1. What does each letter in V.I.S.T.A stand for ? E level
Variation
Inheritance
Selection
Time
Adaptation

2. Using V.I.S.T.A explain how whales evolved from a land animal into the water only animals they are today. E-C-A
V
A very long time ago whales used to be land animals (pre whales). To survive they needed to move into the water because their environment changed and they needed food to survive.

I
But it wasn't like they could move into the water after one night or even a year. No, it takes time. Generation by generation. There would be pre whales with mutation (successive genes) that made them for example: hold their breath longer. Than they could go in the water and get their food.
Those pre whales would then mate and pass those mutations …show more content…

Pick three of the 'Evidence of Evolution' and explain how it's evidence for evolution. Then pick two of three and give '’evidence that, if found, would change our understanding of evolution’’.
E-C-A
1. Vestigial Features:
Certain organs or parts of organisms that becomes more basic in structure and have lower size and function during the evolution of the species.
An example of a vestigial feature is whale back flipper. When pre whales started to evolve their hind leg became smaller and smaller and if you look at the picture of whales evolving you can see that they have a very small back flipper. The bones in the back flippers looks like fingers or in this case toes because it’s the hind leg that has become smaller and unusable. And that is a vestigial features. Something that used to be use but no longer is and then becomes smaller and sometimes disappears.
This is a evidence because it provides evidence of genes for structures that are there but not because they are useful, but because they were once useful to an ancestor. Living organisms, including humans, has organs that were once functional, but isn’t anymore. They are either useless or have reduced function.
Vestigial features are by some evolutionists proof against creation (against religion). They think that a god wouldn't make organ that is

On the other hand the creationist say that, it’s easier to break something off than to create a total new organism. Breaking off something also occurs in the genes. My beginning thoughts on evolution were that they were true. I thought that animals evolved, I didn’t think humans evolved from monkeys. I didn’t believe that very intelligent organism can evolve from a monkey (of all

They hunted these whales, and ripped them from their family. They would always take the young ones away from their home. John Crowe, who was one of the many people that helped hunt the orcas, talked about how devastated he was to do that. They would grab the babies, but the family wouldn’t leave. They stayed watching them take their young and all he could think of was that this is equivalent to someone kidnapping a human child from their mother.

Vertebrates are known to be animals with backbones. Tooth reduction is one of the major evolutionary trends that developed among major vertebrate groups that allowed for the transition from aquatic to terrestrial life. Evolution of limbs and being able to breath air are other evolutionary trends that took placeThese trends include improved respiration and protective and insulating body coverings. More over the transition from water to land also included changing to more efficient reproductive methods like having a placenta for some animals or egg layers for other animals. Lastly, the morphology of organisms evolved such that for land they would have paired, muscular appendages used for crawling and

They also found that it was not just the largest whales that grew over time; the smallest whales found today are larger than the smallest extinct species. Further analysis revealed that the baleen whales had been diversifying in size for 30 million years; this began to take place between 4.5 million and a few hundred thousand years ago. The recent timing rules out the possibility that the emergence of gigantism was caused by the evolution of bulk filter feeding, large predators like giant sharks and falling global ocean temperatures. Slater says that the recent onset of glaciation in the Northern Hemisphere caused the evolution of gigantism in baleen whales. While the scenario for one of the last stages in the evolution of size of baleen whales is convincing, Olivier Lambert, a paleontologist from the Royal Belgian Institute of Natural Science, says that it was likely other factors such as the evolution of large predators and other climatic events which played a role in the development of the animals ' size.

As described in the documentary, “The whale just took a different approach to what it was going to do with a very senior, very experienced trainer, Ken Peters, and dragged him to the bottom of the pool and held him in the bottom, let him go, picked him up, took him down again.” This description allows the audience to know about the situation that the trainer went through. Also entails about the dangers that these marine animals as they’re trapped and trained can do to trainers. Another imagery described in the film was the incident involving Keltie. Keltie was performing with the whales when suddenly she tripped.

In the article “Evolution as Fact and Theory” Stephen Jay Gould who is one of the leading theorists in evolution argues that the debate between evolutionists and creationists is pointless since creationists’ arguments lack support and evidence. Gould writes that creationists’ main argument is that evolution is only a theory. However, Gould states that it is not only a theory but also a fact. He suggests that humans evolved from apelike— whether or not is happened by Darwin’s mechanism. What Gould is saying is that there is more than enough evidence to support the theory of evolution and the question that scientists are trying to answer is how exactly all living organisms are linked.

That makes this sources extremely dependable for my final paper due to all the good information it gives. This movie does a good job on the timeline of events. It starts in the beginning from where and how whales were captured to be put into sea-parks, and even follows the whales on their journeys. For example, the film mainly focuses on a giant whale named Tilikum and where he started, his events, where he moved, to and where he was last when the film was made. It also starts with the first sea-parks and how they grew into bigger ones.

Killer Whales: How they Physiologically Inhabit their Environment Introduction Despite its name, the killer whale (Orcinus Orca) is in fact a dolphin. It is the largest member of the dolphin family and one of the most successful predators of the sea. Due to their body structure they are able to move through the water with ease. They can control their body temperature which is essential for living in cold waters.

There is very few animals that would be able to eat what is left of the beluga whale but the nutrients still gets to them and it makes the water rich. Many creatures down here must survive of carcasses nutrients that falls from he surface and that is why it 's not a bad thing when beluga whales die from natural things. The fourth layer of ocean that the nutrients pas through is the Abyssopelagic Zone or other wise know as the "Abyssal Plain". Many physical parts of the beluga are gone but yet the nutrients are still falling down and its giving animals down there a rich environment to

BIOLOGY RESEARCH ESSAY There is great speculation around evolution. As we are continually in the process of discovering the history of human beings, there are many questions surrounding this topic. One very interesting question is why ancient ancestors of homo-sapiens evolved to walk upright like we do today. An apes’ DNA is astonishingly similar to that of a humans, (97% the same) and yet, our bones’ shapes and structure are very different.
