Does dinner make a strong family, or does a strong family make dinner?
The family meal is often touted and encouraged for its social and health benefits, but a new Cornell University study questions the nature of this association, finding that the perceived benefits may not be as strong or as ...

Faithful females who choose good providers key to evolutionary shift to modern family, study finds
In early human evolution, when faithful females began to choose good providers as mates, pair-bonding replaced promiscuity, laying the foundation for the emergence of the institution of the modern family, a new study finds.

Change in developmental timing was crucial in the evolutionary shift from dinosaurs to birds: study
At first glance, it's hard to see how a common house sparrow and a Tyrannosaurus Rex might have anything in common. After all, one is a bird that weighs less than an ounce, and the other is a dinosaur that ...

Biology
Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy. Biology is a vast subject containing many subdivisions, topics, and disciplines. Among the most important topics are five unifying principles that can be said to be the fundamental axioms of modern biology:
Subdisciplines of biology are recognized on the basis of the scale at which organisms are studied and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions of systems of biological molecules; cellular biology examines the basic building block of all life, the cell; physiology examines the physical and chemical functions of the tissues, organs, and organ systems of an organism; and ecology examines how various organisms interact and associate with their environment.
