We call the formation of fossils “fossilisation”. Fossils form in a really unique way, and it depends on several factors. It is quite hard to have all the favorable conditions to form a fossil. The corpse of the dead animal is usually eaten, or it is even affected by the presence of bacteria before the process of fossilisation can start. Erosion and corrosion are also responsible for destroying harder parts of the body, such as the bones. In order for the process

Evolution is a change in the characteristic of living organism through time. Modern synthesis, one of the greatest intellectual achievements of biology, could explain how mutations and natural selection could produced large-scale evolutionary change. There are 4 mechanisms for evolution to occur; mutation, gene flow, genetic drift and natural selection.
Although, there are a number of misconceptions about evolution; it does not explain the origins of life, it is not progressive, natural selection is not about the survival of the fittest individuals in a population, humans are not currently evolving, it does not make organism better designed nor does it gives organism what they need to survive. This essay will describe further, 3 common misconceptions

What is evolution? Evolution is a change in the traits of living organisms over generations. Since the development of modern genetics in the 1940s, evolution has been defined more specifically as a change in the frequency of alleles in a population from one generation

Define evolution? A slow change of something into better form. The word evolution means change, and the process of evolution reflects this definition as it applies to populations of organisms. Biological populations are groups of individuals of the same species that are sub-divided from other populations by geography and are somewhat independent of other groups. Biological evolution, then, is a change in the characteristics of a biological population that occurs over the course of generations. The changes in populations that are considered evolutionary are those that are inherited via genes. Changes that may take place in populations due only to short-term changes in their environment are not

Evolution is the change in the inherited characteristic of biological populations over successive generations (Wikipedia). The most notable theory of evolution was Charles Darwin’s speculation about natural selection. Natural selection is the process by which nature rewards those individuals better adapted to their environments with survival and reproductive success, defined by Ker Than, a Senior Editor in TechNewsDaily on livescience.com. Darwin published the first edition of “The Origin of Species” in 1859, in which Darwin theorized how a bear can turn in to a whale by natural selection. "I can see no difficulty in a race of bears being rendered, by natural selection, more aquatic in their structure and habits, with larger and larger mouths, till a creature was produced as monstrous as a whale," Darwin speculated (Than).

Evolution is the idea of a living organism adapting or mutating to gain beneficial physiological, psychological and structural features. The genetic makeup of all living things is constantly changing, due to DNA replication errors or outside factors, some of these changes impact drastically on the organism changing it for the better or worse. Typically when an organisms genetic code is changed for the better and it reproduces and outlives its unchanged counterparts this process is called evolution.

Fossils are very useful in putting together the history of organisms and how things have evolved over time. They can be found deep in the ground. The long process that makes this possible is fossilization. Fossilization is the process by which the remains of a plant or animal fail to fully decompose and in time, converts into a fossil. In order for organisms to turn into fossils, certain conditions must be met. The soft parts of an organism will often decompose or be consumed by scavengers. Therefore, organisms with hard parts like a shell are more often fossilized, leaving behind the skeleton. Even hard parts such as the skeleton can be destroyed by nature such as waves or by other microorganisms. Most importantly, the chances of fossilization decrease with greater exposure to

For my “out of classroom” experience, I attended an introductory class for the green dot training program provided by Bergen Community College. The host was Deborah Ajagbe who is the Bystander Intervention Facilitator and the Green Dot Coordinator. Her opening statement was how she desires to create a safer community not only in college campuses but everywhere. She presented us with a map covered in red dots at places such as schools, homes, stores, and parks. The red dots represent a “hit”, or a place where abuse in some sort of form takes place. It can also be a scene where violence is tolerated. However, the green dots symbolizes a “safe” zone where violence is always spoken against and where people choose to reduce harm. Proactive green

Evolution is the change in heritable characteristics of organisms  over time. Evolution was developed by a man named Charles Darwin in 1859. Charles said that evolution happens over time and when two species split into two. There are two ways that Charles came up with that show evolution , the first one is by Natural Selection. Natural Selection is when some organism are better at surviving than others , like if a giraffe with a short neck and a giraffe with a long neck . The giraffe with the long neck is going to survive longer  because the giraffe with the short neck will not be able to get as much high leaves as the other giraffe. The other  way is by inherited traits , like with the giraffes sense the giraffe with the long neck has more

More small leafthoppers was left, and there was less orange and large leafhoppers. Small leafhoppers may have the capacity of better heat dissipation than the larger ones, they have metabolism that is more suited to global warming. The leafhoppers with lighter color have a difference in their metabolism and it may explain their situation. A possible reason as to why they were unable to survive as efficiently as the darker ones is because their energy calorie needs was higher to produce offspring in warm climate. It is possible that color is linked to characteristics that are passed on to future generations, but color itself does not necesseraliy have a real direct role for survival.

Most people would be surprised to learn that scientists have an interest in rubber ducks. However, by tracking the journey of 28,000 rubber ducks and other toy animals, scientists gained extremely valuable information about the oceans.

Have you ever wondered how fossils form in the environment? Will, if you didn’t this is for you. The first stage of the “Fossilization” is when a type of animal dies in a watery environment and is then covered by mud. Then the soft tissues like muscle decompose leaving behind the hard bones, and maybe shells. Next, over time minerals like rock, soil, and others settle over the bones and hardens them to rock along with the others. Then you have your fossil. One of the most unusual fossils is when

In the pacific northwest, there exists an insect the size of an apple seed. It feeds on the phloem of trees, leaving them mutilated, their bark eviscerated and leaking sawdust. Victims of choice include lodgepoles, western white pines, and ponderosa, but any gymnosperm will do. For the mountain pine beetle, Dendroctonus ponderosae, the invasion means reproductive success. For the tree, it means slow death.

The Theory of Evolution was created by Charles Darwin and also Alfred Russel Wallace in 1858. The Theory of Evolution is based off of a branching tree of life that believed all shared the same common ancestors. Natural selection is the survival and reproductive outcome of random varying organisms. The evolution is change in genotype, which is allele frequency and over time it gives rises to all the different and diversity of species. Natural selection changes a species in many different ways. It can change by the population, climate, size and color over the time period of several generations. Microevolution and natural selection are very similar. Microevolution is the change in evolutionary with in a species or within a smaller group of different

Biological evolution is the name for the changes in gene frequency in a population of a species from generation to generation. Evolution offers explanation to why species genetically change over years and the diversity of life on Earth. Although it is generally accepted by the scientific community, Charles Darwin’s theory of evolution has been studied and debated for several decades. In 1859, Darwin published On The Origin of Species, which introduced the idea of evolutionary thought which he supported with evidence of one type of evolutionary mechanism, natural selection. Some of the main mechanisms of evolution are natural selection, mutation, and genetic drift. The idea that all life on Earth shares a common ancestor has been around for
