Transcript of Scientific Gazette
man for making discoveries that no other scientist
could have imagined. In 1831, December, Darwin set sail on
his ship the Beagle, leaving his funding country, England. He was 22 at the time,
and he wanted to become a naturalist. He
took notes on important things. Darwin sailed across the world,
but his most frecuent stops
where in South America. His first stop was at St. Jargo. He was born in England on 12 February 1809. At his time, people thought new species were made from god.
Darwin looked at many animals
and studied them He noticed that the fossils he found were all bigger than the actual animal. One of his most
amazing one was at Punta Alta in Patagonia, he found fossil bones of huge extinct mammals on the cliffs beside the shore, and it pointed out recent extinction with no signs of change in climate or land. He later knew that little known fossil was the same as an armadillo, except bigger, by comparing them with the same size of teeth. His visit across the
globe made him prove his
theory- it was natural selection Darwin's Voyages Darwin was fascinated by animals and wanted to study
them. He went around the world, but he stopped
mostly at South America. He also compared the Galapagos Island animals
with South America animals. He realized that there
was not much difference. This meant the South
America animals might have went to the Galapagos
Islands and adapted. When he was not studing animals, he
would study his finches that he collected.
On the Galapagos Islands, he found
that each island had a different type
of finches, some with bigger beaks,
and some with short beaks. Darwin named it adaptation. The birds
came from one ancestor, but over time
their beaks changed so it could suit them
in their environment. He also noticed most old fossils were water
adapted. Most of them were still moist, or softer
than usuall. Darwin concluded that the
world was once underwater,
but everyone adapted to their
enviroment. So through his studies he found out that all
animals and humans came from one ancestor.
However, not many people agreed, and there
where many fights about this. Today we
know Darwin was right all along. Fin. Darwin then concluded that everyone came
from one ancestor. Hoever, not many people
agreed, and there were fights. We now know
he was right all along. Made by Ameen Saleminik.

His dad was a doctor, and a famous one to. He
served rich people. He sent Darwin to medical
school. Darwn did not focus in medical school, so his parents sent his to priest school. He dropped out of that and was invited to go sailing around the world. He was a geologist, and loved studying rocks Natural slection and how it works Darwin made a book called the Oringin of Species by Natrural Selection. He thought evelution occured through natural selection.
What is natural slection? Natrual selection is when there are induviduals that have traits that make them so the are more likely to survive than others. When they have children, then the children get those traits and also survive. Darwin had read an essay called Essay
On the Principles of Population. In it the author wrote that organisms tesnd to have a lot of offspring. This is called overpopulation. However. Darwin knew why insects are not invading the earth. Variation was the answer. For example, the reason insects dont eat all the Earth's
food is because not all insects eat the same thing. Certian insects eat plants, while others dont. Because food is limited, there is often
compitition. It isn't always physical fights, in fact mostly it is indirect. When the organisms cannot find food, they die, or a predator eats them. Only few survive. Selection is when the induviduals that
have offspring pass down those traits,
and the children have those traits and it keeps on being passed down. This is sucssesful reproduction. enviromental Factors however can change the way things are. Lets say some flowers can't grow near a gold mine. But over the years, they have adapted to survive it. These are all part of natural
selection. One example are turtles. When they are born, they have to struggle and get into the ocean. Many die in the frenzy. When the turtle grows up, there is compitition for the food. Only the selected trutles with the good traits will survive, then have babies with the same traits. That is all looped together with natural selection. Evidence For Evolution There are many things that make up evidence for evolution. Here they are:
DNA evidence The fossil record is preserved parts of a animal that had lived in the past. The millions of fossils found make up the fossil record. An example of a fossil is down bellow. The fossils help determine what
animals looked like back then, and
if they were the same to today's animals
Vestigal structures are just things that the organism has but doesn't use any more. Lets say we had a snake. That snake has a pelvis and a femur. This means that the ancestor of the snake used to walk. This helps scientists see what the traits and things that helped them back then, but no so much now. Homologous structures are when there are similiar structures in species. The dog, dolpihin, and even bird all have similair bone structures. This means they evolved from one ancestor. This supports the idea for evelution because they evolved into different things. Embryos are early satges
of life. Here is a very funny example. Here is a real example. That shows we were that creature at beggining birth to what we are today. Thank you you for reading this. All

by Ameen Saleminik No wait! There are comics! Letter to the editor
The evolution theory was a pretty wild guess for Darwin. If it wasn’t for him, we would have not known how we were here. It was a nice time typing up the facts, and I was learning at the same time! I never knew how we came to be human and who guessed it. I would of said that myself. Darwin was a daring person. I hope the person who read the Scientific Gazette would say the same thing. When I was in 7th grade they said that there is just us humans and God made us. I was surprised to do this article. Thank you for reading it.
