After many, many mutations, nature, and the conditions that early human ancestors had to live in, favoured better eyesight. In support of my argument that the eye is not intelligently designed, Professor Trevor D. Lamb goes on to say that “The vertebrate eye, far from being intelligently designed, contains numerous defects that attest to its evolutionary origin.” Some if these defects are: blood vessels across the surface of the retina, the optic nerve creating a blind spot, and an inside out…

“It is no the strongest of species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.” This quote was once said by the father of evolution himself, Charles Darwin who spent his life’s work on learning all he can about evolution. In the world we live in all organisms change, and were not the same thousands of years ago as they are today. There are two main theories to this process; scientific theory and religious theory. Many people go…

About 25 million vertebrate animals are used yearly in research, testing and education but it is unknown what purposes they are used for. The most common animals used in research (ordered from most to least frequent use) are mice, rats, birds, rabbits, guinea pigs, hamsters…

Natural selection is a key mechanism of the evolutionary process and relates to the occurrence of certain traits within a population and they way in which these traits affect the survival and reproductive success of an organism. Organisms need to be able to adapt to their environment in order to survive and reproduce. Any advantageous traits that occur within a population increase an individual’s chance of survival, thus resulting in the organism producing more offspring than those who have not…

Durand, in her essay, Ecology of Poetry, argues that the form and function of poetry, and especially of ecopoetics, should aim to reflect ecological processes rather than follow traditions of earlier nature poetry, which can be characterized by the ‘thingification’ of non-human objects through the view of human-subjects when perceiving natural object-landscapes, -animals, -organisms, etc. While modern human understanding of our interactions and relationship with our environment has cleaved us…

The decline in bees has been a controversial topic that has gradually garnered public attention over the last few years. With nearly 87% of all flowering plants (Ollerton, et al. 321), and 35% of global crop production (Klatt, et al.) being reliant on animal pollination, bees are a vital contributor to food production. Unfortunately, the bee population has been dropping steadily for the last 60 years due to factors such as, pesticides, invasion of pests, and climate change (Walters 375).…

Adopt a Bunny | Save a Rabbit It is safe to say that you are thinking about adopting a rabbit? Rabbits are delightful. They are delicate, calm and simple to house train. Much like a feline, they will use a litter box. Rabbits, not at all like felines, require supervision in your home. Rabbits make awesome indoor pets. Rabbits were first trained in the Middle Ages and are utilized as wellsprings of food, hide, and fleece, as research subjects, and as pets.. They are lovable and brimming…

that can be used to help solve questions of glacial history and past fauna and climate (Larsen et al., 268). The researchers found “2 m of laminated clay, representing deposition in a subglacial lake. From immediately below this clay a diverse vertebrate fauna of marmot, vole, marten, cervid and various species of birds and fish was recovered, yielding ages of 18–16 ka. The fish species indicate that relative sea level was close to the cave and that salmon runs were likely present” (Ward et al.…

Pick 3 of the following and argue that the following are either “adaptive” or necessary for survival, homeostasis, and/or reproduction: 1. Adluminal compartment of seminiferous tubules • The adluminal compartment is made up of spermatocytes, spermatozoa and spermatids. The compartment is considered a tight-junction. This tight-junction is said to be a blood-testicle-barrier. This means the…
