105 QUESTIONS AND ANSWERS
1. Eleven.Where changed into the Wirst monkey found, and while did it stay? -
ANSWER-forty five million years in the past in Asia
2. Acheulean gear - ANSWER-Hand awl tools, sharper and extra particular for
hunting. Homo erectus
3. Anthropoidea - ANSWER-the suborder of primates such as monkeys, apes, and
people
4. are all species related to every different? Explain - ANSWER-Yes, consistent with the
idea of evolution, all species on Earth are related to each other, that means all of
them share a commonplace ancestor in some unspecified time in the future in
evolutionary records; this is frequently visualized as a "tree of lifestyles" where
each department represents a unique species, with the forks representing
common ancestors between them
5. Are birds dinosaurs? - ANSWER-YES, many functions of birds seemed particular to
them till this similarity became understood, many dinosaur fossils now show
proof of feathers and other fowl-like features
6. be able to describe the general characteristics of australopithecines, once they lived,
and their place within the evolution of animals - ANSWER--small brained herbivores
-3-4 MYA primitive
-bipedal-jap Africa
-effective chest and robust upper arms for mountain climbing
-upright body and a stride for taking walks (Lucy)
7. By the cease of the Cretaceous period, had been there many exceptional styles of
mammals? Please provide an explanation for - ANSWER-No, because dinosaurs
dominated the previous duration and when they went extinct, only few forms of
mammals had been left.
8. C3 and C4 grasses - ANSWER-C3 grasses had been softer and better for horses
residing in woodlands, C4 grasses have a better silica content, making it tougher
to bite so horses with harder teeth had been the only ones capable of eat it.
Grasses changed as the weather changed.
9. Charles Darwin - ANSWER-English herbal scientist who formulated a idea of
evolution by using natural choice (1809-1882)
10.Compare the enamel and mouth of early horses with Equus. - ANSWER-Early horses
teeth had been low-topped & they had a U-formed muzzle (the browser in the
woodland)
Equus (modern) horse enamel are high-topped, & have a excessive, linear muzzle
(the grazer on grasslands)
11.Compare the two lineages of Miocene Apes represented by Sivapithecus and
Dryopithecus. - ANSWER-Both dryopithecus and sivapithecus lineages are rooted
, in Europe, however Dryopithecus migrated to Africa and Sivapithecus migrated to
Asia. Dryopithecus cranium resembles that of a juvenile chimpanzee, and they're
ancestor to African apes and human beings. Both ate culmination and nuts. The
simplest living descendant of the Sivapithecus lineage is the orangutan.
12.Contrast the lifestyle and device making of Neanderthals with H. Sapiens. -
ANSWER-Neanderthal tool making became less complex than H sapiens
Humans have superior device making, specialization and trade
Humans had symbolic abstraction cave painting- art and studying. Neanderthals
did as properly however it turned into less complicated
13.Contrast the notions of ecological substitute and displacement. Did mammals
out-compete the dinosaurs? - ANSWER-Ecological replacement- filling open niches
after the extinction
No, they changed open niches and adapted to the surroundings.
14.Descent with amendment - ANSWER-principle that every dwelling species has
descended, with changes, from other species over the years
15.Describe a normal Mesozoic mammal. (size, life-style, ....) - ANSWER-Synapsid Skull
Different Tooth Pattern
Improved Thermal Regulation
Hair/fur
16.Describe Ambulocetus. What is its significance? - ANSWER-its skeletal structure
indicates it may likely walk on land whilst also swimming proficiently in water,
supplying key proof for how whales developed from terrestrial ancestors
17.Describe early first horses like Sifrhippus. - ANSWER-Very small (12 lbs)
Browser- low crown enamel
Narrow, U-fashioned muzzle
Shrank through the years making adults 8 lbs versus 12 lbs after which after
PETM became bigger once more as much as about 15 lbs
18.Describe Morganucodon, one of the earliest regarded mammals. When did it live? What
had been its size, morphology, and ecology? - ANSWER--very small (four in long)
- big brain
Late triassic-
laid eggs
- hair
- tooth like mammals
- jaw of a reptile
19.Describe Pakicetus. What is its significance? - ANSWER-it affords proof of the early
levels of whale evolution, showcasing how land-residing creatures step by step
tailored to an aquatic lifestyle
20.Describe the adjustments to horses' legs over the last fifty five million years of evolution.
- ANSWER-Only 1 toe in keeping with foot and long legs
Went from many bones to 1 leg and 1 toe
21.Describe the outcomes of the meteorite effect on Earth's systems and the way these
effects might have brought about the mass extinction. - ANSWER-Global refrigeration
Acid rain
