The Colonization of Land

The Colonization of Land

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...

Area of Science:

Evolutionary developmental biology (evo-devo)
Chordate evolution
Vertebrate origins

Context:

Evo-devo seeks to explain morphological evolution using developmental mechanisms and gene networks.
The origin of vertebrates from an invertebrate chordate ancestor is a central question in evo-devo.
Comparative genomics and novel model systems are advancing research in this field.

Purpose:

To review the features of amphioxus (Branchyostoma) as a model organism for studying chordate evolution.
To highlight the significance of amphioxus in understanding vertebrate origins.
To discuss the role of evo-devo in unraveling evolutionary history.

Summary:

Amphioxus (Branchyostoma) is presented as a valuable model organism in evolutionary developmental biology.
Its features are crucial for understanding the transition from invertebrate chordate ancestors to vertebrates.
Advancements in genomics and developmental analyses support the use of amphioxus in evolutionary studies.

Impact:

Facilitates a deeper understanding of vertebrate evolutionary history.
Provides insights into the genetic and developmental basis of major evolutionary transitions.
Supports the development of new research avenues in comparative genomics and evo-devo.
