Proteins are the go-getters of a cell. They carry out all the jobs that are required for cells to grow, reproduce and perform other duties. But genes carry instructions for far more proteins than are present in a cell at ...

Among birds, the line between species is often blurry. Some closely related species interbreed where their ranges overlap, producing hybrid offspring that can even backcross with either parent species, until a whole population ...
