Hi Joe,
You wrote,

horse or a burro, but was an ancestor of both. My question now is whether
it is your interpretation or Ted Dace's or some combination of both that is
closest to being correct.
<< Males fight for feamles during mating season by butting heads.
Males are dintinguistable at a distance from females because of their
different
gazing habits. Males tend to stretch their necks to reach the tops of taller
trees,
while females tend to bend over smaller trees. Food is split equally between
male and female.
Rival males fight by swinging their necks and striking with their heads fom
side to side, they may use the head to give blows during contests.
The webpage mentioned below, states something that could be considered
as ' neckwrestling ', but it is also mentioned that combats are rare, as
bulls
from the same area all know their place.
It would seem odd to me though, that something rare as a real combat, and
therefor the neckwrestling would be selected by nature, and select for
longer necks in the first place_ just for sexual purposes !?
It sounds plausible, but I stay unconvinced !
A longer neck to keep out rivals, ok I can live with that, but than as an
exta bonus, as a result of such process, having a foodsupply entirely for
their own !? Killing two birds with one stone !?
Nature can do a lot, it is possible that both adaptations evolved simul-
taneously_ each time they got longer necks, they switched to another
foodsupply !?
Possible, but IMO unlikely, if they evolve further, they will starve.
