New Species Forming Today?
Evolution predicts that new species are still evolving.
Unlike the creationist "kind," whose definition is changed as needed for the immediate argument,a species is easily recognized as a population which
(1) brings forth fertile young similar to itself,
(2) if it reproduces sexually, does not interbreed with other species and
(3) usually looks distinctive.
New plant species are produced routinely in agricultural work. A new genus with many new species, Triticosecale (Triticale) is now an important agricultural plant (A. Muntzing, Triticale Results and Problems. Parey: Berlin, 1979).
A fly (Rhagoletis pomonella) that normally eats hawthorn fruit during its larval stage gave rise to a race that infests apples (apple maggot) about 170 years ago. This race originated in the Hudson River Valley, and then spread over the eastern and midwestern U.S. The apple and the original hawthorn races now mate and lay eggs at different times, and so interbreed only rarely. Clear genetic differences exist, and the apple maggot may now be on its way to becoming a new species (Nature 336:13-14, 61-67, 1988).
Most people with pet dogs know about a new species of microorganism. Canine parvovirus, a lethal disease of dogs, evolved from <hl>feline (cat)parvovirus</hl> in the 1970s.
Demonstration of how salamanders are evolving into two different species in California:
One has camoflouge to protect it from predators
One has a foul taste when in mouth of predators.
