TL;DR: This finding strongly suggests that the proliferation of the human ERV family HERV-K(HML2) has been almost entirely due to germ-line reinfection, rather than retrotransposition in cis or complementation in trans, and that an infectious pool of endogenous retroviruses has persisted within the primate lineage throughout the past 30 million years.

TL;DR: The developmental expression of AmphiPax2/5/8 indicates that the amphioxus central nervous system lacks a MHB resembling the vertebrate isthmic region.

TL;DR: Analysis of the evolution of 17 HERV families using d(N)/d(S) ratios finds a positive relationship between copy number and the use of additional copying mechanisms and discusses why these other mechanisms are rare in most families.

TL;DR: It is suggested that HERV-W processed pseudogenes arose by multiple and independent LINE-mediated retrotransposition of retroviral mRNA, and that the majority of HERv-W copies are actually nontranscribed promoterless Pseudogenes.

TL;DR: The present results on Alu and LINE stability/exclusion predict significant losses of Alu DNA from the GC-poor isochores during evolution, a phenomenon apparently due to negative selection against sequences that differ from the isochore composition.
