Science SC question (1 Viewer)

[z600]

I am not too sure about the answer i have given for the following question.

Describe the process of natural selection and outline the evidence for present day organisms having developed from DIFFERENT organisms in the past.

The first part of describing natural selection is fine. For the second part I wrote about the evidence of trasition fossils and comparison DNA. I reasoned that trasition fossils show that a particular species can only evolve from a certain specie(s). And DNA comparison tells us that there are huge differences between oraganisms/species and are very differnt. A example of this is a humand and a fly has huge anatomical and genetic differences, thus they must have evolved from a differnt organism from the past.

Any views of the question and views?

Basically:

-molecular comparison
-homology
-fossil evidence

And explain each.

I don't like your human-fly argument. An example is that DNA comparison shows that chimpanzees and humans have very similar DNA genomes, which is strong evidence for a common ancestor.

FOr fossil evidence, what can i say? That we found fossils that shows that a particular specie gradually evolved??

i agree with vulgarfraction, doing chimpanzees with human is much easier, alot of the fossil and DNA proves that we are VERY similar.

Research on how the fossils of a species relates to human and how it's transformed throughout the years due to natural selection.

if you get what i mean..lol. GOODLUCK!

Fossil evidence and carbon dating showing gradual evolution works.. and also showing organisms in the past which would be likely to be ancestors of many organisms today (diverging evolution).

Had my science trials today...i think i did well

you guy done yours?

 

[vulgarfraction]

Hmm.. trial was today.

They just put past school cert stuff in I think. It was so easy. Like insultingly so.

Talk about the whole grade overstudying...

 

[vulgarfraction]

They do that for maths. But, meh, that's not the point.
