essay代寫：哺乳動物滅絕的原因分析
侏儒的滅絕開始於大約5000年前。在過去的3000年裏，許多不能飛的鳥已經滅絕了。除此之外，許多來自遙遠太平洋上各個島嶼的帆船已經滅絕。這包括大約200種不同的脊椎動物。這包括海牛的滅絕，以及白令海峽島上存在的萊爾鷦鷯。由於太平洋大鼠的出現，新西蘭大量的地面築巢鳥類已經滅絕。
雖然在歷史時期也有過滅絕，但與近期的滅絕相比，這只是一個縮影。作者指出，近時間滅絕的證據發生在人類出現前後的時期，主要是偶發的(Haynes, 2005)。簡單地說，也可以說，當人類遍布不同的大陸時，許多原本是用來狩獵的動物滅絕了。
根據考古記載，世界上最早的人類是克洛維斯人。正是在這個時期，三分之二生活在美國的物種死亡。在這些國家中，最大的滅絕發生在墨西哥。其他瀕臨滅絕的國家包括墨西哥、中美洲和南美洲。寄生蟲和共生體在這段時間內死亡。據估計，大量的滅絕是由於對這些動物的過度捕獵、對它們生存的棲息地的破壞或引進了它們無法生存的這種疏遠的環境。
亞洲和非洲在最近一段時間內所遭受的同樣痛苦最少。這包括原始人和其他非洲野生動物之間存在的相互作用。由於世界的共同進化，人類的技能和許多物種的防禦技能都得到了提高。有時，隨著人類與動物建立起更緊密的關系，動物物種得以幸存。同樣的例子可以是對人類有利的駱駝和馬的使用。
此外，可以分析恐龍的滅絕與其他哺乳動物是不同的。恐龍在短時間內消失了，但哺乳動物卻逐漸消失了。氣候變化和人類活動被認為是地球上哺乳動物滅絕的主要原因。

The extinction of Dwarfs began around 5000 years ago. In the last 3000 years, a number of birds have been extinct which were unable to fly. In addition to this, a number of sails from various islands in remote pacific have become extinct. This includes around 200 different species related to vertebrates. This includes the extinction of Sea Cows and also the Lyall Wren who existed in the island of Bering Strait. A large number of ground nesting birds which used to exist in New Zealand were extinct because of the pacific rats.
Though there were extinctions in the Historical times as well, but that was in miniature in comparison to the near time extinctions. The author states that the evidence of near time extinctions which took place in the time period which was around the emergence of humans, majorly happened episodically (Haynes, 2005). Simply, it can also be stated that when the humans spread across different continents, a number of animals which were made for hunting, died out.
According to the archaeological record it can also be stated that the earliest human beings who had existed in the world were Clovis people. It was during this times, when two third of the species who existed in America died. Among these nations, the maximum extinction was faced by Mexico. The other nations which faced hugs extinction included Mexico, Central and Southern America. Parasites and Commensals were dead during this point of time. It can be assessed that a large number of extinction was because of over-hunting of these animals, the destruction of the habitat where they had existed or the introduction of such alienate environment which they were unable to survive.
The least suffering with respect to the same in the nearby time has been observed by Asia and Africa. This included the interactions which existed between the hominids and other African wildlife. Because of the coevolution of the world, there was enhancement of both the skills of humans and the defence skills of many species. Sometimes, Animal species survived as the humans established a closer relationship with them. The example of the same can be the use of camels and horses which were favourable for human beings.
Further, it can be analyzed that the extinction of dinosaurs is different from that of other mammals. Dinosaurs vanished in a small time period but mammals did gradually. Climate change and human activities are considered to be the primary reason for the extinction of mammals on earth.
