まとめ
パナマ で 発見 さ れ た 新 世界 の 猿 の 化石 は,熱帯 の 初期 の 霊長類 の 多様化 を 明らかに し て い ます. この発見は 南米と北米の間の哺乳類の交代に関する 最も古い化石の証拠です
科学分野:
- 古生物学
- 進化生物学
- 霊長類の進化
背景:
- 新世界猿 (プラティリン類) は新熱帯の生態系に不可欠ですが,その初期の進化の歴史は十分に理解されていません.
- 分子データは,パナマ半島が3-400万年前に形成された後,南米から中米に霊長類が散らばったことを示唆している.
- 中央アメリカにおける霊長類の化石の欠如は 新世界での起源の理解を妨げています

The Fossil Record
28.3K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

What is Evolutionary History?
44.6K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

Convergent Evolution
34.3K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Synteny and Evolution
4.0K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

Phylogeny
64.4K
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.
