In our recent paper we found alleles at six genes, introgressed from dogs to Iberian wolves thousands of years ago, that were positively selected for. Half associated with the #immunesystem . The others could impact #behavior
Also, despite massive reductions in wolf population and lots of dogs, there has been very little introgression.

In a first, evolutionary biologists have identified a gene that influences visual preferences in tropical #butterflies

"We've known for quite a while that the red color pattern gene was introduced from one species to the other through #hybridization, and suspected that the same might be true for the corresponding preference. To finally show it, and identify the specific gene is really exciting"
Tropical Heliconius butterflies are well known for the bright color patterns on their wings. These striking color patterns not only scare off predators—the butterflies are poisonous and are distasteful to birds—but are also important signals during mate selection.
The most interesting in a selective sweep is the shoulders.
