How is charles darwin's theory of evolution...?

Question

important to biology?

i'm not asking for you to do my homework :P maybe put bullet notes, i have everything down but i don't know how it's important to biology.

Answer 1

There is a famous quote (and an essay of the same name) by the great biologist Theodosius Dobzhansky:

"Nothing in Biology makes sense except in the light of evolution."

Specifically, evolution explains:

* Why all of life can be organized into a systematic hierarchy of *branching* hierarchies.  

* Why the same coding system is used for *all* life forms (e.g. we don't see some left-handed DNA, some right-handed ... the same 3-base codons translate to the same amino acids ... all life forms use the same set of only 20 amino acids ... etc.)

* Why there is so much junk DNA.

* Why there certain sequences of DNA are letter-by-letter identical between certain organisms in the tree, but slightly different between others.

* Why these similarities extend into junk DNA (i.e. why two species would contain the same junk DNA letter-for-letter when the DNA itself serves no purpose to *either* species.

* Why we see the same metabolic pathways used in all organisms, even though they are not the most efficient in all situations.

* Why there are physical characteristics in common ... e.g. why the same bone structure serves many different purposes in bat's wings, human hands, mole's diggers, dog paws, horse's hooves, etc.)

* Why some structures are subject to design problems or downright bizarre structures (like all the bones in the inner ear).

* Why embryos develop the way they do.

* Why fossils with progressive structures are found in exactly the right depths in the soil, in exactly the right locations around the world.  (E.g. we don't find kangaroo fossils in Africa, or giraffe fossils in Australia.)

* Why bacteria and viruses develop immunity to vaccinations, antibiotics or antivirals.

* Why mitochondria have separate DNA from the rest of our cells.

And on and on.

Basically, if you reject evolution, you reject the central *UNIFYING* idea of modern biology.  Biology becomes a huge mess of completely *unconnected* facts.

Answer 2

Charles Darwin's theory, opened up our mind about evolution.

And of course make some human confuse about the truth..

Because in my religion. Human is made by God.

But actually Charles Darwin never say human was evolution from monkey or else. But he said a theory of evolution, which said every life things must adaption, and from that adaption there's evolution. Monkey can evolution many times... then can be like human.Then the mass media turn his words become human was evolution from monkey.. That's the wrong statement..

Answer 3

lol, it's the root of ALL biology and how every single life form got the form it's currently in.

Answer 4

It is just a theory only
