Levels of genetic differentiation between populations can be highly variable across the
genome, with divergent selection contributing to such heterogeneous genomic divergence. For …

Reproductive isolation in plants occurs through multiple barriers that restrict gene flow between
populations, but their origins remain uncertain. Work in the past decade has shown that …

A recipe for dissolving incipient species into a continuum of phenotypes is to recombine their
genetic material. Therefore, students of speciation have become increasingly interested in …

We have sequenced the genome of a second Drosophila species, Drosophila pseudoobscura,
and compared this to the genome sequence of Drosophila melanogaster, a primary …

Historical and genetic evidences suggest that the recently founded population of Antioquia (Colombia)
is potentially useful for the genetic mapping of complex traits. This population was …

To evaluate sex-specific differences in gene flow between Native American populations from
South America and between those populations and recent immigrants to the New World, …

… selection in sympatry, then choosy females that preferentially mate with conspecifics in
sympatry may delay their mating with highly suitable conspecifics in allopatry (Ortiz-Barrientos …

… Current reciprocal transplant experiments in our laboratory (D. Ortiz-Barrientos, unpublished
data) suggest that extrinsic reproductive barriers are common in the system thus implying …

… To exclude this possibility, we measured the copulation latency and number of attempted
copulations by D. persimilis males towards D. pseudoobscura females derived from sympatry …

Similar traits and functions commonly evolve in nature. Here, we explore patterns of
replicated evolution across the plant kingdom and discuss the processes responsible for such …
