adaption

62
Q

_____________ was born in 1809
-The prevailing ideas at the time did not include evolution:
1.
2.

A

Charles Darwin

  1. they believed the earth was young
  2. they believe species that inhabited the earth were believed to be unrelated and unchanging
63
Q

In 1809, _______________ became an early proponent of evolution

A

Jean Baptiste Lamark

64
Q

Lemark suggested a mechanism to explain how organisms change and how evolution occurs

  • Body parts that are used to explain how organisms lifetime become larger and stronger and these modifications are passed on to the organisms and offspring
  • although not support genetically he deserve credit for first oppose to traditional ideas
A

Jean Baptiste Lamark

65
Q

Charles Darwin was a naturalist on the _____________ from 1832-1836.
An around the world voyage

A

beagle

66
Q

Darwin visited

A
  • south america

- a visit to the galapagos islands proved extremely influential

67
Q

Darwin notices

Darwins finches

A
  • simularities among the species he encountered but also many differences
  • species were well adapted to their environment
68
Q

species diversity appears to be a result of

A

environmental diversity

69
Q

durage his voyage, darwin read _______________

A

Principles of Geology

70
Q

Lyles proposed that

A

the earth that is much older than 6,000 years and was sculpted by timely processes

71
Q

_________________ shared his evolution discoveries with Darwin and they agreed

A

Russel Wallace

72
Q

darwin published his book ______________. In his book, darwin used the phrase ___________________________ to describe evolution

A

the origin of species by means of natural selection.

descent by modification

73
Q

all species are descended from there ancestors but

A

they are modified by their ancestors

74
Q

Darwin argued that

A

adaption to environment and the origin of near species are related

75

Q

_____________________ refers to the comparison among species of body structures that are present ONLY EARLY DURING DEVELOPMENT

comparative embryology

83
Q

closely related species have DnA that has very similar

A

nucleotide sequences

few differences have accumulated because related species have spent a relatively short amount of time diverging from a recent common ancestor

Q

two observation for natural selection

limited resources lead to __________ among offspring

natural selection
