Some mistletoe species (Loranthaceae) resemble their host plants to a striking degree. Various mechanisms have been proposed for the developmental origins of novel traits that cause mistletoes to appear similar to their hosts, as well as for the adaptive phenotypic evolution of such traits. Calder (1983) proposed a logically flawed group selectionist seed-dispersal hypothesis for mistletoes to resemble their hosts. Calder's (1983) hypothesis does not provide a viable potential explanation for mistletoe resemblance to hosts.
一些槲寄生物种（桑寄生科）与它们的寄主植物极为相似。对于导致槲寄生与寄主植物相似的新性状的发育起源，以及这些性状的适应性表型进化，已经提出了各种机制。考尔德（1983年）提出了一个逻辑上有缺陷的群体选择主义种子传播假说，用以解释槲寄生与寄主植物相似的现象。考尔德（1983年）的假说并未为槲寄生与寄主植物的相似性提供一个可行的潜在解释。
