Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2019
AbstractIn the past, most biologists, myself included, did not think of evolution as changing over time. The wonders of natural selection were always at hand and went into operation once there was life. However, with a little reflection it becomes obvious that evolution has changed—there has been an evolution of evolution.

Trends in Ecology & Evolution, 2001
Two recent studies have cast new light on the evolutionary history of MYCORRHIZAE. New fossil evidence has pushed the date for the appearance of ARBUSCULAR MYCORRHIZAE back to 460 million years ago, predating vascular plants. A phylogenetic tree for the Basidiomycota shows that these fungi have gained (and lost) the ectomycorrhizal condition repeatedly

ENHANCING EVOLUTION AND ENHANCING EVOLUTION
Bioethics, 2010ABSTRACTIt has been claimed in several places that the new genetic technologies allow humanity to achieve in a generation or two what might take natural selection hundreds of millennia in respect of the elimination of certain diseases and an increase in traits such as intelligence.

WIREs Cognitive Science, 2016
Biologists and psychologists are re‐thinking the long‐standing premise of genes as the primary cause of development, a view widely embraced in 20th‐century biology. This shift in thinking is based in large part on: (1) the growing appreciation of the complex, distributed regulatory dynamics of gene expression; and (2) the growing appreciation of the ...

RAIN, 1979
AbstractThe common ancestor of modern humans and the great apes is estimated to have lived between 5 and 8 Myrs ago, but the earliest evidence in the human, or hominid, fossil record is Ardipithecus ramidus, from a 4.5 Myr Ethiopian site. This genus was succeeded by Australopithecus, within which four species are presently recognised.

Polymerase evolution and organism evolution
Current Opinion in Genetics & Development, 1992The continuing exploration of the structure-function relationships of polymerases and the use of polymerases as phylogenetic tools complement each other, as seen in the literature for the past year. DNA-dependent RNA-polymerase gene sequences, in particular, have been used both to define functional domains in the protein encoded and recently to explore

Plant Evolution: De-evolution and re-evolution of maize
Current Biology, 1994Studies of the genetic differences between maize and its wild predecessor have started to reveal genes responsible for evolutionary innovations.

Nature Biotechnology, 2019
The combination of modern biotechnologies such as DNA synthesis, λ red recombineering, CRISPR-based editing and next-generation high-throughput sequencing increasingly enables precise manipulation of genes and genomes. Beyond rational design, these technologies also enable the targeted, and potentially continuous, introduction of multiple mutations ...
