Evolutionary developmental biology. Homologous hox genes in such different animals as insects and vertebrates control embryonic development and hence the form of adult bodies. These genes have been highly conserved through hundreds of millions of years of evolution. Evolutionary developmental biology (informally, evo-devo) is a field of ...
Molecular & Computational biology 3 hours ago 0. 18. Paleontologists unearth what may be the largest known marine reptile. The fossilized remains of a second gigantic jawbone measuring more than ...
Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly cell biology, genetics, biophysics and biochemistry. [1] [2] Molecular biology tries to explain the interactions between the various systems of a cell. It studies the relationship of DNA, RNA and how ...
Organ (biology) In a multicellular organism, an organ is a collection of tissues joined in a structural unit to serve a common function. [1] In the hierarchy of life, an organ lies between tissue and an organ system. Tissues are formed from same type cells to act together in a function. Tissues of different types combine to form an organ which ...
The biology of sexual orientation has been studied in detail in several animal model systems. In the common fruit fly Drosophila melanogaster, the complete pathway of sexual differentiation of the brain and the behaviors it controls is well established in both males and females, providing a concise model of biologically controlled courtship.
Pregnancy may increase biological age by 2 years—though some people end up ‘younger’. By. Phie Jacobs. 22 Mar. 2024. Body’s cells appear to age faster during pregnancy, but they might recover—and even thrive—in the months after birth. ScienceInsider.
Mutualism (biology) Hummingbird hawkmoth drinking from Dianthus, with pollination being a classic example of mutualism. Mutualism describes the ecological interaction between two or more species where each species has a net benefit. [1] Mutualism is a common type of ecological interaction, one that can come from a parasitic interaction. [2]
