The Evolution Lab simulates environmental situations to determine effects on evolution over periods of time. This lab experiments with the evolution of finches on two different islands over 100, 200, and 300 years. By manipulating parameters that influence natural selection, the effects that natural selection have on the evolution process can be studied.

One thing about natural selection that many people do not understand that natural selection does not increase the odds of survival for a species, but for individuals in that species. This makes sense when someone considers humans. Humans live in many social cultures, where for instance, the odds of survival in a group can be improved by the selection of certain traits that does not improve an individual’s odds of survival. Coyne states, one never sees the type of adaptations that benefit the group to the detriment of an individual (p.122).

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

1. There are many ecological and biological factors that affect evolution. In EvolutionLab, two populations of finches are tracked over the course of 300 years on two different islands to see how changing the traits of the birds and their environment affect their long term viability as a sustainable population. Let’s begin by doing a “null experiment” where conditions are identical on the two islands.

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.

The environment determines which traits are most evolutionary desirable to an organism. If a population should move or should the environment change, a different set of traits would be the most advantageous

Space and time are linked, stars, worlds, and people are born, grow up, and die. Human beings live about 70-80 years, but the lifetime of the sun is 100 millions longer. Matter is older than life. Millions of years before the Earth was formed, atoms were synthesized inside the stars, and where thrown back out to space when they exploded. From this stellar remains appeared many planets; the Earth, and all living beings are formed from star’s dust, but from our human thinking, evolution has been really slow, from the molecules from the primitive oceans, up until the first bacteria. The reason why evolution is not the same for everyone is because is because it advances really slowly and lasts a long time. Why is it that if human beings who live 75

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

1) Compare and contrast evolution by artificial selection and natural selection. (Ch. 7) Natural and artificial selection for evolution are all processes which determine the genetic traits that will be passed to the next generation from the previous one. The main difference between them is that evolution by natural selection is mainly based on the species abilities to survive and reproduce, while artificial selection allows humans to control the traits that will be passed on to future generations, and the ones that won't be passed on.

Evolution plays several different roles in my life. An example, is when I am sick, I arrive at the doctor office and the doctor will provide a diagnosis and will give me medicine to heal the unwanted pathogens in my body and will provide medicine to completely eliminate them to heal the body and the unwanted infection. The infection becomes harmless to the body and in due time the infection will become healed.

There are many definitions of what constitutes an adaptation and a great debate amongst many famous biologists and philosophers, each championing their own definition of adaptation. Historical definitions include the ‘design’ oriented approach of Williams, who claims

Moreover, environments are constantly changing in regards to their climate, resource availability, species composition and physical structure; therefore, an organism with adaptations that are beneficial in one context, may be

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
