Contemporary Natural Selection<\/div>\n
Theory: Mechanism & Criteria<\/div>\n
Is there a clear and focused academic scienti\ue0c4c\n <\/div>\n
conviction\/consensus on the mechanism and criteria\n <\/div>\n
for Natural Selection? The answer is NO.<\/div>\n

\n \ue0c4gures\u201d\n <\/div>\n
Main \ue0c4gures in selection debate<\/div>\n
\u201cBesides Richard Dawkins and George C. Williams,
\n other\n <\/div>\n
biologists and philosophers have expanded and
\n re\ue0c4ned\n <\/div>\n
the sel\ue0c4sh-gene theory<\/span>,
\n such as John Maynard Smith,\n <\/div>\n
George R. Price, Robert T<\/span>rivers,
\n David Haig, Helena\n <\/div>\n
Cronin, David Hull, Philip Kitcher<\/span>, and Daniel C. Dennett.\n <\/div>\n
Individuals opposing this gene-centric view include
\n Ernst\n <\/div>\n
Mayr<\/span>, Stephen Jay Gould,
\n David Sloan W<\/span>ilson, and\n <\/div>\n
philosopher Elliott Sober<\/span>.\u201d…\n <\/div>\n<\/p><\/div>\n

Proponents of multilevel selection (MLS) include E.

Michod, and Samir Okasha.<\/div>\n

Macroevolution and micr<\/span>oevolution\n <\/div>\n
\u201cOne of the tenets of the modern evolutionary
\n synthesis\n <\/div>\n
was that macroevolution (the evolution of
\n phylogenic\n <\/div>\n
clades at the species level and above) was solely
\n the\n <\/div>\n
result of the mechanisms of micr<\/span>oevolution (changes in\n <\/div>\n
gene frequency within populations) operating over
\n an\n <\/div>\n
extended period of time. During the last decades of
\n the\n <\/div>\n
20th century some paleontologists <\/span>raised questions about\n <\/div>\n
whether other factors, such as punctuated
\n equilibrium\n <\/div>\n
and group selection operating on the level of
\n entir<\/span>e\n <\/div>\n
species and even higher level phylogenic clades,
\n needed\n <\/div>\n
to be considered to explain patterns in evolution
\n revealed\n <\/div>\n
by statistical analysis of the fossil recor<\/span>d. Near the end\n <\/div>\n
of the 20th century some resear<\/span>chers in evolutionary\n <\/div>\n
developmental biology suggested that interactions\n <\/div>\n
between the environment and the developmental
\n pr<\/span>ocess\n <\/div>\n
might have been the source of some of the
\n structural\n <\/div>\n
innovations seen in macroevolution, but other
\n evo-devo\n <\/div>\n
resear<\/span>chers maintained
\n that genetic mechanisms visible\n <\/div>\n
at the population level are fully suf\ue0c4cient to
\n explain all\n <\/div>\n
macroevolution.\u201d<\/div>\n<\/p><\/div>\n
\"\"<\/p>\n
Epigenetic inheritance<\/div>\n
\u201cEpigenetics is the study of heritable changes in
\n gene\n <\/div>\n
expression or cellular phenotype caused by
\n mechanisms\n <\/div>\n
other than changes in the underlying DNA sequence.\n <\/div>\n
By the \ue0c4rst decade of the 21st century it had
\n become\n <\/div>\n
accepted that Epigenetic mechanisms were a
\n necessary\n <\/div>\n
part of the evolutionary origin of cell differ<\/span>entiation.\n <\/div>\n
Although epigenetics in multicellular organisms is
\n generally\n <\/div>\n
thought to be a mechanism involved in differ<\/span>entiation, with\n <\/div>\n
epigenetic patterns \u201creset\u201d when organisms repr<\/span>oduce,\n <\/div>\n
there have been some observations of
\n transgenerational\n <\/div>\n
epigenetic inheritance. This shows that in some
\n cases\n <\/div>\n
non genetic changes to an organism can be
\n inherited\n <\/div>\n
and it has been suggested that such inheritance can
\n help\n <\/div>\n
with adaptation to local conditions and affect
\n evolution.\n <\/div>\n
Some have suggested that in certain cases a form
\n of\n <\/div>\n
Lamarckian evolution may occur<\/span>.\u201d\n <\/div>\n
Unconventional evolutionary theory<\/div>\n
Omega Point<\/div>\n
\u201cPierre T<\/span>eilhard de
\n Char<\/span>din\u2019<\/span>s metaphysical Omega Point\n <\/div>\n
Theory describes the gradual development of the
\n universe\n <\/div>\n
from subatomic particles to human society<\/span>, which he\n <\/div>\n
viewed as its \ue0c4nal stage and goal. Cosmologist Frank
\n J.\n <\/div>\n
T<\/span>ipler subscribes to a
\n version of this theory<\/span>.\u201d\n <\/div>\n<\/p><\/div>\n
\"\"<\/p>\n
Gaia hypothesis<\/div>\n
\u201cT<\/span>eilhar<\/span>d de Chardin\u2019<\/span>s ideas have been seen by\n <\/div>\n
advocates of the Gaia theory proposed by James<\/div>\n
Lovelock, which holds that the living and
\n nonliving\n <\/div>\n
parts of Earth can be viewed as a complex
\n interacting\n <\/div>\n
system with similarities to a single organism, as
\n being\n <\/div>\n
connected to Lovelock\u2019<\/span>s
\n ideas. The Gaia hypothesis\n <\/div>\n
has also been viewed by L<\/span>ynn
\n Margulis and others as\n <\/div>\n
an extension of endosymbiosis and exosymbiosis.
\n This\n <\/div>\n
modi\ue0c4ed hypothesis postulates that all living
\n things\n <\/div>\n
have a regulatory ef<\/span>fect
\n on the Earth\u2019<\/span>s environment that\n <\/div>\n
promotes life overall.\u201d<\/div>\n
