Eusocial insects are highly organized and form __________. | colonies |
Eusocial insects are comprised of thousands of species of termites, ants, wasps, and some species of __________. | bees |
A non-scientific theory that was proposed to explain the complex social organization of eusocial insect colonies is __________ __________ theory. | intelligent design |
Intelligent design theory cannot be classified as scientific because its hypothesis is not __________. | testable |
Because intelligent design theory proposes a supernatural being as a creative force, the theory is considered __________. | religious |
Insect colonies contain few reproductive individuals. There is a queen, a few reproductive males called drones, and thousands of sterile female workers. The sterile females are considered to be __________ because they sacrifice their own reproductivity. | altruistic |
In performing protective functions for the colony such as stinging intruders or sealing the entrance to the colony at night, these individuals sacrifice their __________ for the good of the colony. | lives |
Sacrificial behavior, especially that of individual reproductive rights, constitutes a Darwinian __________. | puzzle |
Darwin reasoned that the puzzle of insect reproductive altruism could be solved if other family members passed on the traits. Darwin's thought was developed and modernized by a biologist know as William __________. | Hamilton |
The coefficient of relatedness between a man and his nephew is .25. This is because when a brother and sister has a child their own inherited genetic contribution from their parents is diluted by another __________ through marriage to their spouse. | one-half |
Fitness is reproductive success. Fitness refers to the number of __________ contributed to the next generation. | genes |
Fitness gained through personal reproduction was defined by Hamilton as __________ fitness. | direct |
Fitness gained by directly helping kin survive and reproduce is know as __________ fitness. | indirect |
The sum of direct fitness plus the fitness gained by helping kin reproduce who would not have been able to do so without this individual's help is know as __________ fitness. | inclusive |
Assume an individual has one offspring and also helps a sister to have three offspring. The value of the inclusive fitness measure is one point __________? | one point two five |
Hamilton's rule states that a trait can become more common if the indirect fitness gained by the non-reproductive altruist is __________ than the direct fitness lost by the self-sacrificing altruist. | greater |
Bees, wasps, and ants are referred by biologists as the __________. | Hymenoptera |
Hymenoptera have a unique chromosomal makeup. The full count of chromosomes for the species is possessed by female is referred to as the __________ number of chromosomes whereas the males possess only half that number of __________ value. | diploid ; haploid |
During sperm production, the chromosomes do not divide in the male, as they do in most species, hence all sperm are __________. | identical |
The father’s genes from his sperm contribute __________ percent of the daughter’s genes. | fifty |
The mother's egg also contribute fifty percent of her genes to the daughter, however, the similarity of those genes to the mother is only point __________ because 1/2 or 50% of her genes are randomly selected during egg production. | twenty-one |
The coefficient of relatedness between all females in a colony is more than one-half and actually point __________. | seventy-five |
Female workers bias their efforts towards the care of other _____ because females share 75% genetic similarity with their sisters and only 25% similarity with their brothers. | females |
Most studies find an investment ratio of __________ in favor of reproductively competent females across monogamous colonial species thus supporting the importance of monogamy and haplodiploid sex determination in the evolution of sterile worker castes. | three to one |
Another component of evolutionary theory besides natural selection is descent __________ __________. | with modification |
This notion embodies the concept that today’s living species are the product of __________ change in past species. | gradual |
Representations of possible evolutionary history in a species are known as __________. | phylogenic trees |
There are both polyandrous [multiple mates] and monogamous Hymenopterans. Phylogeny suggests the most likely base of eusociality is __________. | monogamous mating |
Sterile work forces dedicated to the care of reproductively competent females may be a byproduct of selection pressures related to __________. | disease |
The dance of the honey bee is one of the marvels of communication in the insect world. Information in the dance provides data on distance and __________ to the source of nectar. | angle |
32. If the honey bee performs a round dance, the food supply is within __________ meters | fifty |
The angular information in the dance is based upon the position of the food relative to the position of the __________. | sun |
A researcher by the name of Lindauer proposed that origin of the dance of the bees occurred possibly in __________ stages. | three |
In general, punitive control techniques suggest that the best way to boost inclusive fitness is __________ fitness. | indirect |
4. Intelligent design theory maintains that insect social behavior is the handiwork of a __________ __________. | superior being |
