Ne1 mezzo del cammin di nostra vita mi ritrovai per una selva oscura, che la diritta via era smarrita. Ahi quanto a dir qual era 2 cosa dura questa selvu selvaggia ed aspra e forte, che ne1 pensier rinnova la paura. DANTE PREFACE This book has grown, or better, exploded out of the Jesup Lectures that I gave at Columbia in 1969. Previous lecturers, in their(More)
There is presently a conflict between fossil- and molecular-based evolutionary time scales. Molecular approaches for dating the branches of the tree of life frequently lead to substantially deeper times of divergence than those inferred by paleontologists. The discrepancy between molecular and fossil estimates persists despite the booming growth of sequence(More)
The capacity to appreciate beauty is one of our species' most remarkable traits. Although knowledge about its neural correlates is growing, little is known about any gender-related differences. We have explored possible differences between men and women's neural correlates of aesthetic preference. We have used magnetoencephalography to record the brain(More)
Efforts to understand the genetic basis of evolutionary change have concentrated on proteins and their encoding DNA sequences. These studies have brought to light patterns and processes at the nucleotide level, yet the complex functional relationships between genetic variants and phenotypes remain poorly known. The realization that even a complete(More)
Echinococcosis is a worldwide zoonotic parasitic disease of humans and various herbivorous domestic animals (intermediate hosts) transmitted by the contact with wild and domestic carnivores (definitive hosts), mainly foxes and dogs. Recently, a vaccine was developed showing high levels of protection against one parasite haplotype (G1) of Echinococcus(More)
Lateral gene transfer (LGT) is a major evolutionary mechanism in prokaryotes. Knowledge about LGT--particularly, multicellular--eukaryotes has only recently started to accumulate. A widespread assumption sees the gene as the unit of LGT, largely because little is yet known about how LGT chances are affected by structural/functional features at the subgenic(More)
