Geology 105 Final (College of Charleston)
QUESTIONS AND ANSWERS
1. By the stop of the cretaceous had been there many kinds of mammals? - ANSWER-No,
because dinosaurs ruled the preceding duration and when they went extinct, best
few types of mammals have been left.
2. Compare the two lineages of Miocene Apes represented through Sivapithecus and
Dryopithecus. - ANSWER-- New world monkeys: evolved first, small monkey
located first
- Old world monkeys: Don't have grasping tails, near nostrils
- Both determined in asia.
3. Describe a normal mesozoic mammal. - ANSWER-- Synapsid skull
- Different tooth sample
- Improved thermal law
- Hair
4. Describe an early horse with respect to legs, teeth, food regimen. - ANSWER-- Small
(dog size)
- four Toes
- Browser: low crowned
- Pointed teeth, U form jaw.
- Similar to trendy goat.
5. Describe some primary developments in horse evolution. Describe the modifications to
horse legs over the last 55 million years - ANSWER-- Teeth have become high
crowned
- Narrower, U shaped mouths
- Forest to grasslands
- longer legs with hoofs, reduction of digits
6. Describe the ancestor of primates - ANSWER-- Purgatorius
- Small tree residing animals, insect hunters, fruit eaters
- Lived in tree canopy
- Hands and toes for grasping
- Color imaginative and prescient
- Socialization complements mind capability
7. Describe the earliest known mammal, Morganucodon. When did it live? What turned into
the dimensions, morphology, and ecology of Morganucodont? - ANSWER-- very small
(4 in long)
- large brain / first rate senes
- Late triassic
- laid eggs
- hair
- enamel like mammals
, - jaw of a reptile
8. Describe the results of the meteorite impact on Earth's systems and how those
consequences could have brought about the mass extinction. - ANSWER-- Smoke from
meteorite precipitated a nuclear iciness
- months of global refrigeration, the sunlight become blocked.
- delayed greenhouse warming
- acid rain and wild fires.
- no photosynthesis, so plant life die = ecosystems die.
9. Different varieties of Whales - ANSWER-1) Pakicetus: four limbs, Earliest whale,
lived totally on land in swamp environments.
2) Ambulocetus:
- lives primary on land and in fresh water. Half/half of
- elongated head and frame
- hind limbs used as a fin
3) Dorudon:
- Deep water whale
- Direct ancestor to modern whales.
- lost hind limbs
- tail fin for propulsion
10.Discuss evolution of whales from land residing animals to aquatic animal. - ANSWER--
Echolocation : how they talk
- Through jaw bones, transmits sound through vibrations
11.Discuss the evolution of whale hearing. How do modern-day whales pay attention? -
ANSWER-- Echolocation is how they speak. Through jaw bones, transmits sound
through vibrations.
12.Discuss the physical evidence and the importance of an upright stance in Hominids -
ANSWER-- Evidence of Laetoli footprints of Australopithecus Afarensis
- Bipedalism: reduction of heat strain, strength green, higher imaginative and
prescient, unfastened palms
13.Discuss the steps within the transition from therapsid reptiles to mammals.
14.What were the most important innovations all through the transitions?
15.Be sure to consist of adjustments to the jaws/ears from reptiles to mammals. -
ANSWER-- more upright stance, in which the belly might be below the frame.
Canines, molars, and incisors showed exclusive enamel sample. Improved
thermal law. Hair in small therapsids.
16.Discuss the ones characteristics that mark the genus Homo. What makes our species a
predominate force on Earth? - ANSWER-- Brain capacity, lower in tooth and jaw size
- Large pelvis
- Long distance on foot and strolling
- Shorter intestine
- Social and cooperative searching, device making and loss of frame hair
17.Do New world monkeys or Old international monkeys more carefully resemble the
earliest hominids? - ANSWER-Old world monkeys resemble the earliest hominids
