Mating

Although there are many extinct animals, the Great Auk is an extraordinary animal. The Great Auk also had many variations in their egg’s, the streaks in their egg’s allowed the mating pair to recognize their egg at their breeding colony so they could determine the egg belonged to them. The Great Auk’s scientific name is also Pinguinus Impennis(“Great Auk”). The Great Auk’s habitat and geography. The Great Auk’s nesting colonies were settled upon rocky islands with sloping shorelines that…

result in copulation; males sometimes ignored the solicitation completely or inspected the genital area of the female and then lost interest (Ibid, 2004). Female choice among woolly monkeys positions the male to be the discriminating sex in their mating system. Another behavior associated with copulation is the so-called "tooth-chatter" or "click" where both female and male woolly monkeys retract their lips and open and close their mouth (Nishimura 1988; 2003). Females also use this type of…

1) Explain how the Lin et al. used the catFISH technique to determine which neurons are involved in particular behaviors (3 pts) Lin et al. used catFISH (cellular compartment analysis of temporal activity by fluorescent in situ hybridization) to compare the activation of c-fos expression during two successive episodes of behavior (either the same behavior or different) in the same animal. Through experimentation, researchers discovered that animals killed five minutes after fighting expressed…

stressors. Other differences in those two species of voles were seen after mating. Male prairie voles presented an increase in behaviors such as affiliation and mate guarding (Insel, 2010). These behaviors were not present in montane voles after mating occurred. This might suggest that the monogamous social organization in prairie vole is reflected through pair bonding right after mating. Knowing that AVP and OT are released during mating, it was proven that AVP, when centrally administered to…

The White Tailed Deer, otherwise known as the Odocoileus virginianus, is part of the Animalia kingdom, Chordata phylum, Mammalia class, Artiodactyla order, Cervidae family, and the Odocoileus genus. Odocoileus dervis from the greek noun odontis, which means tooth and from the Greek adjective koilos, which means hollow. Virginianus is a newer Latin term meaning “of Virginia,” which is used in taxonomy to indicate that a species is linked with Virginia and its surrounding areas. The O. virginianus…

study area then the biologist and his team make sonogram for each individual and they study song patterns of the mockingbirds. Later they find that syllables are affected by singing of other species of bird; for example: mockingbirds imitate other mating calls and incorporate other species’ songs into theirs. Mockingbird males that have more repertoires portray an advantage to gain territory rank because repertoire has a significant factor in determining the territory size that a male can…

Lizoabats are fairly large farquars with unknown origins. Some people believe that the Lizoabat is a relative of the dragon, but no researcher has made a successful attempt at capturing it to run test. This farquar has some special physiological traits, mating habits, and hunting techniques. Lizoabats are new to the animal kingdom. Little is known about such fascinating creatures, but this paper covers most of what has been…

What is mate choice? How did it evolve and why does it differ between sexes? To answer these questions, we first have to understand what it means to be female and what it means to be male under evolutionary standards and how the two sexes contribute to reproduction. Under biological terms, a female is the sex that produces the ova or egg, which is the larger sex gamete. The egg is large because it contains nutrients and material needed for the development of offspring as well as the DNA of the…

a psychological approach to distinct adaptive problems in relatively short term as opposed to the long term mating contexts. The authors insist that the social role theory looks at fertile assessment, sexual accessibility as well as assessment of mate value. All these contexts establish the roots under which the theory explains the gap between the two sides. It is universal that human mating has to occur and adolescent stage triggers the sexual desires. Authors insist that societies have…

Dr. Roughgarden’s talk discusses the evolution of gender and sexuality. She challenges Darwin’s Sexual Selection Theory which suggests that males are created with a higher sexual drive than females are. Along with this idea, Darwin implies that females are attracted to males whose appearance is, in simple terms, beautiful. Dr. Roughgarden disagrees with this and offers some examples as to why this theory is false. One of the examples that most interested me was her explanation of homosexuality…
