For a long time, the prevailing idea was that parasites and pathogens evolve to target a particular host and as they get better at infecting
a specific animal or plant, they become less effective at infecting other organisms.
Not exact matches
When considering the protein source, for example, one must not only consider whether an
animal -
or plant - based protein will be used, but the
specific organism from which it is derived (e.g.,
animal: chicken, beef, lamb, pork, etc.; fish: salmon, menhaden, etc.;
plant: corn gluten meal, soybean meal, etc.), what part (s) of that organism will be included (e.g.,
plant: whole wheat vs. wheat germ vs. wheat bran;
animal: entire
animal vs. skeletal muscle vs. organ meats), and the form in which it will be added (
animals: frozen, fresh, meal), all of which affect the diet in terms of cost, nutrient composition and stability, manufacturing requirements, and ingredient handling, transport, and storage.
that then narrows on a
specific plant or animal.

Since nematodes are the only known organisms to use ascarosides, «we don't have to be afraid of interfering with similar biochemistry in
animals,
plants or humans,» Schroeder said, as researchers seek to identify species -
specific ascaroside molecules that may enable novel approaches to deter
or disrupt the survival
or reproduction of parasitic worms.
Following Campbell's logic, that would mean that it is the
specific proportion of amino acids that drives tumor growth, regardless of whether those proteins are of
plant or animal origin.
I don't think protein restriction (as some
animal lifespan studies) is really feasible
or wise, but moderation of
specific amino acids like methionine may account for some of the advantages of
plant protein sources.
While some people believe that diets work because you eliminate all
plants (carnivore / zero carb)
or animals (i.e. vegan), I'm sceptical about the «magic» of any
specific dietary approach.

Using genomic technologies — those that examine the entirety of available genetic diversity in individual
plants or animals and populations of those individuals — scientists can identify beneficial genetic traits and bring together new combinations of genes that enable crops and
animals to perform well in
specific environments.
Genetically modified organisms (GMOs) are created by introducing
