Phylogeny01:23

Phylogeny

47.2K
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.

The Colonization of Land

31.8K
Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

Non-vascular Seedless Plants

The diverse plant life on Earth—consisting of nearly 400,000 species—can be divided into three broad categories based on biological characteristics: nonvascular, seedless vascular, and seed plants.

What is Evolutionary History?02:35

What is Evolutionary History?

31.1K
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.

The Fossil Record02:56

The Fossil Record

23.0K
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...

Synteny and Evolution02:31

Synteny and Evolution

2.9K
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...

Summary

The discovery of a Late Triassic sauropod skeleton in Thailand provides the first bone evidence of these dinosaurs before the Jurassic period. This finding supports theories of early sauropod evolution during the Triassic.

Area of Science:

  • Paleontology
  • Vertebrate Paleontology
  • Dinosauria

Background:

  • Sauropods were dominant dinosaurs in the Jurassic and Cretaceous, but their evolutionary origins before these periods remain unclear.
  • Previously, the oldest sauropod evidence consisted of Early Jurassic bones and disputed Triassic footprints.
  • The early evolutionary history of sauropods is a significant gap in understanding dinosaur diversification.

Purpose of the Study:

  • To report the discovery of the earliest definitive sauropod skeletal remains.
  • To provide osteological evidence for sauropod existence during the Late Triassic.
  • To investigate the early evolution and diversification of sauropod dinosaurs.

Main Methods:

  • Excavation and analysis of fossilized skeletal remains.
  • Comparative anatomical study of the discovered sauropod fossils.
  • Stratigraphic dating of the fossil-bearing rock layers.

Main Results:

  • Discovery of an incomplete sauropod skeleton from the Late Triassic of Thailand.
  • The fossil represents the first osteological evidence of sauropods predating the Jurassic period.
  • The specimen exhibits distinct features differentiating it from known prosauropods.

Conclusions:

  • The Late Triassic sauropod discovery confirms a longer period of sauropod evolution during the Triassic.
  • This finding substantiates theoretical models of early sauropod diversification.
  • The unique anatomy of the specimen sheds light on early sauropod distinctiveness.
