Questions and Correct Answers Latest 2025;
a phylogenetic tree is a -
** hypothesis about the evolutionary history of taxonomic groups
why do we believe that "at the least" male Homo sapiens neanderthals mated with non-African
ancestral Homo sapiens sapiens? -
** because neanderthal nuclear DNA sequences are present in the human gene pool
how does the level of genetic variation in humans typically compare to other species? -
** lower than other species
one reason we see relatively little genetic variation among human regional populations is that: -
** humans migrated out of Africa so recently that we haven't had enough time for regional
variation to accumulate
adult humans display several traits very similar to traits seen in juvenile of our sister group, the
chimpanzees. what is the evolutionary explanation for this? -
** some adult human traits are thought to be neotenic
humans are members of the monophyletic -

** the recipe, because it can be passed on to all relatives through learning
to which super kingdom does the organism that causes amoebic dysentery belong? -
, ** amoebozoa

unnecessary
to which superkingdom do camels belong to? -
** opisthokonta
why is the eukaryotic tree of life unrooted? -

eukaryotic diversity? -
** increase in O2
red tides are caused by organisms in the Superkingdom Ranelamintha -
