In the 20th century, animals such as mules and ligers that had parents of different species were considered biological flukes, but genetic sequencing is beginning to unravel the critical role of hybridization in evolution.
Microfluidic systems redefined biology by providing platforms that handle small fluid volumes, catalyzing advancements in cellular and molecular studies.
The genomes of living animals are littered with DNA from long-gone relatives, providing a lens on evolution, past extinctions, and perhaps even solutions to agricultural problems.
