explain the species of the past and how they lived and have evolved over time. The only thing that gives direct proof to what existed in the past are fossils as they are the physical remains, in rock form, of what existed. Today's technology for scientists is in fact so advanced that they can tell what certain species ate, how long they lived, and obviously what they looked like. This helps when talking about biological evolution because it gives scientists physical proof of what species existed…
Koalas and Bald eagles can't live without their habitats keep getting destroyed or them getting hunted. Koalas are being hunted for there fur and the farmers were cutting down trees to make more farm land. The eagles are being hunted for the fun of it cutting down their habitats for more roads. Recent study on this majestic bird and this furry creature there protection efforts to don't cut down their habitats and hunting them. Scientist Bill Ellis been studying on koalas for many years and found…
Poison is a substance that through its chemical action usually injures, impairs, or kills an organism Carefully remove any remaining poisonous materials from your pet’s reach Check to make sure your pet is safe: breathing and acting normally Gather the container or substance, to bring to the veterinary hospital or to describe to a Pet Poison Helpline expert Collect a sample of any material that your pet may have vomited up. Your vet may use this for sample testing Call a Pet Poison Helpline or…
The human species is highly diverse and there are numerous physical variations amongst individuals. It is seen when looking at populations from around the world. Take for example someone from Europe and compare him or her to someone from Africa, the differences are noticed immediately. Whether the diversity of the human species due to physical variation leads to the existence of distinct races within the species is not yet settled. The concept of race can be looked at from two standpoints; the…
The Pittsburgh Zoo is only one of six combinations of a zoo and an aquarium in the United States. It displays an impressive “400 different species of animals, some of which are threatened or endangered” (USNews.com). Nonetheless, the Pittsburgh Zoo strives to fashion optimistic, lifelong relations between animals and people, and this goal is evident throughout the Zoo’s walkways and exhibits. As I walked throughout the Zoo, I noticed that the animal’s exhibits closely resembled their natural…
Pacific. During this journey he observed many new animals, geological formations, and plants, all the while taking copious notes and keeping in mind the idea of uniformitarianism (the present is the key to the past). He published his book The Origin of Species in 1859, detailing his theories concerning the origin of life in respect to the things he had observed throughout his voyage. It is interesting to note that this book was published more than twenty years after his trip and simply included…
How did they do this? Existing research had already demonstrated that 10 discovered species of Motyxia had different levels of bioluminescence. By measuring the variance in the brightness between species, the authors of the study attempted to gain an insight into how their bioluminescence evolved. An experiment was set up to measure the brightness of each species. The experiments used a number of wild species of Motyxia and a control group of closely related millipedes which do not have…
Introduction Squirrels are small rodents commonly known across the United States. There are over 200 squirrels species. They belong in the genius Scieridae(1). There size is varies from 5 inches to 3 feet long. The commonly known squirrel in Kansas is either the Eastern Fox Squirrel, its recorded size varies from 18-28 inches. The genus name for the Easter Fox Squirrel is Sciurus Niger(2). Animal activity can be measured in the observation of animals in a certain location. The Activity can…
these two species. History About 155,000 years ago, the Homo sapien has arisen from previous ancestors such as the archaic H. sapien and H. erectus (Rodrigues, 2012). Most of our ancestors were discovered and identified in…
This is another way we have evidence of relatives in evolution when finding that there are more closely related relatives. The author states, “We expect to find, in the genomes of many species, silenced, or “dead,” genes: genes that once were useful but are no longer intact or expressed” (Coyne, 2009, pg. 67). When another specie forms into another are basically genes that form ancestral structures. The author also talks about bad design…
