b) Humans did not have time to train the wolves.
c) The wolves would have eaten too much of the humans' food.
d) Early humans would not have been able to selectively breed wolves. - Answer-Early

Silver Fox Experiment - Answer-Only six generations of artificial selection for tameness
produced domestication traits such as curly tail, white spots, and floppy ears
Domestication Syndrome - Answer-A suite of traits that consistently appear together as
a by-product of the selection for tameness, such as floppy ears, curly tails, smaller
brains, teeth and muzzles, and white fur patches and behavior such as licking, and
responsiveness to human social cues.
Cross-Fostering Experiments - Answer-Demonstrated that neither the prenatal uterine
environment nor postnatal rearing significantly altered the genetically bred temperament
of the kit foxes.
Pedigree Dog - Answer-Dogs with such highly specialized abilities, produced by careful
breeding and even inbreeding, and guaranteed by the American Kennel Club (AKC).
Neural Crest Cells - Answer-Cells that during development migrate to different parts of
the body where they contribute to the development of local tissue types (e.g., adrenal
glands, melanocytes, cartilage)
Fitness differences - Answer-Members of a population vary in traits that lead to
differences in survival and reproduction.
,Who developed the idea of Evolution by Natural Selection?
a) Darwin and Wallace
b) Darwin's grandfather Erasmus Darwin
