Title: Why is sexual reproduction most likely the ancestral state in eukaryotes?
Post by: niikiii on Feb 7, 2018
Why is sexual reproduction most likely the ancestral state in eukaryotes?
 
  a. Asexual reproduction is completely absent from basal unicellular eukary-otes.
  b. Under the parsimony principle, the most common form of a trait's state is always the ancestral state.
  c. The twiggy distribution of obligate asexual reproduction in phylogenetic trees makes it more likely that asexuality is a derived trait.
  d. Evolutionary models suggest that obligate asexual taxa are more prone to extinction than sexual ones.
