美国俄亥俄大学论文代写:灵长类动物的性的研究

在包括人类在内的所有灵长类动物中,性与生殖的主要过程几乎是相同的,但灵长类动物的性可以研究如下。在这种情况下,女性的月经周期也很重要。灵长类动物的排卵过程是当雌性的卵子成熟时,会产生两个结果,这两个结果会触发雌性的荷尔蒙变化,从而使雌性感到被雄性所吸引。因此,它们向雄性发出交配信号,第二,它们的身体准备好接受雄性。在此期间发出的性信号是女性自动发出的,这些信号会刺激男性。

大多数动物通过嗅觉(基于嗅觉)可以感知到这一点,其他信号还包括生殖器区域的颜色变化、视觉信号、叫声或皮肤颜色的总体变化。这一时期,女性的变化被称为发情期(通常称为发情期)。其他时候,所有的活动都保持不变,除了没有卵子需要受精。然后雌性可能会和许多雄性交配,比如狒狒,或者一只雄性交配,比如长臂猿。在灵长类动物,几乎所有的动物,性活动和排卵的关系是一种自适应机制,以便有最大的机会繁殖不浪费精力和时间(Segerstrå勒,2000)。

The main course of sex and reproduction in almost same in all the primates including the humans, but sex in primates can be studied as follows. The female cycle is important in this case, too. The ovulation in primates is when the eggs in female mature has two results that is triggers the hormonal changes in females, which makes them feel attracted towards the males. And thus, they send signals towards the male for copulation, and second their body is prepared for being receptive to males. The sexual signals given out during this period are automatic by the females, and these stimulate the males.

Most of the species of animals can perceive this though their olfactory sense (based on smell), and other signals also include a colour change in the genital area, visual signs, calls or a general change in the skin colour. This period, when changes in female take place is known as in estrus (popularly, “in heat”). Other times, all the activities remain the same except that there is no egg to be fertilized. A female may then be involved with many males like in baboons or by a single male like in gibbons. In primates and almost all animals, the relation between the sexual activities and ovulation is an adaptive mechanism, so that there are maximum chances of reproduction without wasting energy and time (Segerstråle, 2000).
