TLDR
The number of well-supported cases of transfer from both prokaryotes and eukaryotes, many with significant functional implications, is now expanding rapidly and major recent trends include the important role of HGT in adaptation to certain specialized niches and the highly variable impact of H GT in different lineages.
Abstract
Horizontal gene transfer (HGT; also known as lateral gene transfer) has had an important role in eukaryotic genome evolution, but its importance is often overshadowed by the greater prevalence and our more advanced understanding of gene transfer in prokaryotes. Recurrent endosymbioses and the generally poor sampling of most nuclear genes from diverse lineages have also complicated the search for transferred genes. Nevertheless, the number of well-supported cases of transfer from both prokaryotes and eukaryotes, many with significant functional implications, is now expanding rapidly. Major recent trends include the important role of HGT in adaptation to certain specialized niches and the highly variable impact of HGT in different lineages.

Introduction: protistan biology, horizontal gene transfer, and common descent uncover faulty logic in intelligent design.

TL;DR: This workshop focused on the acceptance of Darwinian evolution in the United States and the role of intelligent design (ID) in the ongoing controversy between scientific knowledge and popular belief.

Abiotic Gene Transfer: Rare or Rampant?

TL;DR: Conservative order-of-magnitude estimates are derived for rates of microorganisms subjected to freeze-and-thaw cycles, sand agitation, and lightning-triggered electroporation, at 1024, 1019, and 1017 per year, respectively.

Generalizable Learning: Practice Makes Perfect — But at What?

TL;DR: Practising a task can produce learning that generalizes to other tasks, but measurement of such generalization is complicated by how generalization doesn't always manifest simply as better performance on the new task, but also in the form of faster learning.

Emergence of heterogeneity and political organization in information exchange networks

TL;DR: The results indicate that such levels of organization arise generically as a collective effect from interacting agent dynamics and may have applications in a variety of systems including social insects and microbial communities.

The relationship between orthology, protein domain architecture and protein function

TL;DR: The 'domain grammar' hypothesis shows that the function of a protein follows from the domai grammar, and suggests that protein structure theory should be considered as a guide to protein function.

Lateral gene transfer and the nature of bacterial innovation

TL;DR: Unlike eukaryotes, which evolve principally through the modification of existing genetic information, bacteria have obtained a significant proportion of their genetic diversity through the acquisition of sequences from distantly related organisms.

Genome evolution in yeasts

TL;DR: Analysis of chromosome maps and genome redundancies reveal that the different yeast lineages have evolved through a marked interplay between several distinct molecular mechanisms, including tandem gene repeat formation, segmental duplication, a massive genome duplication and extensive gene loss.

Phylogenetic Classification and the Universal Tree

TL;DR: Molecular phylogeneticists will have failed to find the “true tree,” not because their methods are inadequate or because they have chosen the wrong genes, but because the history of life cannot properly be represented as a tree.
