Experiments that showed a surprising persistence of sexiness in worms reveal how much we are still learning about the rules governing heritability, epigenetics and natural selection. Playing the ...

For well over a century, Darwin's theory of natural selection has served as biology's grand unifying framework, explaining how species adapt and evolve through the differential reproduction of ...

Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA ...

Conflicts over parental investment are predicted to be common among family members, especially between parents and their offspring. Parent–offspring conflict has been studied in many brood-caring ...

Sexual reproduction allows organisms to mix up their genes and develop new adaptations to survive a harsh and ever-changing environment. Under nutrient-rich conditions, the worm C. elegans is ...

Introduction : how to write history of biology -- The place of biology in the sciences and its conceptual structure -- The changing intellectual milieu of biology Diversity of life. Macrotaxonomy, the ...

In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...
