The bizarre genome of the world’s most mysterious flowering plants shows how far parasites will go in stealing, deleting and duplicating DNA.
A patchwork of genomic differences in the placenta may explain the organ’s “live fast, die young” strategy and its connections to cancer.
The simple insight that most changes are random had a profound effect on genetics, evolution and ecology.
Even genes essential for life can be caught in an evolutionary arms race that forces them to change or be replaced.
