Key Concepts

Fossil Record

The fossil record is the collection of all known fossils, which provides physical evidence of past life and the evolutionary history of organisms. Fossils, such as bones and teeth, help scientists understand the morphology, diversity, and temporal sequence of species that have existed on Earth.

Molecular Clock

The molecular clock is a technique in evolutionary biology that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged. It assumes that genetic mutations accumulate at a relatively steady rate and allows for the estimation of divergence times among species.

Homology

Homology is the concept that structures or genes in different species share a common ancestry, leading to similarities in their form or function. It is a key principle in evolutionary biology used to infer relationships among organisms by identifying traits inherited from a common ancestor.

Molecular Data

Molecular data involves the analysis of DNA, RNA, or protein sequences to study evolutionary relationships. It is used to compare genetic material across species, build phylogenetic trees, and estimate divergence times, providing detailed insights into the evolutionary process.
