Some slime molds have some morphological similarities to fungi such as during times of stress they will develop into fruiting bo
dies that produce spores. However, DNA analysis doesn't indicate a direct common ancestor, but it is thought that the similarities are due to environmental pressures, which is an example ofA. vestigial structures B. homologous structures C. divergent evolution D. convergent evolution
Slime moulds are the fungus-like protists which bear a structure called sporangium which produces spores. The sporangium is produced in fungi as well due to which these protists are called fungus-like. Although both produce sporangium but they are not closely related, rather they are distantly related organisms.
The appearance of a sporangium in both indicates that they had faced the same conditions due to which they both showed the same adaptation by producing the same structures performing the same function. In evolutionary terms, this is an example of convergent evolution.

Although the DNA packaging with histones proteins is mean to form nucleosomes (groups of 8 histones proteins), the higher structures why the genetic material is packaged with those molecules is to form chromosomes, as you said.
