New genes and functional innovation in mammals
J. L. Villanueva-Canas, J. Ruiz-Orera, M. I. Agea…·M. M. Alba
The paper identifies mammalian-specific gene families and finds that new genes often originate from non-coding regions and are expressed in testis, suggesting a role for sexual selection in their evolution.
