进化论是一种科学理论,主要表明物种随时间而变化。物种变化有许多不同的方式,但大多数可以通过自然选择的概念来描述。通过自然选择进化的理论是第一个将时间变化的证据以及它如何发生的机制汇总在一起的科学理论。自古希腊哲学家的时代以来,特征从父母传给后代的想法一直存在。在18世纪中期,Carolus Linnaeus提出了他的分类命名系统,它将物种组合在一起,并暗示同一组内物种之间存在进化关系。 18世纪后期出现了物种随时间变化的第一个理论。像布冯公社和查尔斯达尔文的祖父伊拉斯谟达尔文这样的科学家都提出物种会随着时间而改变,但是没有人可以解释他们改变的方式或原因。由于当时的思想与公认的宗教观点相比存在争议,他们也将自己的想法保密。 Comte de Buffon的学生约翰·巴蒂斯特·拉马克(John Baptiste Lamarck)是第一个公开陈述物种随时间变化的物种。然而,他的部分理论是错误的。拉马克提议将获得的特征传递给后代。 Georges Cuvier能够证明理论的一部分不正确,但他也有证据表明曾经存在的物种已经进化并灭绝了。 Cuvier相信灾难,意味着这些变化和自然界的灭绝突然发生。詹姆斯赫顿和查尔斯莱尔反驳了库维尔关于均变论的观点。该理论认为变化缓慢发生并随着时间的推移而积累。有时被称为“适者生存”的自然选择是查尔斯达尔文在其着作“物种起源”一书中最为着名的解释。在这本书中,达尔文提出,具有最适合其环境特征的个体能够活得足够长,能够繁殖并将这些理想的特征传递给后代。如果一个人的特质不太好,他们就会死,而不会传递这些特征。随着时间的推移,只有该物种的“最适合”的特征存活下来。最终,经过足够的时间,这些小的改编将加起来创造新的物种。这些变化正是使我们成为人类的原因。达尔文当时并不是唯一提出这个想法的人。阿尔弗雷德·拉塞尔·华莱士也有证据,并在同一时间得出与达尔文相同的结论。他们合作了很短的时间,共同介绍了他们的发现。达尔文和华莱士因其各种旅行而得到了来自世界各地的证据,在科学界得到了关于他们的想法的有利回应。当达尔文出版他的书时,伙伴关系就结束了。通过自然选择进化论的一个非常重要的部分是对个体不能进化的理解;他们只能适应他们的环境。这些适应性随着时间的推移而增加,最终,整个物种已经从之前的状态发展而来。

英国伦敦大学论文代写:自然选择

Evolution is a scientific theory that mainly indicates that species change over time. There are many different ways of changing species, but most can be described by the concept of natural selection. The theory of evolution through natural selection is the first scientific theory that brings together evidence of time changes and how it occurs. Since the days of ancient Greek philosophers, the idea of ​​passing characters from parents to future generations has always existed. In the mid-18th century, Carolus Linnaeus proposed his classification naming system, which combines species and suggests an evolutionary relationship between species within the same group. The first theory of species change over time emerged in the late 18th century. Scientists like Buffon Commune and Charles Darwin’s grandfather Erasmus Darwin have suggested that species change over time, but no one can explain the way or cause of their change. Since the ideas at the time were controversial compared to the accepted religious views, they also kept their ideas secret. Comte de Buffon’s student John Baptiste Lamarck was the first to publicly state a species that changed over time. However, part of his theory is wrong. Lamarck proposes to pass the acquired features to future generations. Georges Cuvier can prove that part of the theory is incorrect, but he also has evidence that the species that existed have evolved and become extinct. Cuvier believes in disasters, which means that these changes and the extinction of nature suddenly occur. James Hutton and Charles Lyle refuted Kuul’s views on the theory of homomorphism. The theory states that changes occur slowly and accumulate over time. Sometimes the natural choice called “survival of the fittest” is Charles Darwin’s most famous interpretation of his book “The Origin of Species.” In this book, Darwin suggests that individuals with the best fit for their environmental characteristics can live long enough to reproduce and pass on these ideals to future generations. If a person’s traits are not very good, they will die without passing on these characteristics. Over time, only the “best fit” characteristics of the species survived. Ultimately, after enough time, these small adaptations will add up to create new species. These changes are what make us human. Darwin was not the only one who came up with this idea. Alfred Russell Wallace also had evidence and at the same time came to the same conclusion as Darwin. They worked together for a short time and introduced their findings together. Darwin and Wallace received evidence from all over the world for their various trips and received a favorable response from the scientific community about their ideas. When Darwin published his book, the partnership ended. A very important part of evolution through natural selection is the understanding that individuals cannot evolve; they can only adapt to their environment. These adaptations increase over time, and eventually, the entire species has evolved from its predecessor state.
