This second line of fossil evidence for evolution is no less controversial than the first. For example, consider the ostensive evolution of the horse as described above, undoubtedly the single most popular and widely known sequence of transitional fossils. Critics point out that the fossils used to create the hyracotherium-to-horse sequence are found on opposite sides of the planet, oceans apart. This geographical discontinuity is an obstacle for advocates of the sequence. Those fossils which actually do appear on the same side of the ocean cause some difficulties as well. A species of three-toed horses were found together with a species of single-toed horses in the same rock formation in Nebraska, indicating that they lived side-by-side. As for the fossils’ progressive increase in size, this is a mute point. Modern horses vary greatly in size, from small dog-sized miniatures to massive Belgians, Clydesdales, and Percherons.
Due to the peculiarities of any argumentative essay, its thesis statement may be considered one of its vital parts. A proper and correctly built thesis statement can make the reader strongly interested in the author’s arguments presented in it. Correspondingly, the thesis statement of any argumentative essay should be very clear and present not only the argument of the author of the essay but also the reasons this argument is true. Therefore the argument itself needs to be as narrowed as possible being related to the topic of the essay. Another important element of the argumentative essay thesis statements is that it needs to be as objective as possible revealing the academic approach of the author. In other words the argumentative essay thesis statement presents the main arguments the author uses to support this notion the author is focused on. All the words need to be thoroughly chosen and used.
When you make your assertion in your thesis, it should be clear and direct. You want your audience to have no doubt about your point. Of course, how assertive you are in your thesis and the content you choose to include depends upon the type of argumentative essay you are writing. For example, in a Classical or Aristotelian argument (explained in pages that follow), your thesis statement should clearly present your side of the issue. In a Rogerian argument (explained in pages that follow), your thesis should bring both sides of the issue together.
