Evo Devo and the Mechanism of Evolution

Evolution, in the macroscopic sense, has probably been explained to you time and time again in your science classes as tiny changes that over time build up and create differences among species. From a single common ancestor, different species evolve, eventually creating the huge diversity of life we see today. But have you ever considered how that change comes about? …

The Biological Expedition of Memories

For several years, the origin of inexplicable fears such as arachnophobia or acrophobia has remained an enigma. How, why, and by what means such fears develop was a prevalently unanswered question, until a study involving mice opened a complex, intricate gateway into the world of epigenetics and provided some insight into this phenomenon. In fact, recent research and experimentation affirm …

Young Children’s Educational Literature: A Scientific Gap

Having more options is better.  Unfortunately, the parents and educators of young children do not have many picture book options in arenas of science such as genetics and DNA. Children develop their intellectual identity through their reading choices, and exposure to science in informal settings affects science literacy later in life. The dawn of the 1990’s DNA sequencing revolution allowed …

Questioning the Mouse Model’s Legitimacy in Biomedical Research

A model organism is a non-human species that is studied to understand biological mechanisms that can be applied to humans or other organisms. While a wide range of species can be studied as model organisms, the cornerstone of biomedical research is the house mouse. Mice have been used as model organisms for many decades [1]. Scientists across the world have …

Epigenetics: In Defense of Lamarck

Jean-Baptiste Lamarck has long been debunked. Or so the story goes. Lamarck formulated the theory that the environment shapes genes, and that these changes are passed on to your children; on other hand, Darwin argued that genes are not changed by the environment and formulated natural selection. Lamarckian evolution theories on environmentally acquired characteristics are often referenced and contrasted with …
