R_3_08 — Speciation Mechanisms and Reproductive Isolation

Speciation — the process by which one species splits into two or more reproductively isolated lineages — is the engine of biodiversity. Ernst Mayr's biological species concept (1942) defines species as groups of interbre

R_3_07 — Embryology and Morphogenesis: How Bodies Take Shape

Embryology — the study of how a single fertilized cell becomes a complex multicellular organism — is one of biology's most profound mysteries. From the discovery by Karl Ernst von Baer (1828) that embryos of different sp

R_3_01 — Epigenetics and Ancestral Memory

Epigenetics — heritable changes in gene expression WITHOUT changes to the DNA sequence — has revolutionized biology over the past two decades. Your genes are the hardware; epigenetics is the software that determines whic

R_3_13 — Evolution of the Immune System

The immune system is one of evolution's most elaborate and costly creations — vertebrate adaptive immunity alone employs V(D)J recombination to generate over 10¹¹ distinct antibody specificities from fewer than 400 gene
