Ska music is best known for its up-beats, horn music, and the classic checkerboard icons associated with the musicians. However, many people don’t know the history of ska music. It is Jamaica’s first indigenous urban pop style, blending jazz, rock, rhythm and blues, and Caribbean folk music. Emerging in the late 1950s from an early form of rhythm and blues in Jamaica, it quickly spread to Louisiana, incorporating more horn instruments such as the trombone, trumpet, and the French horn. The horns and pianos play the riffs on the offbeat. The most well-known technique in the ska guitar style is the guitar chop, typically upstrokes on the offbeat. The ska chop is credited to Ernie Ranglin, one of the pioneering ska musicians. Ska has had many different “waves” of popularity over the decades. The first wave began in the early 1960s; the second wave in the 1970s, gaining popularity in the UK and eventually melting in punk and pop influences with artists such as the Specials; the third wave came in the mid-1980s, this time taking over America; the fourth wave of ska took over the media in the mid to late 1990s with groups such as No Doubt, The Mighty Mighty Bosstones, and Reel Big Fish bringing ska to the mainstream.

The traditional view of archaeologists usually involves a college professor who spends much of his or her time digging and researching in ancient foreign libraries or a museum curator who works every day to preserve the artifacts the museum holds. While this view isn’t completely incorrect, it is incomplete, both in terms of the types of jobs available to archaeologists and in the types of work within those jobs. For example, college professors may spend summers at dig sites, but much of their time is also spent writing grants, teaching students, and writing about their research projects. Additionally, although there are still many people who work in archaeology as professors and museum curators, the demand for these jobs far outstrips the number of positions available, making the positions difficult to acquire.  1

One of the easiest ways to see the way that earthworms change their environment is in the effect that the number of earthworms has on soil fertility, a measure of how hospitable an environment is to plant growth. Even the least fertile soil has around 62 worms per square meter, and as the number of worms increases so does soil fertility. As worms move through the different layers of soil, they eat, digest, and excrete massive amounts of organic matter. They leave their excretions behind in the form of nutrient-rich droppings known as casings. As these casings decompose, they release nutrients into the soil. This process not only moves nutrients from one layer of the soil to another but also converts the nutrients to forms that plants can absorb and process more easily.  1

At this point the author is considering the addition of the following table.

Ecosystems are made of a complex system of energy and nutrient transfers from one organism to another. Some of these transfers are in the form of predation: one organism eating another – while others are in the form of ecosystem engineering, an organism changing the environment around them. One major form of ecosystem engineering is niche creation, the process of an organism changing its environment to create a competitive advantage. In order for an organism to be considered as creating a niche, three things must be true: the organism must significantly modify its environment, those changes must affect other organisms’ survival, and those changes must lead to an evolutionary response in another organism. 1

One of the world’s most influential “niche constructors” - species known for changing the environment around them - is the earthworm, an organism found almost everywhere on the planet. Earthworms were originally aquatic organisms that were ill-equipped to survive on land. A scientist only concerned with evolution would predict that, in order to live on land, earthworms would have to significantly change. Earthworms didn’t change their physiology a great amount, however, instead, they changed the soil to make it more like the ocean in order to survive. Land with earthworms is less compacted, is more nutrient rich, and is better mixed than land without them, leading to monumental changes in the ecosystem.

To be considered true niche constructors, however, earthworms must change the environment in such a way as to alter the evolution of another species. One of the easiest ways to measure this effect on evolution is in the effect that the number of earthworms has on soil fertility, a measure of how hospitable an environment is to plant growth. Even the least fertile soil has around 62 worms per square meter, and as the number of worms increases so does soil fertility. As worms move through the different layers of soil, they eat, digest, and excrete massive amounts of organic matter. They leave their excretions behind in the form of nutrient-rich droppings known as casings. As these casings decompose, they release nutrients into the soil. This process not only moves nutrients from one layer of the soil to another but also converts the nutrients to forms that plants can absorb and process more easily. Because it is easier for plants to get the proper nutrients, plants don’t have to invest time and energy into making better root systems to gather nutrients. As a result, plants have, over time, lost some of these mechanisms – a form of evolution.

Without earthworms, modern land-based ecosystems would look very different. There is no way to predict the exact changes that would exist without earthworms, but it is easy to recognize earthworms’ impact. As research continues into the effect of earthworms, scientists are confident that it will show an even more complex picture of the earthworm’s contribution to the land-based ecosystem.

In recent years, there has been an influx of natural disasters, largely attributed to climate change. In January of 2019 alone, there were over 461 earthquakes with a 1.8 magnitude or higher in the California area. This led to a massive 7.1 magnitude earthquake in July of that same year. The foreshock, or beginning of the waves, occurred over 30 hours prior to the main event with a 6.4 magnitude. In November, Albania, across the world, experienced the deadliest earthquake of 2019 with a death toll of 51 and a magnitude of 6.4.

In 2018, the Atlantic hurricane season had 15 named storms, 8 hurricanes, and 2 major hurricanes. With over 100 deaths and $50 billion in damage, the 2018 season was the third consecutive above-average season. The first named storm, Tropical Storm Alberto, formed prior to the official start of the hurricane season, which is June 1st.

An amendment to the United States Constitution occurs when Congress proposes an amendment, or change to the current Constitution, which is then sent to the states to be ratified. Since the inception of the United States, there have been a total of 27 amendments ratified and over 11,770 proposals since 1789 (as of January 2019). The first amendment to be ratified in the 20th century was the 16th amendment on February 3, 1913, which was the beginning of income taxes as we know it today. Between 1913 and 1992, 11 Amendments were passed, among them: The right to vote regardless of sex, the manufacturing or sale of alcohol (which was later repealed in 1933 via the 21st Amendment), limiting the amount of term limits for a president, and granting the District of Columbia electors for the Electoral College.

Dogs are known to have a shorter life span than humans, but what dog breeds live the longest? The average lifespan of a dog is about 10-14 years and external factors such as diet and exercise can lengthen or shorten their lives, as with humans. Chihuahuas are one of the longest living dog breeds, living an average of 15 years, and even as old as 20 years. Dachshunds typically live an average of 15 years as well. The Guinness world record for the oldest living dog was set by Dachshund at 21 years old. Toy poodles are also known for their longevity, living up to 18 years old. Many Toy poodles experience orthopedic problems and eye disorders as they grow older. Jack Russell terriers are another breed that often reaches 16 years old. Smaller breeds tend to have a longer life, and the Shih Tzus prove it by rounding off this list with a common lifespan of 15 years or so. This breed also has predispositions to eye issues as well as other health conditions.

There is an abundance of diets to choose from, deciding which one is the best fit is almost as hard as the lifestyle change. There have been many diet fads throughout the years, each claiming to be better than the last. With several studies, many scientists set off to find the perfect diet. The low-carb, whole food diet helps people who are looking to lose weight, lower their risk of disease, and improve their overall health. This diet aims to eliminate any processed foods, which can be bad for our system. This diet is high in vegetables, meat, fruits, nuts, and fats, but low in sugars, starches, and processed foods. The Mediterranean diet is one that helps with heart disease prevention. It emphasizes foods eaten in the Mediterranean region such as vegetables, fruits, fish, poultry, grains, beans, dairy, and lots of extra virgin olive oil. The Paleo diet is a newly popular diet that helps with weight loss and general health improvement. It also focuses on unprocessed food, having a diet much like our nomadic human ancestors, consisting of fish, meat, fruits, vegetables, legumes, and some grains. The vegan diet has been steadily growing in recent years, and has been linked to a number of health benefits, such as weight loss, improved heart health, and better blood sugar control. Most vegans see this more as a lifestyle than a diet, as their focus is on preventing harm to animals, eliminating any and all animal products such as dairy and meat, focusing on plant-based foods. The Gluten-free diet became very popular in the mid-2010s, which came with an awareness of Celiac Disease, or gluten intolerance. Gluten is found in any product with wheat, rye, and barley.
