A paleontologist organized information about horse fossils found over time and created this diagram as a result of his information. What does his diagram show? AKS 14C
The horse has NOT changed over time.
The horse will eventually become extinct.
Horses developed smaller legs as well as smaller teeth over time.
The small ancestor of the modern horse evolved quite a bit over time.

The pressure in the past will be: raising temperature and flooding, more Co2 in the atmosphere. We might for example evolve to better extract the oxygen from the atmosphere and be better resistant to heat. Since we are far from extinction and we've spread all over the world, we are successful as a species. I believe that the environmental pressures that exist now and that may be shaping the human species are the use of land, the extraction of resources, greenhouse emissions and water use. This are being used by use more and more as we start overpopulating the earth. The pressures today are : the limited free land, limited resources and changing climate. They are connected to man-made global warming and overpopulation.

Explanation:

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
