Wallace
27
It was called On the Origin of Species by Means of Nat-ural Selection
1859
28
The Darwin-Wallace theory of evolution: 1
Natural populations have the potential to increase rapidly (exponentially)
29
The Darwin-Wallace theory of evolution: 2
The resources to support these populations (food and habitat) are limited (carrying capacity)
30
The Darwin-Wallace theory of evolution: 3
Members of the population thus compete for these limiting resources
31
The Darwin-Wallace theory of evolution:4
Members of the population differ in inherited characteristics
32
The Darwin-Wallace theory of evolution: 5
Some are better adapted to the local environmental conditions
33
The Darwin-Wallace theory of evolution: 6
The best-adapted have higher survival and reproduction, and thus contribute more offspring to the next generation
34
The Darwin-Wallace theory of evolution; 7
Over time, the inherited characteristics that give higher survival and reproduc-tion will become more common in the population
35
The Darwin-Wallace theory of evolution; 8
Evolution thus occurs in populations, as they adapt to the environment due to differential survival and reproduction
36
The theory is called evolution by natural selection because it is __ ______ _________ that selects which members of the population will survive and reproduce
the natural environment
37
It is selection that affects mating success
sexual selection
38
members of one sex compete for mates
intrasexual selection
39
one sex chooses mates from amoung the opposite sex
intersexual selection
40
Individuals do not evolve; it is the ____ that evolves
popu-lation
41
Natural selection can only act on ____ traits (not acquired traits)
inher-ited
42
Since environmental conditions vary from place to place, a trait that is adap-tive in one location may ___ be adaptive in another location
not
43
Natural selection is not a creative process; it can only act on _____ _____
existing variation
44
Natural selection does not anticipate the future; it favors traits that are adaptive in the current, local environment, not in a ____ ________
future environment
45
what comes from teosinte plant from 1000 years ago?
maize (corn)
46

50
- began to swim by undulating the vertebral column up and down - The forelimbs became pectoral fins - The pelvis detached from the backbone and the hind limbs disappeared

51
_________ is the study of the geo-graphical distribution of species on Earth
Biogeography
52
He found that most of the birds on the islands were ___; how many species?
finches; 13
53
What Darwin observed in the finches on the Galápagos is an example of the ___ ____
founder effect
54
This is the establishment of a new population by a few individuals; After arriving on the islands, the founder finches had several habitats to themselves; The descendants of the immigrants competed not with other bird species, but among themselves
founder effect
55
The finch population adapted to variations in local conditions, including:
- Food sources (fruit, insects, cactus, seeds) | - Habitat (trees vs. the ground)
56
Period of evolutionary change in which groups of organisms form many new species whose adaptations allow them to fill different ecological roles in their communities
