Physical characteristics (internal & external)
Domestic cows are large, sturdy animals. Weight ranges from 147 kilograms to 1363 kilograms, and height from 49-52 inches. The body is covered in short hair, the color of which varies from black through white, reddish brown, and brown. Domestic cows have short necks with dewlaps hanging below the chin. They have two hollow horns and a long tufted tail. They can be used as working animals for plowing and moving heavy loads. Domestic cows have no upper incisors, instead they have a thick layer called the dental pad. The jaws are designed for the circular grinding motion used to crush coarse vegetation.
Behavioral characteristics:
Cow herds are structured according to a dominance hierarchy. Each individual must yield to those above it in the hierarchy. Calves adopt their mother's status in the hierarchy. Females are often protective of their young and chase anything that threatens them. Females also share parental care within the group. Dominant males maintain this status until defeated by younger males in challenges.]]> 2016-06-01 15:27:34 UTC https://padlet.com/kaite792/lpwpztyo511h/wish/113344958 Dolphin Taxonomy kaite792 https://padlet.com/kaite792/lpwpztyo511h/wish/113345747 Common name: Bottlenose Dolphin

An example is if two animals have the same Kingdom, Phylum, Class, and Order these animals or organisms have evolved  from the same ancestor. If animals have evolved from the same ancestor this will allow them to have some of the same characteristics even if the organisms do not look a like. ]]> 2016-06-07 03:00:25 UTC https://padlet.com/kaite792/lpwpztyo511h/wish/113880554 Adaptive Radiation kaite792 https://padlet.com/kaite792/lpwpztyo511h/wish/113881059 There was adaptive radiation in extant Cetaceans when the oceans reconstructed. The animals went from terrestrial to aquatic mammals. When the oceans reconstructed the animals got separated and they went their separate ways which allowed them more room to live in the ocean.]]> 2016-06-07 03:09:46 UTC https://padlet.com/kaite792/lpwpztyo511h/wish/113881059 Type of Evolution & Speciation kaite792 https://padlet.com/kaite792/lpwpztyo511h/wish/113881123 Coevolution: Sharks and dolphins used coevolution two evolve with each other. They both have a streamlined body and one fin on the top of their bodies and two fins on their sides. They evolved to have the same body shape but they are very different on the inside. Sharks have skeletons made of cartilage but dolphins have skeletons made of bone. Sharks have gills to breathe in water. Yet, dolphins need to surface to breathe air. Sharks do not nurse their young but dolphins do.
Gradual Speciation: Change in this group occurs over a long period of time.]]> 2016-06-07 03:10:59 UTC https://padlet.com/kaite792/lpwpztyo511h/wish/113881123 Chromosomal Anaylsis kaite792 https://padlet.com/kaite792/lpwpztyo511h/wish/113881335 The karyotypes of dolphins (on the left) and humans (on the right) are very similar and that shows that they are closely related. The similarity is that they have the same amount of chromosomes and sex chromosomes. The difference is they have them spaced out in the human karyotype the top row has 5, the next row has 7, the next row has 6 and the next row has 5. In the dolphin karyotype the top row has 2, the next row has 9, the next row has 6, and the last row has 5.

They all travel in groups and get separated from others and start their own species. They also get separated by land masses such as the dolphins that live on the west and east coast. Geographic isolation causes these animals to develop differently for their environment. They can also cause them to go extinct because they will have less variation which could cause the whole population to wipe out if one thing went wrong.

Giraffes travel in small groups so they can get separated from the large group  and only breed with the same animals that they roam with. If the population of giraffes had been larger the animal would not be almost extinct it would only have a slight population decrease.]]> 2016-06-07 03:34:45 UTC https://padlet.com/kaite792/lpwpztyo511h/wish/113882077 kaite792 https://padlet.com/kaite792/lpwpztyo511h/wish/113882216 2016-06-07 03:37:40 UTC https://padlet.com/kaite792/lpwpztyo511h/wish/113882216 kaite792 https://padlet.com/kaite792/lpwpztyo511h/wish/113882254 2016-06-07 03:38:30 UTC https://padlet.com/kaite792/lpwpztyo511h/wish/113882254 kaite792 https://padlet.com/kaite792/lpwpztyo511h/wish/113882333 2016-06-07 03:40:06 UTC https://padlet.com/kaite792/lpwpztyo511h/wish/113882333 Phylogenetic Tree kaite792 https://padlet.com/kaite792/lpwpztyo511h/wish/113882846 This phylogenetic tree shows which organisms are closely related and also shows which organisms are further apart but are still in the same group.

Decent with modification is shown in my group through the adaptive radiation that occurred when Earth was evolving to allow animals to live in water and on land.
Stabilizing Selection occurs in my group especially in Giraffes because if a Giraffe is too short it will not be able to eat leaves but if the Giraffe is too tall all of the leaves in that area might be all gone.    ]]> 2016-06-07 03:52:45 UTC https://padlet.com/kaite792/lpwpztyo511h/wish/113882968 Anatomy  kaite792 https://padlet.com/kaite792/lpwpztyo511h/wish/113883312 Postorbital Bar- The number and size of teeth can vary but almost all canines and molars are absent or reduced except for the organisms that they turn into tusks.
Nasal Bones- The nasal bones in these organisms are not expanded which causes the organisms nose shape.
Paraxonic Limb Structure- The symmetry in the foot passes through the two middle digits. The thumb in most is absent causing the organism to have an even number of toes.
Large Bones- The animals in this taxonomic group have large bones which have been shown through fossils and they give the animals their unique structure.
