Wolf Ethology
38 Living Species
of Dogs.
Of the 39 KNOWN species,
only one is extinct, The
Falkland Islands Wolf.
Dogs of one type or
another inhabit
almost every part of
the Earth. Except
Antarctica and some
remote islands.
Biological Evolution;
the process of change
and diversification of
living things over time.
Variations in hereditary
can occur in two ways;
spontaneous mutation,
in which variants
change from one to
another, or the sexual
process, in which
variants combine to
form many variations.
Mutation; basic,
significant, relatively
permanent change in the
genetic makeup of an
organism.
Variations
that
are
a
random
act
of
chance
are
termed
Genetic
Drift
Natural Selection
Process is then followed by Natural Selection of these variants that are most effectively passed on to Future generations.
This theory argues that the tremendous amount of Genetic Diversity is brought upon by Natural Selection.
Charles Darwin Based this theory on the existence of hereditary variation.
As successful species multiply, unsuccessful Species dwindle in number.
Results in species that are more adapted to a given environment.
Factors affect the number of offspring an organism is able to produce and include differences in survival, fertility, rate of development, or mating success.
Humans ability to develop different varieties of plants and animals, so must these varieties occur in nature.
Humans began to breed dogs that retained puppy like behaviors.
Neoteny; the retention of puppy like behaviors or Characteristics.
Barking; a distinguished characteristic between domesticated dogs and wild dogs.
Chasing prey but not going in for the kill.
Submission to a greater power. In dogs case, to humans, and not a dominant member of a pack.
The classification of organisms into different categories based on their individual physical, genetic, and biochemical relationships to one another.
