Researchers tracked the movements of endangered caribou and sequenced a portion of their genomes to determine which genes may influence migratory behavior.
Immunoglobulin genes might have evolved much earlier than previously expected, perhaps even in the common ancestor of Cnidarians and Bilateria, a study suggests.
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.
A high-quality reference genome for this vulnerable feline may help scientists understand why they’re so prone to transitional cell carcinoma in captivity.
Splitting Chinook salmon into two groups based on their DNA could aid conservation efforts. But some researchers argue that this would be a misuse of the data.
