Most relating, but not limited to chocolate. The corporation plays a role in deciding where products are produced. Hershey’s has expanded to both Canada and Mexico, which calls for many corporate decisions. There are an amazing amount of products associated with Hershey. These include Jolly Ranchers, Hershey Kisses, Hershey drink mixes, the entire line of Reese’s products as well as good old fashion chocolate bars. These products serve in the candy/snack foods division of sales. Society could do without them... but why would we want to? Hershey’s takes advantage of many different types of advertising. Television commercials and ads are very common. Sponsorships is also another very common way Hershey advertises. Hershey sponsors everything from ice skating shows, to racecars. The Hershey Food Corporation is very competitive so they need this type of advertising. However, the only other major corporation to compete with is Mars. The chocolate industry is diffidently not pure competition. Mars and Hershey’s form an oligopoly. Hershey’s has so many different kind of products that they have a lot of competition. The company has branched out to where they’re not only competing against other chocolates but also for fruit candies, and baking chocolate and chocolate drinks as well. The fact that so many products are offered, extends the corporation to different divisions. Mexico and Canada have manufacturing plants. Seventeen manufacturing plants include Hershey, Pa (Hershey plant, Reese plant, West Hershey plant0, Hazleton, PA, Lancaster, PA, Memphis, Tenn., Naugatuck, Conn., New Brunswick, NJ, Oakedale, CA, Palmyra, PA, Reading, PA, Robinson, Ill., Stuarts Draft, VA, Wheatridge, CO, Dartmouth, Nova Scotia, Montreal, Quebec, Smiths Falls, Ontario, and Guadalajara, Mexico.

500 Million Years of Fish Evolution

500 Million Years of Fish Evolution Compared to dinosaurs, mammoths and saber-toothed cats, fish evolution may not seem all that interesting - until you realize that if it werent for prehistoric fish, dinosaurs, mammoths, and saber-toothed cats would never have existed. The first vertebrates on the planet, fish provided the basic body plan subsequently elaborated on by hundreds of millions of years of evolution: in other words, your great-great-great (multiply by a billion) grandmother was a small, meek fish of the Devonian period. (See a gallery of prehistoric fish pictures and profiles, a list of 10 recently extinct fish, and a slideshow of 10 Prehistoric Fish Everyone Should Know.) The Earliest Vertebrates: Pikaia and Pals Although most paleontologists wouldnt recognize them as true fish, the first fish-like creatures to leave an impression on the fossil record appeared during the middle Cambrian period, about 530 million years ago. The most famous of these, Pikaia, looked more like a worm than a fish, but it had four features crucial to later fish (and vertebrate) evolution: a head distinct from its tail, bilateral symmetry (the left side of its body looked like the right side), V-shaped muscles, and most importantly, a nerve cord running down the length of its body. Because this cord wasnt protected by a tube of bone or cartilage, Pikaia was technically a chordate rather than a vertebrate, but it still lay at the root of the vertebrate family tree. Two other Cambrian proto-fish were a bit more robust than Pikaia. Haikouichthys is considered by some expertsat least those not overly concerned by its lack of a calcified backbone - to be the earliest jawless fish, and this inch-long creature had rudimentary fins running along the top and bottom of its body. The similar Myllokunmingia was slightly less elongated than either Pikaia or Haikouichthys, and it also had pouched gills and (possibly) a skull made of cartilage. (Other fish-like creatures may have predated these three genera by tens of millions of years; unfortunately, they havent left any fossil remains.) The Evolution of Jawless Fish During the Ordovician and Silurian periods - from 490 to 410 million years ago - the worlds oceans, lakes, and rivers were dominated by jawless fish, so named because they lacked lower jaws (and thus the ability to consume large prey). You can recognize most of these prehistoric fish by the -aspis (the Greek word for shield) in the second parts of their names, which hints at the second main characteristic of these early vertebrates: their heads were covered by tough plates of bony armor. The most notable jawless fish of the Ordovician period were Astraspis and Arandaspis, six-inch-long, big-headed, finless fish that resembled giant tadpoles. Both of these species made their living by bottom-feeding in shallow waters, wriggling slowly above the surface and sucking up tiny animals and the waste of other marine creatures. Their Silurian descendants shared the same body plan, with the important addition of forked tail fins, which gave them more maneuverability. If the -aspis fish were the most advanced vertebrates of their time, why were their heads covered in bulky, un-hydrodynamic armor? The answer is that, hundreds of millions of years ago, vertebrates were far from the dominant life forms in the earths oceans, and these early fish needed a means of defense against giant sea scorpions and other large arthropods. The Big Split: Lobe-Finned Fish, Ray-Finned Fish, and Placoderms By the start of the Devonian periodabout 420 million years agothe evolution of prehistoric fish veered off in two (or three, depending on how you count them) directions. One development, which wound up going nowhere, was the appearance of the jawed fishes known as placoderms (plated skin), the earliest identified example of which is Entelognathus. These were essentially larger, more varied -aspis fish with true jaws, and the most famous genus by far was the 30-foot-long Dunkleosteus, one of the biggest fish that ever lived. Perhaps because they were so slow and awkward, placoderms vanished by the end of the Devonian period, outclassed by two other newly evolved families of jawed fish: the chondrichthians (fish with cartilaginous skeletons) and osteichthyans (fish with bony skeletons). The chondrichthians included prehistoric sharks, which went on to tear their own bloody path through evolutionary history. The osteichthyans, meanwhile, split into two further groups: the actinopterygians (ray-finned fish) and sarcopterygians (lobe-finned fish). Ray-finned fish, lobe-finned fish, who cares? Well, you do: the lobe-finned fishes of the Devonian period, such as Panderichthys and Eusthenopteron, had a characteristic fin structure that enabled them to evolve into the first tetrapods - the proverbial fish out of water ancestral to all land-living vertebrates, including humans. The ray-finned fish stayed in the water, but went on to become the most successful vertebrates of all: today, there are tens of thousand of species of ray-finned fish, making them the most diverse and numerous vertebrates on the planet (among the earliest ray-finned fish were Saurichthys and Cheirolepis). The Giant Fish of the Mesozoic Era No history of fish would be complete without mentioning the giant dino-fish of the Triassic, Jurassic and Cretaceous periods (though these fish werent as numerous as their oversized dinosaur cousins). The most famous of these giants were the Jurassic Leedsichthys, which some reconstructions put at a whopping 70 feet long, and the Cretaceous Xiphactinus, which was only about 20 feet long but at least had a more robust diet (other fish, compared to Leedsichthys diet of plankton and krill). A new addition is Bonnerichthys, yet another large, Cretaceous fish with a tiny, protozoan diet. Bear in mind, though, that for every dino-fish like Leedsichthys there are a dozen smaller prehistoric fish of equal interest to paleontologists. The list is nearly endless, but examples include Dipterus (an ancient lungfish), Enchodus (also known as the saber-toothed herring), the prehistoric rabbitfish Ischyodus, and the small but prolific Knightia, which has yielded so many fossils that you can buy your own for less than a hundred bucks.
