Genetic drift
Random process
The key distinguished feature of a goof scientific theory
- Falsifiability
A crucial component of evolutionary theory missing from Darwin’s original formulation in the 19th century?
Mendelian genetics
consider skull size in human newborns- natural selections favor- phenotype in the population example of?
- Intermediate; stabilizing selection
Which statement best describes how fitness is measured by an evolutionary biologist? Fitness is measured by?
- Reproductive output of an individual in a population
Bones that support the wings of birds and bats are?
- homologous traits
The development of a hindlimb in 24-day dolphin embryo is best explained by?
- Adaptation environment
Darwin’s original contribution to biology?
none of the above
Which of the following is NOT a requirement for the evolution of A trait by natural selection?
Traits must make individuals stronger
Not consider atavism
- feathers on archaeopteryx
Basic unit of natural selection?
individuals
Fur color in a population of rat rangers from white to gray to black. Gray rats have a higher chance of surviving to reproductive age
- stabilizing selection
According to Cuvier the pattern of change in the fossil record suggested that
Wings of bats and wings of insects are- traits that are the products of- evolution
Analogous converted
Inferred by the chart on the right
- beak depth is variable and transmutable to the next generation
- The ultimate source of heritable variation in a population is
- mutation
The main driver of evolution after a severe bottleneck event?
genetic drift
Organisms with higher fitness in an animal that lives?
10 years and produces 100 offsprings
Darwin’s theory was threatened by the dominant 19th-century theory of- suggested that should increase over time
blending inheritance
A population that contains genetically and phenotypically identical organisms will experience
neither- evolution or natural selection
Consider a population that is not hardy-Weinberg equilibrium- in this population, we can determine- frequencies by measuring- frequencies-
Allele; genotype
Frequency of the A allele
0.50
frequency of the Aa genotype
0.50
What is the expected frequency of the Aa genotype under hardy Weinberg equilibrium
0.50
Consider a cross between heterozygous individuals and a homozygous recessive individual- out of 60 offspring the expected number of homozygous recessive is-
30
Artificial selection can sometimes result in the evolution of deleterious(maladaptive) traits
true
Archeopteryx is a transitional form between fish and amphibians
false
Darwin published “the origin of species” in the 1849
false
Natural selection=Evolution
false
natural selection-survival of the fittest
false
All genetic mutations are neutral with respect to natural selection
false
Structures that have no apparent function today but had a function in ancestral species are vestigial structures
true
Out of the three modes of selection that we learned about in class, stabilizing selection is the most likely mode of selection to drive speciation (the evolution of two species form one species)
false
