Some organisms have a long haploid phase, resulting in strong haploid purifying selection acting to maintain gene activity on the Y chromosome70,83,84. In species where haploid selection is more limited, many genes on the Y or W chromosome are sheltered in the diploid phase by the copy on ...
Boomerangs and throw sticks have been multipurpose tools for aborigines for thousands of years. Throw sticks are great for hunting creatures like emus and lizards. Boomerangs can be used for hunting small birds and bats but are considered more of a recreational tool for most people in the mode...

In order to stay in the air birds must weigh little yet be powerful. A bird's feathers enable it to fly. Feathers are light and flexible, but they are strong. Some larger birds like ostriches and emus cannot fly because they are heavy. Scientists who study birds are called ornithologists...
Draemus February 3, 2019 at 1:50 pm Just one question for you that I can’t find an answer to anywhere else for some reason; is it necessary to decarb your bud when making cannabutter since you need heat to make the butter in the first place? Would it not decarb at the same ...
“Very cool,” says Clifford Tabin, a developmental biologist at Harvard Medical School in Boston, Massachusetts. He thinks that Bhullar’s team makes a strong case that altered expression of FGF and Wnt shaped the bird's beak. Identifying the genetic changes responsible, however, will prove mu...
