Identifying the molecular origins by which new morphological structures evolve is one of the
long-standing problems in evolutionary biology. To date, vanishingly few examples provide …

The cuticle of insects is decorated with non-sensory hairs called trichomes. A few Drosophila
species independently lost most of the dorso-lateral trichomes on first instar larvae. Genetic …

Transcriptional regulation plays a pivotal role in orchestrating the intricate genetic programs
governing embryonic development. The expression of developmental genes relies on the …

Quantitative variation in attributes such as color, texture, or stiffness dominates
morphological diversification. It results from combinations of alleles at many Mendelian loci …

Evolutionary analyses have estimated that∼ 60% of nucleotides in intergenic regions of the
Drosophila melanogaster genome are functionally relevant, suggesting that regulatory …

Species with temperature-dependent sex determination (TSD) exhibit significant variation in
the relationship between incubation temperatures and the sex ratios they produce, making …

Animal genomes are compartmentalized into insulated regulatory units named topology-
associated domains (TADs). TADs insulate gene promoters from enhancers that occupy …

Vertebrate Pattern Formation, Volume 159 in the Current Topics in Developmental Biology
series, highlights advances in the field, with this volume presenting interesting chapters on …
