Evolutionary theories are fascinating in both their simplicity, and their explanatory power. In the past, some philosophers used examples of hugely complex biological arrangements as evidence for a designer, as opposed to theories which put the development of species down to chance. Charles Darwin, however, through making some simple observations, developed a theory that was simple and elegant, and yet could explain even the most complex biological structures without appealing to a designer.

One such intricacy is the human jaw bone. The amazing thing about this part of the human body, is that it seems perfectly suited to what we use it for, namely chewing our food, and forming sentences. It is just this suitability for purpose that theorists used to, and sometimes still, rely on to give weight to their theological conclusions. However, evolutionary theory presents us with a fairly simple narrative whereby we can explain the formation of this magnificent instrument, without appealing to the divine. What follows is a quick look at what such a narrative might look like.

The jaw bone of mammals, and so also that of humans, is a far cry from that of reptiles. But, as we well know, humans evolved, albeit over a very long period, from reptiles, so in order to explain the development of the human jaw bone, we need to explain how the reptile jaw bone became like the mammalian equivalent. A reptile’s lower jaw has several bones where the mammal only has a single one (the dentary). The evidence from fossils shows us that all of the bones, except the dentary, began to crowd towards the back of the jaw, over countless generations.

A theory which accounts for where these other bones eventually went to is that they became the bones that are not found the middle ear of mammals. Though this sounds crazy, it does not seem all that remote a possibility when you appreciate that reptiles hear with the bones in their lower jaw.

All that is needed, then, to give a plausible demystifying narrative of the development of the human jaw is the concepts of natural selection and evolutionary pressure, along with empirical evidence in the form of fossils. This theory also tells us something about how the complexity that is the human ear evolved.

The natural world has many different creatures, all with such varied characteristics that all seem perfectly suited to the environment they live in. In the past, people found this correspondence mysterious, and so it is understandable that they appealed to the divine in order to explain these phenomena. However, now Darwin has blessed us with the theoretical apparatus outlined in Origin of Species, we can explain all of these features in an extremely simple way.

The different teeth in different animals are a good example. In each kind of animal, the different kinds of teeth seem perfect for eating the specific food those animals eat, as if by design. For example, a carnivore enjoys a healthy set of flesh ripping teeth, such as their highly evolved fourth upper premolars, and first lower molars. These teeth have knife-like edges that shut like scissors. The fact that the jaw doesn’t open very far helps the animal to hang on.

Herbivores, however, have no need for such violent teeth, and so have less pronounced, or sometimes no canines at all. Their incisors are highly evolved, perfect for cutting grass; and they also have lots of flat premolars and molars for grinding their food up. So we know that each kind of animal has teeth that are particularly beneficial to their environment. But how does this come about?

Across many generations, there occur in nature small changes, or mutations, some of which will change the shape of animal’s teeth; but these changes do not have goals, and are random. So how do they seem to tend towards advantageous changes? That is where the concept of natural selection can help us.

When an animal has an adaptation that is advantageous, like a sharper fang in a carnivore, this animal’s chance of survival is greatly improved. Therefore, it is more likely that this animal will live longer to breed, and thus pass on its advantageous genes. It is the pressure imposed by the harsh environment, therefore, that ensures animals become better adapted to their environment, over many generations.

More than 360 species of birds have been seen throughout the Bay of Fundy area, including various rare animals like the peregrine falcon and the piping plover. Fundy is a preferred location for a lot of birdwatchers, especially during migration season, because of its unique location along the Atlantic Flyway. It’s computed that between two and three million birds fly along the Atlantic Flyway annually; 75% of those birds land in the Fundy area, making it the most important stopping point along the entire Eastern seaboard.

Mary’s Point Bird Sanctuary – located along the Fundy coastline in Albert County, New Brunswick between Fundy National Park and the well-known Hopewell Rocks – is one of the best spots along the Bay for spotting shorebirds, especially the semipalmated sandpiper.

Many thousands of semipalmated sandpipers land in Fundy each and every summer as part of their migration from their Arctic breeding zones to their winter home of South America. Why do they stop here specifically? Well, they come here to become fat. The birds follow the tide line as it advances and recedes. During high tide the sandpipers roost but when the Fundy tide start to recede, these tiny birds race from one hole to the next. Using sight and their relatively long bills, each sandpiper will eat between 9600-23000 mud shrimp every tide cycle. During their stay in the Bay of Fundy region, the sandpipers will double their weight of roughly 20 grams in order to build up their fat reserves to finish the remaining 4000km of their migration, non-stop!

In addition to Mary’s Point, these sandpipers have shown a stong liking for Grande-Anse, Starrs Point and Evangeline Beach. The first semipalmated sandpipers usually don’t arrive in Fundy until mid-July.

Another favourite bird seen in Fundy is the Atlantic Puffin. Located nearer the mouth of the Bay, Machias Seal Island is the temporary home to not only nesting puffins but also nesting arctic and common terns and razorbills. Access to this little island is limited and landing is done at your own risk as the shore can be quite slippery and uneven. The sanctuary is protected by the Canadian Wildlife Service.

The Bay of Fundy is a cool spot for bird watchers. And while you are there, you can also watch the famous Bay of Fundy tides!

German Shepherd breeders concentrate on keeping the basic characteristics of the true bloodlines of German Shepherds. None of them are fond of mixing the German Shepherd with other dogs. When searching for a German Shepherd you should go to the right kennel and observe the parents of the puppy in order to pick out the right puppy.

Looking online, you will find various websites allotted for German Shepherd enthusiasts where some of the best breeders and details about this type of canine are available.

As for high quality dogs, the Lane County Kennel in America is known for the red and black top line German Shepherd that they raise. These are nice show dogs, companionship dogs or even guard dogs because they have been trained for certain purposes. The breed is the Vom Haus Merkel bloodline. With more than 40 years of preservation and breeding experience for the German Shepherd breed, and the credentials of the stock can be verified. Absolutely authentic and imported German bloodlines are certified and can be traced back to SchH1, 2 or 3 and VA/V. Each of them has garnered high ranks in the Breed Survey Koerklasse 1. Apart from this there is an option to choose the Fleischerheim German Shepherds from the credible breeders in America who have four decades of experience in retaining pure bloodlines.

The Bay of Fundy is one of the most diverse marine habitats on earth and is thus the summer feeding ground for a lot sea mammals, seabirds and saltwater invertebrates. When you go on a Bay of Fundy whale watching adventure you should hope to see minke, fin- and humpback whales in addition to the rarest large mammal on the planet – the North Atlantic Right Whale.

Other animals often seen on whale watching journeys include harbor porpoise, dolphins, sharks, seals, bald eagles and a variety of seabird colonies, often including the Atlantic Puffin.

Bay of Fundy Whales

Minke Whale: The smallest and most common baleen whale (Fisheries and Oceans Canada, 2010), minkes are found in the Bay of Fundy across the summer season and well into the fall.

Humpback Whale: Also a baleen whale, Humpbacks are referred to as the acrobats of the sea as they jump above the surface. They’re also one of the loudest and most creative whales when it comes to vocalization and have the biggest range of frequencies. While there are roughly 10,000-15,000 humpbacks living in our seas, they are a species under threat. (EnchantedLearning.com, 2010)

Finback Whales: The second biggest species of whale on the planet, Finback whales are famous for being quick swimmers. Also a baleen whale, Finbacks are shielded under the Species at Risk Act.

North Atlantic Right Whale: Named for being the “right” whale to kill by 19th century whalers – due to its slow speed and thus ease of catch – the North Atlantic Right Whale was almost hunted to the point of extinction in the late 1800s. Today these wonderful creatures are on the endangered animals list with an approximate population of 425 remaining; a number that’s slowly rising (Fisheries and Oceans Canada, 2010). A massive portion of this population stops each August/September in the Bay of Fundy to feed enroute to their winter home.

New Brunswick Museum

The New Brunswick Museum, found in Market Square in Uptown Saint John, contains 3 floors of galleries and exhibits. In the “Hall of Great Whales”, a favorite gallery in the museum, hear the story of a North Atlantic Right Whale named Delilah who washed up on the coasts of Fundy, touch a chunk of baleen, learn engaging facts about minkes and humpbacks, and see skeletons and full-body models of several species of whales including the right whale.

Bay of Fundy whale watching tours are a popular activity close to the mouth of the Bay as the whales do not travel too far inwards. There are a number of great whale watching companies along either side of the Bay of Fundy who set out on the bay in a variety of vessels including catamarans, zodiacs, fishing boats and sailing yachts.

It is very common nowadays to hear the question: “how can I make my thick toenails thin?” The guidelines you will be given here will teach you how to turn those thick toenails thin and also keep them healthy. Prevention of the occurrence of thick toenails is possible if they are well looked after.

Age is a factor that needs to be taken into consideration when a person is suffering from thick toenails. It is a fact of nature that toenails thicken as a person gets older. This need not happen if good care is taken of the toenails in the earlier years. The top two reasons for thick toenails are injuries and fungal infections.

If the thick toenail is caused by a fungal infection the toenail will change color to a yellow or brown. If a fungal condition exists there will be some discharge of pus will occur along with a foul smell. This fungal condition is most often seen in runners and soccer players. Because of the stress being placed on their feet the nails become damaged and loose

The first toenail to be most affected by this condition is the big toenail. Another factor contributing to thick toenails is running or walking downhill. Thick toenails is not a condition considered to be harmful, but it does make trimming them very awkward. So to answer the question asked at the beginning of the article: yes, thick toenails can be made thin.

The thickness of your toenails can be lessened by regular trimming and proper filing. The most common tools used for the purpose of removing the excess are files and emery boards. If you feel that you are not capable of doing this on your own you can visit a podiatrist who will show you the correct procedure for trimming and filing your toenails.

While this is a simple procedure that can be done at home, anyone who is suffering from circulation problems or diabetes should speak to their medical worker before doing any trimming of their toenails. Circulation problems can cause you to harm your feet when trimming as the sensations are lessened due to the illness.

Usually for trimming extra thick toenails, they are soaked in warm water and lemon juice for ten minutes and dried thoroughly. Immediately after that the toenails are trimmed with a nail clipper and filed. Trimming of the nails should always start from the corner and nails should be cut straight. Initially, nails should be cut in small bits to avoid splitting.

If toenails are regularly checked and well looked after the chances of contracting thick toenails are very small. The most important part of preventing thick toenails is regular trimming and filing.

The Tainos were a pre-Columbian indigenous people living in the Caribbean region. Christopher Columbus met their large population when he landed on the island of Hispaniola in 1492. In two previous articles of this series we explored the history of the Tainos, and their status in present day populations of the Caribbean. We learned that although historians had previously declared the Tainos race to be extinct, one study done in Puerto Rico found that over 61% of the population had Amerindian mitochondrial DNA. Those results supported the findings of biology professor Juan Carlos Martinez at the University of Puerto Rico, who conducted his own studies. He suggested that the prevalence of indigenous mitochondrial DNA in people of the Caribbean may be even more than that of Caucasoid and Negroid.

The previously reported facts suggest a future for the Tainos, despite a complete loss of their language and the purity of their traditions. Through historical and archeological study we have learned the Tainos adopted numerous traditions, customs, skills and practices from other cultures they came into contact with. It is therefore difficult to determine what is a wholly Tainos characteristic, in some areas of the culture as it exists today. Yet despite the ambiguity of tradition, many people in Puerto Rico, the Dominican Republic, Jamaica, and Haiti identify themselves as descendants of the Tainos.

Many heritage groups have formed in the West Indies with a mission to foster Taino culture. Herein lies the controversy, partially because of the reasons mentioned above and partially through the knowledge of Tainos culture being blended with Spanish and African cultures. In reality there is no reason for argument over the purity of traditions practiced today. The implied genocide of the Tainos by the Spanish is a part of the history of the race, just as the adoption and blending of cultural methods, and now the re-emergence of Tainos pride.

There are numerous groups based all over the Caribbean dedicated to celebrating Tainos traditions and teaching future generations about their heritage. Since the original Maipurean language of the Tainos did not include a written component, some groups have created unique scripts. The ideas is to help strengthen interest in the Tainos, both by their own ancestors and by other cultures. Of course the argument here is the inclusion of a Tainos script is not true to the Tainos history because one never existed before. On the other hand, every culture on earth evolves and grows – why shouldn’t the Tainos?

The future of the Tainos is bright, no matter which side of the fence you sit on. There is scientific proof of the existence of Tainos DNA in the population. Heritage groups exist in each region the Tainos inhabited, all with an aim to promote their culture and traditions. Most importantly, there is awareness and appreciation of the unique history of the Tainos.
