Introduction Speciation is the evolutionary process which occurs when a lineage split occurs in a species resulting in a new biological species. There are many ways by which speciation occurs 1) Allopatric specification; there are two types included in this type. Dicopatric speciation occurs when a species is isolated from each-other by geographical means and form subpopulations, if they remain separated for a long enough period of time they become genetically different that inter-breeding between

In Jared Diamond’s Guns, Germs, and Steel, the author proves a point that the formation of human history developed differently all over the globe because of science. Jared Diamond explained how this is true using facts from science. The author wrote that, “The fourth and last set of factors consists of continental differences in area or total population size. A larger area or population means more potential inventors, more competing societies, more innovations available to adopt- and more pressure

After looking into possible topics I was interested in, I decided I wanted to focus on the interplay of science and ethics. Moving forward, I decided I wanted to specifically examine the link between Genetics and Ethics—more specifically, the history and origin of Eugenics and its effect on human behavior. I have always been interested in the role of genetics in the growth of human civilization. Eugenics, which refers to the study of improving specific qualities of a human population or civilization

Story of the Human Body Synthesis Paper Candance N. Marshall Evergreen State College Story of the Human Body Synthesis Paper The chapters in the book start with the evolution of the human body from the lands of Africa to the present day. The findings of bones that date back millions of years displays the evidence of such evolution. The findings support the theories the changes the human body went through in order to adapt to its surroundings and the initial transition into a bipedalism species

Kelsey Williams Professor Reiner March 29, 2016 BIOL-108 Island Biogeography Lab Write-Up Purpose of lab: Calculating how many species were migrating to different islands Hypotheses: The main factors are island size and distance from the island. We hypothesized that islands close to a source area should have a higher number of species than islands further from the source area for islands of equivalent areas. Larger islands should have more species than smaller islands for islands

Glacier National Park History Glacier National Park was established as a national park on May 11,1910. The park was nicknamed the Crown of the Continent by George Bird Grinnell. The park bordering Glacier (Waterton Lakes National Park) was established in 1895. The two joined together in 1932 to create Waterton-Glacier International Peace Park.

In today’s ever growing world of science and technology, it is hard to discover something science can’t back up or prove. The modern world is infatuated with having science as a safety blanket for all their choices. From going on diets, to finding out tomorrow’s weather, modern society has adopted the phrase “because science says so” and turned it into a power wielding sword against opinions and beliefs. However, there is one thing modern science and technology has not been able to prove; whether

The Dolomedes raptor is a sexually dimorphic species of spider. The males have two white stripes on the edges of the cephalothorax; whereas the female has white stripes at the ends of the legs (Lin, Zhang, Liao, Hebets and Tso, 2015). These sexually dimorphic traits can be used in reproduction by attracting mates through the visual components found on each spider and may be used in the mating of the spiders (Lin, et.al. 2015). When females select a male, the attractiveness is correlated with the
