Also, stabilizing selection is seen in these organisms by how each trait is balanced throughout the offspring of the organism.]]> 2018-06-04 03:03:25 UTC https://padlet.com/ab444/sgnyp2uv4v1x/wish/265277847 Evolution ab444 https://padlet.com/ab444/sgnyp2uv4v1x/wish/265279213
  • The type of speciation that occurred within this group is gradualism. These organisms haven't gone through short changes. They've seen evolution over a period of time, which represents gradual evolution
  • The type of evolution that occurred within these organisms is divergent evolution. Pinnipeds have evolved over time from a common ancestor which were land animals. These ancestors are described similar to bears and that they gradually adapted to living in water.
  • Nonrandom Mating -  Nonrandom mating occurs within pinnipeds because they look for specific characteristics when mating. Usually, the organisms will reproduce with one other specific organism.
  • Immigration & Emigration
    • - Some believe to migrate from France
    - Originated in cool, northern climates

    - Proteins, carbohydrates, lipids in common: squalene and transcriptome for making proteins 
    Embryology: 
    - Offspring have around the same time of development period]]>     2018-06-04 03:47:56 UTC https://padlet.com/ab444/sgnyp2uv4v1x/wish/265282412     Major Characteristics ab444 https://padlet.com/ab444/sgnyp2uv4v1x/wish/265765169 There are three types of pinnipeds including Otariidae (eared seals), Phocidae (earless seals), and Odobenidae (walruses).

    Otariidae:
    - Recognizable by their flippers and ears
    - Unlike earless seals, they have external ear flaps
    Phocidae:
    - Sometimes referred to as "true seals"
    - Have ear holes, no external ear flaps
    - Have front flippers to navigate on land, along with their stomachs
    - Move rear flippers back and forth like a fish to navigate in water
    Odobenidae: 
    - Have tusks and vacuum-like mouths for eating shellfish on the ocean floor
    - Air sacs in their neck to allow floatation
    - Largest pinnipeds


    External:
    - Pinnipeds have 4 webbed flippers for swimming, navigating on land
    - Spindle-shaped bodies
    - Large eyes, developed whiskers for filtering certain water
    - All pinnipeds have fur which occasionally sheds
    - Insulated by blubber

    Internal:
    - Since pinnipeds are carnivores, they have modified molars for consuming prey whole
    - Their sensory organs work in and out of water

    Behavior:
    - Carnivorous & predatory
    - Subject to predation by examples such as killer whales

    Habitat:
    - Present in habitats ranging anywhere from ice to tropics, or coastal to open waters]]>     2018-06-06 00:48:17 UTC https://padlet.com/ab444/sgnyp2uv4v1x/wish/265765169     Sources ab444 https://padlet.com/ab444/sgnyp2uv4v1x/wish/265767434 https://www.nationalgeographic.com/animals/mammals/l/leopard-seal/
