Tangled bank hypothese
WebThe hypothesis has since been extensively used in theorizing the evolution of sexual reproduction. Unlike theories centered around responses to environmental factors (see Tangled Bank ), the Red Queen Hypothesis states that biotic factors are the key driver. Sex creates a highly uncertain environment due to the ever changing spectrum of genotypes. WebThe Tangled Bank is an attractive explanation for the prevalence of sex in relatively stable and saturated communities in tropical and marine environments where competition for resources is likely to be contin-ual and intense. Nevertheless, the evidence from crops and Chlamydomonas has persuaded me that it is unli-kely to be correct.

WebOct 19, 2016 · The Tangled Bank hypothesis and its variations [18,117] propose that the phenotypic diversity of sexuals enables them to share the resource space more efficiently than a homogeneous array of clones interfering with each other's success.
