Survival of the Fittest

About Me:
My name is Emily Wright. Iam a student at Olathe North Highschool.I am on the drill team at my school and it is a great life lesson for me and helps me to stay on top of my gread and pretty much just love to dance. I hope to to do welll in school and hopefully graduteand go to a great college. When I grow up and get out of college i hope major in a health or science career and hopfuly have a great job that not only pays good but i will enjoy it to.

Survival of the Fittest
All animals live in there own habitats. Habitats provide them with food, water, and shelter which animals need to survive in the wild, but there is more to survival than just their habitat. Animals also depend on their physical features to help them obtain food, keep safe, build homes, withstand weather, and attract mates. These physical features are called physical adaptations. Physical adaptations do not develop during an animal's life but over many generations. The shape of a bird's beak, the number of fingers, color of the fur, the thickness or thinness of the fur, the shape of the nose and or ears are all examples of physical adaptations which help different animals survive in the wild.
Now to be the “fittest” the animal has to have the best adaptation in order to win the game. Some examples of survival of the fittest are wild cats, such as panthers and cheetahs. To me they are the perfect fit to the topic of survival of the fittest.
They all have long legs, short faces, and athletic bodies with beautiful fur. In addition, they can all retract their claws, have a developed sense of smell, and they all purr. With the exception of the lion, all the felines are solitary hunters, kill rather small prey, and usually hunt at night. Interestingly, the lion is the most social of the felines, and lives and hunts in a family group which we call a "pride".
There are thirty or so species of cats on this earth “It is now thought that because cats have always roamed, and that in prehistoric time, it was possible to cross land bridges to roam all the continents freely, which is difficult for us to imagine today in everyday life”.
To me one of the main reasons that wild cats are the fittest is there diets. Fresh meat killed by their mother or themselves is the only item on the cat’s diet, which means that their survival for them is no easy matter. Their food is not found on trees, waiting to be eaten or on trees. Nature has supplied the cat with the intelligence, courage, and speed to become and to stay the amazing hunters that it needs to be to survive in the wild. Hunting is a main part of the wildcat’s life. When one observes young kittens playing, you may notice that they look like they are fighting, but in reality they are learning to hunt without being in any real danger. The process of hunting means more than just food to the wild cats but more like the victory of the hunt, because a cat can hunt without eating, but cannot eat without hunting.
• There color of there fur helps them blend into there surrounding, in which helps them not only hide but catch there pray.
• There speed is another great adaptation, their powerful hind legs also help them catch their pray.
• They also hunt in packs which help them to keep a watch out for each other, and also helping them catch enough pray to feed the entire group.
• They live in large groups for there protection and there convenience.
Cats are said to be one of the most evolved animals with there many different territories and different looks. They all have kept up with the world in such a tremendous way. Starting out as two different species Neofelines, which are the sabre tooth, and the Palaeofelines, which are Dirk tooth. And then spreading there horizon too many different breeds of the tiger or a lion is amazing. All equally powerful in there own way.

humans involvement with selective breeding

About Me
Samantha Zakaras
I am an Olathe North student in Student Naturalist, and I'd like to show you mankind's involvement with selective breeding.

Selective breeding in domesticated animals is the process of a breeder developing a cultivated breed over time, and selecting qualities within individuals of the breed that will be best to pass on to the next generation.
Humans use selective breeding to improve a specific species to help the human race, like improving chickens body mass for more meet or to enlarge the eggs for more to eat. We also improve cows production of milk.


But the selective breeding can cause the chickens legs to be unable to grow as rapidly as its body, causing it to be limp. Isn't that cruelty?

These People selectively bred these chickens to be featherless so they wouldn't have to worry about the heat in the sheds as much.

As man keeps doing more research and testing our biotechnologists and life scientists keep making food better for us. And we have more jobs for scientists. But is this really better for us or are we effecting mankind too? Some will argue that we are striping religon from sociaty and teaching the wrong things to our children, but are we?

Also purebred animals are apart of selective breeding.
Purebreds, also called pure breeds, are cultivated varieties or cultivars of an animal species, achieved through the process of selective breeding. When the lineage of a purebred animal is recorded, that animal is said to be pedigreed.
But purebred is not Thoroughbred, which refers exclusively to a specific breed of horse.
