteristics that needed to be developed in order to live.

“If no such variations exist, the population rapidly goes extinct because it cannot adapt to a changing environment” (O’Neil, 1998-2013). Scientists call this reproductive success. “Within a specific environment context, one genotype will be better than another genotype in survival or reproduction for certain reasons having to do with the way its particular features relate to the environment or relate to other organisms within the population” (Futuyma, 2000-2014). The theory of evolution is explicable through various kinds of scientific research.

The fossil record is evidence of evolution. Fossils are often fingerprints of evolution. They help scientists track how species evolved

Animals and plants had to change or evolve due to environmental pressures. Over millions of years the conditions on the Earth have changed tremendously, the environmental conditions we have now are very

In science, evolution is one of the basic templates to understand the biology of an organism or ecological unit. Changes in that ecosystem cause adaptations to occur in species, if there is time. With human intervention (pollution, climate change, deforestation, etc.) many species do not have time to adapt, and therefore move to a new environment or become extinct.

The definition of Evolution is ¨the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth,¨ (Dictionary.com, 2018). Although, the actual definition is hard to comprehend. Some consider Evolution to be a somewhat ridiculous topic that is far from true. Though others believe that, ¨Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology,¨ (Than, 2018). The main idea of Biological Evolution is that all life on Earth share a common ancestor. The term is a way of understanding life.

Fossils are prehistoric organisms or objects that have been preserved. How are fossils formed? Fossils can be formed in many ways. There are more ways that are common for them to be made for examples plants dying or animals dying and then they get buried in the mud. After a soft tissue builds around them and eventually turn into a rock. Fossils are a very important part of evolution.. Why? Well thanks to fossils scientist could see how organisms in the past looked like. If they ever find them at least . You can also see how old the other organisms were or how long ago they looked different . There is two types of fossils there is trace fossils and body fossils. Body fossils are like teeth from animals or bones. Trace fossils are like footprints,

In 1895 Charles Darwin published a book describing his theory of evolution, and his theory of the natural selection process. This theory caused much uproar in the religious community because Darwin’s theory went against the story of creation portrayed in the Holy Bible. His theory claimed that all life currently in place had evolved and adapted from a single organism in the beginning. Over time and by process of natural selection only the dominant species were left over while the other, less dominant species, went extinct. His theory, backed by scientific analysis, had dismissed the idea of a single deity creating all life on Earth. It is not like Darwin had a personal agenda against religion or anything,

Introduction: This report talks about evolution and four factors that contributed to evolution. The four factors are fossil record, geographical distribution, similarities in embryos, and homologous body structures. Evolution is the change of features over generations from different species of animals.

Many scientists in the past, such as Aristotle and Plato, believed that there were no changes in populations; however, other scientists, such as Darwin and Wallace, arose and argued that species inherit heritable traits from common ancestors and environmental forces drives out certain heritable traits that makes the species better suited to survive or be more “fit” for that environment. Therefore, species do change over a period of time and they were able to support their theory by showing that evolution does occur. There were four basic mechanisms of evolution in their theory: mutation, migration, genetic drift, and natural selection. Natural selection is the gradual process by which heritable traits that makes it more

Evolution refers to change over time as species modifies and separate to produce several offspring species.

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
