Summary
Reconstructing the gene repertoire of the last eukaryotic common ancestor (LECA) is crucial for understanding eukaryotic cell origins. A community-driven approach is proposed to build a robust LECA gene set for evolutionary studies.
Area of Science:
- Evolutionary biology
- Genomics
- Cell biology
Background:
- The origin of eukaryotic cells (eukaryogenesis) remains a significant challenge in biology.
- Reconstructing the gene repertoire of the last eukaryotic common ancestor (LECA) is key to understanding early eukaryotic complexity.
Purpose of the Study:
- To summarize progress in understanding LECA biology.
- To outline a community approach for inferring LECA's gene repertoire.
- To establish a robust LECA gene set for hypothesis evaluation.
Main Methods:
- Genomic data analysis
- Community consensus building
- Comparative genomics
Main Results:
- Progress in understanding LECA biology has been made.
- A community approach for inferring LECA's gene repertoire is outlined.
- A robust LECA gene set will facilitate evolutionary studies.
Conclusions:
- A comprehensive LECA gene set is essential for resolving eukaryogenesis.
- This resource will aid in understanding trait evolution across eukaryotic lineages.
- The proposed approach supports diverse fields from medicine to agriculture.

The endosymbiont theory is the most widely accepted theory of eukaryotic evolution; however, its progression is still somewhat debated. According to the nucleus-first hypothesis, the ancestral prokaryote first evolved a membrane to enclose DNA and form the nucleus. Conversely, the mitochondria-first hypothesis suggests that the nucleus was formed after endosymbiosis of mitochondria.
Contrary to the endosymbiont theory, the eukaryote-first hypothesis proposes that the simpler prokaryotic and...

The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both...

01:21Three-Domain System of Life
Ribosomal RNA (rRNA) sequence analysis revealed three distinct groups of cells: eukaryotes, bacteria, and archaea. In 1978, Carl R. Woese proposed the concept of domains, a taxonomic level above kingdoms, to differentiate these groups. He suggested that archaea and bacteria, despite their similar appearance, represent separate domains. Domains differ in rRNA, membrane lipid structure, transfer RNA, and antibiotic sensitivity.In this classification, animals, plants, and fungi belong to the...

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.

Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.
