There are many biological reasons, also, why the Theory of Evolution
is valid. I will attempt to cover the current evidence
biologists use to support the theory
, adding my own attempt to stand up for sanity
. As for bol
's mention of religion; many religions have come to accept that creation
is not a valid theory.
Biologically, there are 6 major areas that support Evolution: Fossil Record
, Comparitive Anatomy
, Study of Intermediate Forms
and Molecular Biology
. These are discussed briefly below.
- Fossil record
- During the embryonic development organisms often develop structures that resemble those seen in ancestral adults.
e.g. Human embryos with gills, gills are lost later in development
- Comparitive Anatomy
- Organisms may share basic structural forms that suggests common ancestry (Homologolous structure).
e.g. Forelimb structures
- Study of Intermediate Forms
(the study of the distribution of organisms)
- Evidence of modern animals being decended from ancestors in the same area.
- Molecular Biology
As with bol
's write-up, these facts do not prove
the theory of evolution without doubt, but they do show it to be a very valid theory.
This is NOT a cut-and-paste write-up.
