  1. Okay, This is cow evolution by Britney and medals.
  2. The scientific name for cows is the boss Tourists.
  3. Now these animals have common ancestors that they descended from
  4. including Rx which were wild ox, that wrong in Europe.
  5. In Asia they're the most recent ancestor of cows.
  6. They were the first recorded animal to have gone extinct
  7. in 16 27 and they're larger than modern cattle.
  8. Next we have boss, which had hopes with an even
  9. number of toes.
  10. They were grazers, they had large teeth and they had
  11. a life span of about 18 to 25 years.
  12. Next we had the Unga Lotte, which were a transitional
  13. species. They had moved the large horns and they were
  14. grazers as well.
  15. Next we have the Miocene antelopes which led to the
  16. boat today.
  17. Species? They were Martin.
  18. They marked the appearance of over day and they may
  19. be a sister ancestor.
  20. Next are the boat today, which I found in all
  21. parts of the globe.
  22. Except for South America and Australia, they had cloven, they
  23. were cloven hooved and they were ruminant mammals.
  24. Finally, we have the serve a day which are part
  25. of the dear family.
  26. Their sister ancestor.
  27. They're related by the Rto deck, Tila and they have
  28. even tow hooks.
  29. Next, we have our fossil evidence.
  30. Uh, this picture shows a transitional fossil in the cow
  31. species. The 1st 1 was probably in for rock, and
  32. then the next one was an angle.
  33. Lotte on the final one was the transition to the
  34. modern cow.
  35. Um, this timeline shows when our cows first became domesticated,
  36. which was about 10,000 years ago, they were first domesticated
  37. in India in the Middle East.
  38. And this is when modern cows began to show their
  39. changes. Adaptations of these animals where their primary food were,
  40. Hey, silage and grass.
  41. The species lived in grasslands.
  42. Their predators were coyotes, Cougars, bobcats, lynx, dogs, wolves, vultures
  43. and bears.
  44. Usually they interact with the same species and grazing herds
  45. to protect from or avoid predation.
  46. Our file Odin a tree shows the transition in the
  47. modern cows.
  48. Um, and it also shows buffalo and Zebo being the
  49. most related species to cows.
  50. Our evidence of natural selection is in the angle of
  51. the cows.
  52. Horns being shifted upwards.
  53. The smell of the cow became shorter.
  54. Cows became much smaller compared to or ox, and longhorn
  55. cattle underwent natural selection when becoming domesticated.
  56. They became wild, the semi wild, and that's our presentation.
