155 Words1 Page

the researchers found that muscle development in the fish is asymmetric. A lefty fish has a crescent-shaped body, with the muscles on the left side muscles more developed. The body of a righty is a the opposite. They also discovered that this asymmetry affects the way different species of fish interact with the bass. A righty bass hunts and eats more lefty baitfish, while a lefty bass consumes more righty baitfish. They then conducted fishing experiments in order to research the connection between body asymmetry and predatory behavior. They used the position of the hook set in the mouth to show the direction the fish was moving in when it took the bait. Righty fish had more hooks set on the right side, whereas lefty fish had more on the left

They discovered that two patches of tissue essentially control the development of limbs. Neil explains to us that the patch of tissue that makes the pinky side different from the thumb side is called the zone of polarizing activity or ZPA. Later, geneticists working with flies discovered a gene they called hedgehog. This gene controlled which end of the fly was which.

    Your Inner Fish essay In Neil Shubin’s Your Inner Fish, he takes his readers on a journey throughout time, teaching how marine animals inevitably ended up on land. Shubin starts his book by describing how himself and other paleontologists found a missing piece, that showed how animals transitioned from water to land. With this discovery it allowed paleontologists like Shubin, to see transitions that could possibly link certain species of fish to humans. A major change between fish and humans is the use of limbs and its ability to use its limbs to take itself out of the water and away from the dangers within.

    Joshua T. Brooks Professor Patty Chaffin English 111 8 February 2023 Blackfish Blackfish is a documentary filmed in 2013 directed by Gabriela Cowperthwaite. This film was produced following the lawsuit against SeaWorld where people have died while training with killer whales. Occupational Safety and Health Administration (OSHA) ruled that it was dangerous for humans to be in the same water as Killer Wahles in captivity because the only deaths by whales have come from them being in captivity, there have been no reported deaths by whales that live in the wild. This shows that you do not know how animals will react when you get them into the wild. Gabriela Cowperthwaite shows all of Ethos, Pathos, and Logos in the film.

    There is a common misconception about the field of paleontology. Many people believe it’s boring, that it’s irrelevant, and that it’s even a waste of time. However, as award winning paleontologist and author Neil Shubin argues in his novel, Your Inner Fish, the field of paleontology has the potential to change the way we view our bodies. Shubin rose to fame in the mid ‘00s after discovering a brand new fossil on the coast of Ellesmere Island. This fossil was of a creature that was part land animal and part fish, containing the flat head and joints of a land animal and the fins and webbing of a fish.

    As a secular person who takes an interest in science, I have always been fascinated by the academic field of evolutionary biology. Because of this, it should come as no surprise to anyone that the book I chose to review is entitled Your Inner Fish: A Journey into the 3.5-Billion-Year History of the Human Body. Written by Neil Shubin, this piece aims to outline the origins of humanity, as well as present a plethora of compelling pieces of evidence for the theory of evolution. He does this by reviewing scientific discoveries in areas of comparative anatomy, genetics, and the examination of fossils. Interestingly enough, he also integrates some of the most basic senses that we possess, such as sight and smell.

    Gabriela Cowperthwaite’s Blackfish (2013) and Louie Psihoyos’ The Cove (2009) both use music and sound effects to reinforce and compliment the visuals, keep the audience engaged, and highlight conflict, as well as employ interviews and archived footage to add a degree of credibility to their films and persuade the audience to sympathise with their cause. Both documentaries focus on animal rights activism, more specifically Blackfish is centred around the captivity of killer whales at SeaWorld, whereas The Cove addresses the mass dolphin slaying in Japan. Both Cowperthwaite and Psihoyos use music and sound effects in their documentaries to reinforce and compliment the visuals. For example, at the beginning of Blackfish, a recorded 9/11 emergency call complements a visual transcript, giving the

    The trappers are shooting back at them. Although if you look closely, the trappers are on the strength side of the frame which is the right and the natives are on the weak side which is the left side. Which side is the real dominant? The simplest form I can explain is this, have you ever been in a situation where two people want two people want to fight and they say back in forth “You better walk away”, “don’t mess with me”, “If you come closer, I will hurt you.” The irony in that situation is that in reality both persons do not want to fight, but if they show some sort of weakness, then they have lots the fight already.

    The simplicity of the cartoon does a fine justice to offer an insight on the intricacy and the visibility of the segregated social groups in our society. The cartoon elucidates the partitioning of different groups based on power, resource, and status with those who encompass the elite group, those who encompass the unjustified and underrepresented groups, and those who encompass the intermediate group that either oscillates towards one side or remains stagnant and satisfied with the status they already occupy. The big fish serves as a paradigm for those civilians occupying the elite group. The members in this group, according to Miller, establish the hegemonic society and attain the greatest influence in determining the culture’s overall outlook

  • There Is Mimicry In To Kill A Mockingbird

    In an evolutionary biological sense, mimicry can be defined as a similarity of one species (the mimic) to another (the model) as a protective mechanism for either one or both species, against another species (the signal-receiver or the audience), typically a common predator of both species. The stimulus occurs as appearance, behaviour, sound or scent. The model is usually another organism, with the exception of automimicry. For prey species, mimicry strategies evolved as an adaptation against predators within their environment. The selective action of a signal-receiver drives the evolutionary process.
