R_3_15 — Epigenetics and Lamarckian Inheritance: Transgenerational Mechanisms Beyond DNA Sequence

Epigenetics — the study of heritable changes in gene expression that occur without alteration to the underlying DNA sequence — has fundamentally reshaped modern biology since the term was coined by Conrad Hal Waddington

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

R_5_02 — Megafauna Extinction: Quaternary Losses and the Overkill Debate

Between ~50,000 and 10,000 years ago, Earth lost the majority of its large-bodied animals (megafauna >44 kg) — woolly mammoths, ground sloths, saber-toothed cats, giant wombats, moa, and dozens of other spectacular speci

R_2_05 — Missing Fossil Record and Punctuated Equilibrium

Darwin himself called the fossil record "the most obvious and gravest objection which can be urged against my theory" — because if evolution occurred through gradual transformation, we should find smooth transitional seq
