- Question: Some slime molds have some morphological similarities to fungi such as during times of stress they will develop into fruiting bodies 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 of

- Question: A common characteristic of eukaryotes that was likely present in the last common ancestor is the ability to form haploid cells with recombined chromosomes which then fuse together to form a diploid cell. This process is termed

In recent years, however, some molecular analyses have controversially suggested that ctenophores (comb jellies) may in fact have branched off first. Why is it so difficult to determine early animal phylogeny?
