What is Cystic Fibrosis? Cystic Fibrosis is a hereditary disorder affecting the exocrine glands. It causes the production of abnormally thick mucus, leading to the blockage of the pancreas, intestines, and bronchi and often resulting in respiratory infection. Another common name for Cystic Fibrosis is 65 roses. This name came about for the young children who were affected by this illness because it sounded similar.  This diagram is showing what a normal airway looks like and one that has been affected by CF Causes The causes of the illness is a gene called CTFR (Cystic Fibrosis Transmembrane Regulator), which makes a protein that controls how salt and water move in and out of the body’s cells. If you develop this is a baby or an adult that means your CTFR is broken. A bad CTFR gene is what develops the wrong amount of salt or water within your body. That’s what makes your mucus too thick or your sweat too salty. 

Where there is not a cure for CF there are many treatments to reduce the symptoms. Symptoms As your child grows older you could notice these symptoms:  This image helps understand the blockage the mucus does within our lungs.
 * Coughing up thick mucus.
 * Wheezing or shortness of breath.
 * <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">Getting sinus infections, bronchitis, or pneumonia often.
 * <span style="color: #000000; font-family: 'Times New Roman','serif'; font-size: 16px;"><span style="font-family: 'Times New Roman','serif'; font-size: 16px;">Weight loss or failure to gain weight

<span style="font-family: 'Times New Roman','serif'; font-size: 26.66px;">Treatment <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">Cystic Fibrosis is incurable to this date. However, there are antibiotics, inflammatory available, pain medication and inhaled medications called bronchodilators. There is treatment available known as chest physical treatment. This is a process to loosen mucus within your lungs and it is repeated up to four times a day. A method used is clapping with cupped hands on the front and back of the chest. <span style="font-family: 'Times New Roman','serif'; font-size: 16px;"> <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">This image is showing the mask used to breath in to loosen the mucus that had built up. <span style="font-family: 'Times New Roman','serif'; font-size: 21.33px;">Vest Therapy <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">A vest is placed on the patient’s chest and it vibrates to move mucus where it can be easier to get rid of or there is a tube or mask you can breathe into. <span style="font-family: 'Times New Roman','serif'; font-size: 16px;"> The vest he is wearing vibrates his chest to keep everything moving.

<span style="font-family: 'Times New Roman','serif'; font-size: 26.66px;">Purebred Dog’s And Their Health Risks

<span style="font-family: 'Times New Roman','serif'; font-size: 16px;">The definition of a purebred dog is <span style="color: #222222; font-family: 'Times New Roman','serif'; font-size: 16px;">an animal bred from parents of the same breed or variety. For example, german shepherds, golden retrievers and bulldogs. People began to cross breads to incorporate different features to certain dogs. This process was mainly for the appearance of the animal. To this day, there continues to be cross breading but it is for the health benefits of these animals we call mutts. There are two different selections, artificial selection and natural selection. Artificial selection is the process where organisms with the desired traits, such as size or taste, are artificially mated. Natural selection is where organisms better adapted to their environment tend to survive and produce more offspring. <span style="color: #222222; font-family: 'Times New Roman','serif'; font-size: 16px;">

<span style="color: #222222; font-family: 'Times New Roman','serif'; font-size: 26.66px;">The Transformation

<span style="color: #222222; font-family: 'Times New Roman','serif'; font-size: 16px;"> Due to individuals cross breading animals with no regard to the animal it has changed the appearance and health of many. Specific breeds were given traits to help them survive in their environment. Such as the Boxer, the Boxers muzzle has gotten smaller. Due to their pressed in face they experience difficulty in breathing in hot temperatures. Dog’s natural reaction to warm weather is to pant; therefore dogs with a flat or short muzzle have a more difficult time which can cause them to faint. <span style="color: #222222; font-family: 'Times New Roman','serif'; font-size: 16px;"> <span style="font-family: 'Times New Roman','serif'; font-size: 16px;"> The Dachshund in the past had functional legs and necks that made sense for their size. The dog’s backs and necks have gotten longer, chest increased forward and legs have shrunk to such proportions that there is barely any distance between their chest and floor.

<span style="color: #222222; font-family: 'Times New Roman','serif'; font-size: 16px;"> <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">The German Shepard is known well for being a police dog and their strong body. However, breeding have made their legs cave in thus causing them to have hip problems and to resemble a frog.

<span style="color: #222222; font-family: 'Times New Roman','serif'; font-size: 16px;"> <span style="color: #222222; font-family: 'Times New Roman','serif'; font-size: 16px;">This image shows the distortion between the English Bulldog then and now. Their heads have sunk in creating a short muzzle.

<span style="color: #222222; font-family: 'Times New Roman','serif'; font-size: 26.66px;">How we can help

<span style="font-family: 'Times New Roman','serif'; font-size: 16px;">Purebred dogs often suffer from the effects of inbreeding. The main problem with purebreds comes from the simple fact that to create a purebred puppy you need two dogs from the exact same gene pool. This creates the animals to pass down their genes, which limits the variety of genes in their pool. Risks include epilepsy, mobility issues, cancer and heart disease. All we can do to minimize the illnesses these dogs can develop is to cross bread or rescue from your local shelter. If you want a purebred it’s up to you but be aware of the consequences and medical bills in the future.

<span style="font-family: 'Times New Roman','serif'; font-size: 26.66px;">What’s next for human evolution? <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">Human evolution is the development of mankind over a length of time. Evolution like everything else plays a role with DNA (makes up our genes). Change or evolution is caused by a mutation in the DNA code. From time to time a mutation will occur, thus changing a particular trait or behavior. <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">This picture represents how advanced humans have become over millions of years and what stage we are currently at. <span style="font-family: 'Times New Roman','serif'; font-size: 26.66px;">How can we be certain that human evolution happened? <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">There are many reasons why scientists believe we have developed. For example, we share almost 99% of our genetic sequence with chimpanzees and bonobos therefore, suggests we share a close relation as an ancestor. Secondly, fossils have been proven to be different than the ones we previously found. Therefore, showing us that life on Earth is much different than it used to be.

<span style="font-family: 'Times New Roman','serif'; font-size: 16px;">Fossils are remains or traces of animals, plants and human life from the past. <span style="font-family: 'Times New Roman','serif'; font-size: 26.66px;">First Discoveries (The process of evolution) <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">The process of evolution involves natural changes to raise the population, adapt to the environment, and become extinct. Evolution does not change any single individual. Instead, it changes the inherited means of growth and development that typify a population. Parents pass down inheritance traits to their offspring, therefore creating a higher chance of survival and the ability to give birth, which could work well until their environment changes. <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">This image shows the development of animal to human. <span style="font-family: 'Times New Roman','serif'; font-size: 26.66px;">What’s the next step in human evolution? <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">Scientists believe modern technologies play a large role in how we humans will evolve in future generations. As previously stated, evolution is a complex and long process. By the time these things begin to affect mankind, this generation will be long gone. Here are some potential changes explained by theguardian.com; we could possibly develop color changing skin. Like chameleons we could consciously change the color of our skin if we were in danger, mating or to be accepted by other races. Secondly, selective hearing could be a possibility. Humans could develop the ability to actively "tune out" things they don't want to hear. Thirdly, flexible skeletons could develop. A benefit of this is easier birthing process and it would be less likely to get severely hurt by accidents.
