Now that we have covered what exactly an arthropod is and why they (specifically the uniramians class) are so successful, we can focus on one specific organism and look deeper into how they evolved to be so successful in the environment they are in today. The organism that we are going to be focusing on is the dragonfly. The dragonfly has been around for 300 million years and has manage to stay alive and thrive in its environments. Back then an ancestor of dragonflies roamed the planet, its name was Meganeura. Meganeura is a genus of extinct insects from approximately 300 million years ago, they are related to modern-day dragonflies. In this group one member known as M. permiana was first described be researchers in Kansas in 1937 as having a wingspan of over 2 feet or 0.6 meters long. It is still considered one of the largest insects ever to be alive on this planet. To better understand why prehistoric dragonflies were bigger than modern ones we must go back in time to take a look at what potentially happened and how the dragonfly evolved into what it is today. …show more content…
The wingless insects first appeared approximately 380 million years ago. The evolution of insects happened in four stages but for the dragonfly it appears in the second stage so we will only be looking into the first and second stages. The first stage is called the Apterygote stage, this term broken down basically means “without wings.” During this stage the simplest forms of insects were developed. They had no wings, or developed leg/ body parts. They also did not go through metamorphosis, instead they went through something known as ametabolous development. Ametabolous development basically means that the immature closely resembles the adult except for the presence of
This is a tale surrounding the dragons. There are 8 types of dragons each having a respected area. The Fire dragons and the volcanic gardens, The Ice dragons and their Ice mountains, The Electric and Air dragons and their Drakon Clouds. Water dragons has their Drakon Lakes, Magic are in the Orc Land, Forest on Omega Isle, and Earth in the Dragon Valleys. There have been many wars but at this time they are at peace.
espite their small size, sea dragons are carnivorous animals and therefore have a purely meat-based diet. The sea dragon uses its pipe-like snout to suck its prey into its oddly tooth-less mouth. Sea dragons hunt crustaceans, plankton, shrimp and even small fish, using their camouflage to their advantage. Sea dragons have numerous natural predators in the south and western coastal waters of Australia but are rarely even spotted to the elaborate camouflage of the sea dragon. Those few sea dragons that are unlucky enough to be found, are usually spotted by large fish. As with sea horses, it is the male sea dragon who care for the eggs once they have been laid by the female. The female lays around 250 eggs onto the long tail of the male sea horse.
The Leafy Sea Dragon is an interesting, thin, marine animal that I will be sharing information about to you. I hope you enjoy!

Introduction: Drosophila is the name given to a genus of small flies within the family, Drosophilidae. They are commonly referred to as fruit flies or pomace flies. They have historically been called vinegar or wine flies due to the fact that they commonly gather around rotting fruit. The fruit fly is sometimes mistaken for the Tephritidae family of flies which is closely related and is even sometimes referred to as the true fruit fly however; tephritids tend to only feed on unripe fruit, and have been regarded as destructive agricultural pests. For instance, the Mediterranean fruit fly has devastated the agricultural economy sector of several Mediterranean countries millions of dollars in ruined crops.
What causes fruit flies to have dichaete of vestigial wings is something called mutations. Mutations are, “Changes to the genetic information of an organism. Some mutations benefit the organisms, others harm it, and the rest have no notable impact whatsoever,” according to a Mutations article on Stemscopedia. In other words a mutation is any change in the sequence of DNA in a cell. The number of fruit flies with dichaete or vestigial wings is less than the number of fruit flies with regular wings because these mutations are rare. In the Mutations: Harmful or Helpful? article it states,
Subclass – Archeorinthes –*Fossil birds (Jurassic birds of Mesozoic Age). *Flight feathers present. *Long tail without a pygostyle. *Carpals and metacarpals free. *Abdominal ribs present. *Hand reduced to three digits.
The most extensive metamorphic changes of insects internal organs occur with development of the thoracic musculature required for flight, the arrangement of nervous system and the development of gonads [2].
Komodo Dragons are an amazing species of lizard, capable of taking down a water buffalo and yet these deadly beasts were not discovered until around one-hundred years ago!
Magic, something you only hear in fairy tales, see in movies, or the cheap fake illusions people use these days. To be fair there not that bad, but it’s not real magic. The kind of magic we uses is nothing like anyone has ever seen. How do we know magic you ask, well ever heard of dragons? Millions of years ago there were hundreds of dragons, which studied magic. Teaching each other magic. When the humans found out about the dragons power, they began to fear them even more.
Euthanasia is a long, smooth-sounding word, and it conceals its danger as long, smooth words do, but the danger is there, nevertheless, said by Pearl S.Buck. Euthanasia is a word of Greek origin that means easy death.However, is death just a simple task or is it a decision made from pain? Most people would agree that euthanasia is just used to avoid physical pain.Thus euthanasia should be illegal in Nevada. The three main reasons for this are: how depression often affects the decision, how guilt contributes to this decision, lastly a potential chance for fraud.
Scientists say reptiles evolved from amphibians 340 million years ago. The first reptile was an insect eater. Reptiles were more adaptable and able to
In the past, poverty was viewed as a ‘male issue’. Yet women are at greater risk of poverty than men and face different experiences of poverty. Staab (2015), argues that women face a lifetime of economic disadvantage, ending up with lower incomes and less access to land, housing and other resources to that allow them to maintain an adequate standard of living. Women are likely to be in poverty for longer stages including when they retire due to lack of pension. Therefore, it can be argued that there is a gender gap within social justice, with social justice for women failing to be achieved at the same level as it is for men.
What happens in the 48 hours after someone gets murdered and why is that the most important time frame for the case? A police department receives a 911 call that a homicide has just taken place and if this case isn't solved in the first 48 hours, then the chances of solving the investigation decrease dramatically. An investigator receives notice of a case, then he or she notes the date and hour of the call, the place where the crime was discovered and phone number of the person who called in the murder. Then Noted is how notification was received (radio, telephone, personal), who notified (name, number , etc), weather and geographical conditions at the moment, initial assessment
What's a dragon? A dragon's something a person may have to overcome to achieve the most great. Everyone has obstacles or a dragon that holds them back and make them it seem impossible to complete a goal. In reality, thank god our dragons are not fire-breathing killers like in Beowulf. Everyone has something different they would like to achieve. Whether it's graduating high school or passing a final exam. Some goals may seem bigger or harder to accomplish but really equally the same to others. I'm my senior year of high school, my dragon is to graduate high school and going to college.
