Since there are over 10 varieties of homid, there are plenty of intermediate forms, even among the homids.
As for species becoming more complex over time, there is evidence of that, but there is (and should be) evidence of species becoming less complex over time. The latter is seen in parasites from mistletoe to suckerfish.
As for parasites, does anyone know of any creationists actually doing research, instead of engaging in apologetics?
The thesis that a parasite is “less complex” is based on little more than a cursory examination of the situation. Obviously the parasites have solved the problem of where and what to eat ~ something that continues to elude we puny humans.
Got a great idea!
