Researchers have noted that ants arrange their dead using the same
principles thought to produce the markings on animal skin and on tropical sea
shells, a first clear example of so-called Turing patterns in higher organisms.
Line Turing argued that activation occurs through a feedback process that amplifies
(5) small variations in the concentration of one of the ingredients, while inhibition
causes a concentration of activity to suppress the appearance of similar
concentrations nearby. Ant graveyards are an example of a self-amplifying
activation process: ants are more likely to drop a corpse on a pile than
elsewhere, and because collecting bodies and adding them to a pile sweeps the
(10) surrounding space clear, new cemeteries are inhibited from appearing in the
vicinity of existing ones. While activator-inhibitor mechanisms have previously
been proposed to explain how predators and prey distribute themselves across an
ecosystem, it is the first time such a system has conclusively proven that
Turing’s process operates at the level of colonies and ecosystems. [br] The author considers the example of the creation of ant cemeteries to be novel for which of the following reasons?
选项
A、Ant cemeteries exhibit elements of activation but not inhibition, a proposition formerly questioned by Turing’s theory.
B、Ant cemeteries exhibit Turing patterns in the absence of the predator-prey system.
C、Ant cemeteries involve self-amplification activation, as opposed to amplification from outside sources.
D、Ants are considered a higher organism, in which Turing patterns have never previously been established.
E、Turing’s theory has only explained the distribution of ants across the ecosystem, until now.
