Not necessarily. Plants as well as animals evolve independent of each other.
"In analyzing our interactome map of Arabidopsis, we found strong evidence of this rapid-then-slow process over the hundreds of millions of years of the plant's evolution," says Braun. "It provides the first-ever empirical evidence of evolution acting on protein networks."
First large-scale map of a plant's protein network addresses evolution, disease process
Also note the finding supports extinction, not evolution:
Humans driving extinction faster than species can evolve, say experts.
