Mating

grounds based on climate change other related environmental factors (Peter A. 2003). This is a very important key to their reproductive success and fitness. So when these groups of birds arrive too early to their new location, they will face a hard time mating since the temperature will not be their favorable one and therefore it will be survive in climates that they are not used to. This will ultimately not help the population to evolve. For example, birds such as hummingbirds are extremely…

influence reproductive behavior such as menstrual cycles and mate selection. Their purpose in humans is less studied, and it is quite possible that we have evolved to be less influenced by them as social structures became more concrete. In modern culture, mating is commonly influenced by social standing or wealth, compared to older concepts such as choosing a strong mate. In the end, I strongly believe that most people can live long and fulfilled lives even without a sense of smell. While we…

Appearance, diet, habitat, natural (or introduced) predators, and reproductive habits Polar Bears live in an arctic marine ecosystem, and its native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. Polar bears have a distinctive white appearance. Their necks are much longer and their head is narrower compared to other species of bears. The front paws are large and used like paddles for swimming. Paws are heavily furred…

homozygosity is what causes the increased susceptibility to disease in many pedigree breeds. This is displayed through the bearded collie, which has an average inbreeding coefficient of 14.9%, higher than the equivalent of a grandparent and grandchild mating (12.5%). This level of inbreeding has resulted in the breed becoming more susceptible to Addison’s disease, an autoimmune disease that affects the adrenal glands, resulting in an adrenal insufficiency in the body. Although not…

The Hammurabi code was a very questionable code of laws which most people (at least the sane ones) deem unfair. The reasons for why it’s unfair vastly outweigh the reasons for why it is fair. It’s unfair because rich men are treated better than everyone else, slavery was pretty bad, and the lower classes were treated awfully as well. There are many examples of these subjects which are pretty unfair in the eyes of the modern man, and also the people back then I'm sure. The first subject that…

The readings for this week consisted of reading chapters one through five of Morgan Giddings “4 Steps to Funding; Avoid Rejection and Get Your Grant Funded on the Next Try With This Simple Four Step Formula”. As the title states, Giddings’s work is about how to write grants in a way that will ensure the grant writer obtains funding. Giddings’s writing reads like an infomercial, and while it may seem silly at first, it makes valid points on how to write a grant. Giddings addresses the need for…

colorful and extravagant feathers that appeared to have no benefit to the bird’s survival. With further observation of these male birds, Darwin established that these maladaptistic feathers were useful mechanisms to attract female partners for sexual mating. Through the conclusions on sexual selection and maladaptive traits, one can conclude that the primary action within the animal kingdom is not conquering, but reproducing, highlighting the significance of females within the natural world.…

For this lab we conducted a population genetics study on the frequency of wild and apterous flies within a small population of fruit flies. The fruit fly Drosophila works well for genetic and evolutionary geared studies because they have a relatively short generation time but are intricate enough to reveal some biological principles that are parallel to many different kinds of eukaryotic organisms. When exposed to artificial selection in laboratory experiments, fruit flies have experienced…

Before an in depth analysis about the visual perceptions of both the common barn owl (Tyto alba) and the white-tailed deer (Odocoileus virgiriianus) can be provided, it is important for the reader to understand the environments of which these organisms can from. Unlike the Odocoileus, the Tyto genus are nocturnal, medium sized creatures with white-brown fur, and are found in almost all parts of the globe except Antarctica (Harris, 2002). In regards to the courtship ritual among these owls, it is…

Humpback Whale In this paper, I will discuss a Humpback Whale biome of their choosing as an animal from that biome. I will explain how a humpback whale lives in weather and their biome. Also, I will explain where does a humpback whale live at in different oceans. The humpback whale is a species of baleen whale. A humpback whale is one of the larger rorqual species, adults range in length from 12-16 meters 39-52 feet and weigh approximately 36,000 kilograms 79,000 pounds. The humpback has a…
