Over the millions of years organisms have been present on earth, there has been many forms of evidence to suggest animals are evolving through natural selection. However, the question still remains as to whether homo sapiens are still evolving through natural selection. Through the nature of science being subject to change and many new discoveries being made each day, it is difficult to make clear confined theories and conclusions, which will not be impacted on in the future.

The four forces of evolution are Mutation, Natural Selection, Genetic Drift, and Genetic Flow. Each one of these subjects serves a high importance when speaking about evolution and how it has occurred over millions of years. Mutation is probably the most important as without the mutations, nothing else like natural selection can really occur. There would also be no variance in species and animals would look all the same or similar. With mutations, physical effects can be advantageous, fairly bad, or neutral with not much change and not good or bad. In natural selection, the idea of fitness is very important. As said in the lecture, this type of fitness doesn’t mean the physical attributes one has in order to beat out everyone because of their physicality, but instead it’s about the idea of one being able to produce fertile offspring in comparison to others. This selection

Evolutionary biology has always interested me, specifically the mechanisms of natural selection and how species adapt to their environment. It started with my love for animals and nature when I was little. I spent my summers working with horses at a local corral, where I would ride around the surrounding wilderness areas. My favorite part about riding in the mountains was watching the change in plant and animal species as the elevation changed. It never ceased to amaze me how the alpine tree line was always so sudden. Humongous pine trees would give way to the short, shrubby plants of the alpine tundra so uniformly and noticeably. I have always wondered about the environmental conditions that cause species to distribute themselves in

The definition of evolution is that species over time will change. They will start to adapt over time and become a new species. You see this happening throughout the world and over the course of our planets history. In this lab we will be testing different hypothesis and observing them to make conclusions if they can be justified or not. There are three different parts first is the Artificial and Natural selection, the second is the fossil record, third is comparative anatomy, biochemistry, embryology and the last is Biogeography.

Natural selection is the evolutionary process by which heritable traits that best enables organisms to survive and reproduce in a particular environment are passed to ensuing generations. Organism within the same species may develop new characteristics based on their environment to ensure their survival. The new genetic development within the species maybe then passed on to their offspring. Those within the species that do not develop a new characteristic to adapt to the altering environment are left prone to disease, deformities, and even death or extinction.

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

Evolution through natural selection is not a controversial topic. It is not controversial because religion preaches that the maker made each individual species. Many times religion teaches that each individual has a purpose and is created for a reason. Evolution claims that living species can change over time and give rise to new kinds of species, with the result that all organisms ultimately share a common ancestry. That being so, people can believe in both. In a religious view people can be correct and people who believe in evolution can also be correct. Evolution can be true for religion that the maker has made each individual species, he/she started it all with one species and through time the world has changed

What do a sponge and bird have in common? Believe it or not, they share a common origin. In the film, "Darwin 's Tree of Life," the narrator, David Attenborough, presents the audience with the theory of evolution as documented by Charles Darwin in the 1800 's. The video is based on Darwin 's perspective of evolution and natural selection. Darwin 's findings were revolutionary and caused out-rage among the religious who believed in the story of creation beginning with Adam and Eve. In the video, "Darwin 's Tree of Life," Darwin 's theory of evolution and natural selection proved the tree of life explains our evolution from a molecule to mammal.

Biological Evolution is any genetic thats changes in a population that is inherited over several generations.

Without evolution, and the constant ever changing environment, the complexity of living organisms would not be as it is. Evolution is defined as a process that results in heritable changes in a population spread over many generations (8).Scientists believe in the theory of evolution. This belief is based on scientific evidence that corroborates the theory of evolution. In Figure 1 the pictures of the skulls depict the sequence of the evolution of Homo-sapiens. As the figure shows, man has evolved from our common ancestor that is shared by homo-sapiens. The change of diet of homo-sapiens over time has thought to contribute to the change in jaw structure and overall skull shape.

Darwin came up with a good idea but the animals he compared were a bit too farfetched. Using a whale as an example of evolution by natural selection is an example which is still used today.

The four forces of evolution are mutation, natural selection, gene flow, and genetic drift. Mutations occur when the DNA replication process makes an error, if the error is not fixed than the mutation will form. A lot of the mutations do not affect an individuals health, however, there are some that can cause damage. If the mutation makes the individual stronger or benefits them, then the mutation is capable of staying within the population through reproduction. Natural Selection is when a species adapts to its’ environment and thus is able to reproduce while the others who have not adaptive die out. Darwin calls this survival of the fittest, only the strong move on. Gene flow is the process of breeding with a different population that changes

he four main forces of evolution are; mutation, migration, genetic drift, and natural selection. From my stand point I think the most important evolutionary force is mutation since it is the only way to create new traits, the other sources may just change gene frequency in a population, however, mutation is the only force that encourages new traits to emerge with I a population. Additionally, genetic drift and migration only have a big change on small populations. There is two examples of genetic drifts, one which is the bottle neck effect. This effect is imperative because it does eliminate one certain trait in the gene pool of a specific species, bottle neck effect for me is the most harmful to species because it might lead to extinction if the remaining trait undergoes natural selection and cannot survive. Alongside with genetic drift and migration natural selection is one of the most imperative when it comes to the impact of a

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
