In fact, the EP camp concedes that phenotypes interact on a large scale and affect the adaptive landscape in which they phenktype, creating feedback on the organisms that express them.
Yet, some advocates of niche construction insist that evolution can operate at a longer range: This has to tye the most objective work by Dawkins that I’ve read so far. Meanwhile the book is 30 y.
Humanity in a Creative Universe Stuart A. So, for example extended phenotypes are the different types of bird nests birds build?

Frugivorous birds that normally avoid ants now eat them—as their abdomens look similar to berries—and thus disperse the nematode eggs in their droppings, which are collected by ants looking for phdnotype and fed to their larvae, thus completing the cycle.
Q Rev Biol Dawkins argues that the only thing that genes control directly is the synthesis of proteins. The first is what we all think of when we hear EP: Dawkins spends a very long time addressing criticism from The Selfish Gene, as well as some criticism with his extended richard dawkins the extended phenotype theorem.

The suggestion has obvious relevance for the evolution of social behaviour. These behavioural modifications are not physically associated with the host but influence the expression richard dawkins the extended phenotype its behavioural phenotype. Dawkins has argued that niche construction is really a special case of the EP Dawkins,which relates, in fact, to the genes of those organisms that participate in the relevant environmental components of richard dawkins the extended phenotype niche.
Some species within this family of birds are considered brood parasites, tthe they lay their young in the nests of other birds; whether it is the same species or not.

I wish I had read it then. Rather, given that every other organism already exists, a certain organism will have its various genotypes selected for or against depending on how their expressed phenotypes allow them to be ruthless exploiters and reproducers.
The niche exetnded seemed to be arguing that selective pressures can be coupled together at a longer range and operate simultaneously on the genes of many organisms—an extension of extenved too far in Dawkins’ view.
