Female Crickets Calling Song Essay

Imagine living in a civilization that practiced human sacrifice and ritual dances, and then one day that civilization no longer exists because another culture decided to conquer them. These people are known to modern society as the Aztecs. In Graciela Limon's novel, Song of the Hummingbird, she illustrated how a culture like the Aztecs or Mexica, can quickly diminish when there are people such as the Spanish that have very limited understanding about certain subjects. Some people may say that the Aztecs were slaughtered because the Darwinian principle of natural selection even applies to mankind. This concept was perceptible when the Spaniards marched with horses, advanced technology, and armor. But through this novel,

Reproductive monogamy is defined as an exclusive sexual relationship between a female and a male based on their sexual interactions. Social Monogamy refers to male and female’s social living arrangement without sexual interactions. It refers to the living patterns, raising offsprings, and obtaining food. Monogamy is common in birds, but also occurs in invertebrates. Why would a male mammal choose to mate with one female when he can mate with more than one? Why would the male stay around instead of finding another female to live with? Many researchers have attempted to answer this question of why some mammals prefer monogamy over polygamy. Vole rats, one of the species that perform monogamous mating, demonstrate pair boding. Male and female pairs of vole rats have been observed together over several months, and the males stay with females even when the female is not reproductively active. A typical vole family in the wild is almost always consisted of one male, one female, and their offspring. In addition, unlike other species in which females are the only ones taking care of the offspring, vole rats share parental roles and even build nests together. Because they show these monogamous behaviors, they have served as a good species/model to learn about monogamy for neuroscientists. In this paper, monogamy, specifically in vole rats, will be explained along with its proximate and ultimate causes of this adaptation.

with people. In order to find her own "voice" in a society that is not

Mate choice is a product of mate preferences form in the environment of evolutionary adaptiveness (EEA). Sexual selection suggests that females prefer males who they can gain benefits from such as gifts. This is shown in male birds who make nests for females in order to mate with them and also in insects who give nuptial gifts.

In insect species with indirect sperm transfer, sperm is packed in a spermatophore that is either externally attached to the female 's genital opening or introduced into her bursa copulatrix. Sperm transfer is not immediate in these species, and consequently mate guarding has been suggested to function as a mechanism of guarding sperm until it is released from the spermatophore into the female (i.e. spermatophore guarding). Spermatophore guarding is relatively common in insect species with external spermatophores (e.g. Orthoptera; Alcock 1994; Simmons 2001), but supposedly absent in species with internal spermatophores and rapid sperm release (Simmons 2001). This study focuses on two hypothesis associated with mate guarding a tactic of many species that adjust their reproductive behaviour according to the apparent risk of sperm competition. The phenomenon of mate guard to consider sperm competition levels and evolution of internal spermatophore guard is wide spread in insects and other animals. We analyse two hypothesis one the rival exclusion followed by the next spermatophore renewal hypothesis. Results showed that as rival was introduced to the arena of mating of the distinctive original male (guard) in many cases showed a strong aggressive behaviour regardless of whether successively avert the rival. In the second hypothesis certainly majority of the incidents showed an attempt of

This essay aims to show a comparison between the differences between both female short-term mating strategies and female long-term mating strategies. It will explore the evolution of psychology that has shown reasons for human mating and how these reasons go above and beyond the general idea of physical attractiveness and love. This essay will identify how mate preferences have evolved and further identify psychological mechanisms that women have used to select their mates over the past. This essay will compare and critically discuss the differences and outline them between female short-term mating strategies and female long-term mating

The Novel “Song of a Humming Bird” by Graciela Limón is an outstanding novel that emphasis on an elderly Indian woman. Who is close to her death and is inclined to come to church for forgiveness for thy “sins” she has committed. This book is focused how Indian women lived back in the 50’s. It mentions two different opinions from an Indian and a Spaniard. I enjoyed this book a lot it gave me an inside of what happened back in the 50’s. I will be describing the difference between two main characters in the book, the challenges the main character faced (Huitzitzilin) through the whole book. As well the culture for both characters. I liked how the author (Graciela Limón) started current and then talked about the past while being in the

Predatory selection demonstrated heavily on how the predators prefered brighter males and how females then resorted to whatever was left. From my data of mostly drab and mostly bright guppies with the simulation having 30 rivulus, 30 acara, and 30 cichlids, I could see a clear trend. For the mostly drab guppies, in a mere 7 generations or 141 weeks, showed that the predators had wiped out the brighter guppies having a split demographic of 0% of the brightest and bright guppies, 30% for drab guppies and 70% for the drabbest of guppies. In the mostly bright guppy test, it was more even but showed an obvious lean towards the drabber guppies having 20% and 17% for brightest and bright guppies, and 17% and 46% for the drab and drabbest guppies respectively. With all this data, the trend leaned towards having the bright guppies

In each experiment , the pillbugs showed taxis. We observed how pillbugs incline toward dark and warm environments. There was a major distinction when the pill bugs picked between the dark and warm condition, 48 pill bugs went to the dark condition and 12 went to the light condition. By utilizing the chi-squared analysis, the calculated value ended up being 9.6 for the light and dark condition. This value was more prominent than the critical value of a 3.84. This implies the null hypothesis rejected in light of the fact that there is no contrast between these two conditions.When it came picking between the warm or cold condition there was a major distinction , 42 went to the cold condition and 18 went to the warm side. By utilizing the chi-squared

“The Grasshopper and the Bell Cricket”, a short story composed by the author Yasunari Kawabata, is a story written in the perspective of a person watching children looking for insects with their beautiful colored lanterns. Throughout the narration, we find a young boy named Fujio who supposedly caught a grasshopper(common), eventually turns out to be a bell cricket(unusual). Fujio starts calling out for for other kids to give his grasshopper to. Fujio keeps calling other kid to come, Fujio decided from the crowd a specific girl named Kijoko. As the story develops we can see how this two young souls are meant to be together as a coincidence or for a purpose in life.

Heterozygotes, which have the wild type phenotype, have normal sight which gives them the advantage of finding a mate and have a better success with attracting a mate with their courtship song (Kyriacou et al, 1978). The male heterozygous Drosophila had a better advantage at mating than the homozygotes, which were the ebony, and therefore we predict there will be more wild type by the end of the experiment.

Throughout her life, Marguerite experiences many different situations and people that all contribute to the way she grows up and the person she becomes. Despite some of her tragic circumstances, she learns a lot growing up, mainly because of the African-American women in her life who teach her all different life lessons. In I Know Why the Caged Bird Sings, Marguerite gets to absorb teachings from her mother (Vivian), Mrs. Bertha Flowers, and her grandmother (Momma). These women allow Marguerite to learn and grow as an African-American female, all while paving her own way.

Discussion The Effects of Total Body Length and Sex on Leg Length (n=48) In the experiment, it was shown that as the total body length of a cricket increases, the leg length of the cricket also increases in a linear fashion (Figure 1). As crickets grow in length, they need to use more force in its hindleg to jump a sufficient distance.

Another evolutionary explanation of gender development is mate choice, which suggests that gender role behaviours are related to reproductive strategies. It is thought that men will look for women who are young whereas women are usually more interested in the resources of a mate. This can be explained from an evolutionary perspective as mating with a physically attractive woman

The first few chapters discuss in depth both the general rules for mate selection and the differences in mate selection and varying preferences for male and female genders. As explained in the intro the author theorizes that the current behavior of humans in relation to mating behavior can be linked to our evolutionary past. He references Charles Darwin 's theory of evolution and his idea of natural selection, which is the the process through which organisms adapt to their environment and in doing so tend to
