What does the theory of evolution contribute to conservation biology? it scientists understand how populations and species are related, and this knowledge can be used to these populations and species survive. it scientists understand how populations and species are related, and this knowledge can be used to capture and breed the fittest organisms in these populations and species. it scientists understand how populations and species react to changes in their environment, and this knowledge can be used to these populations and species survive. it scientists understand how populations and species react to changes in their environment, and this knowledge can be used to capture and breed the fittest organisms in these populations and species.

The Theory of Evolution was created by Charles Darwin. The theory has helped scientists to understand what they are studying. Evolution shows the process of a species developing and diversifying over time. The Theory gives an explanation for why some species are similar to the fossils that scientists find today. The evidence that evolution helps us understand the creation and relation amongst species would consist of Comparative Anatomy. This shows us the difference between homologous structures, analogous structures and vestigial structures.  

Homologous structures - structures w/ the same origin but adapted for different purposes. An example of this would be divergent evolution... this is the sharing of common ancestors but to start to evolve separately.
ex. humans, whales, bats 

Analogous Structures - structures w/ different origins in distantly related organisms adapted for the same purposes. An example of this would be convergent evolution... this is the sharing of different ancestors but that have evolved similar adaptations to fit their environment. 
ex. birds, flies 

Vestigial Structures -Structures that are present in organisms but no longer have any use bc they have been reduced in size or last over time. 
ex. Appendicts, tail bones, and leg bones to snakes

 There are also different methods of finding when fossils date back to. 
Overall the 4 main sources of evidence...

1. Comparative Anatomy - above ^^^

2. Dating Fossils - 
Relative: approximate age of the fossil based on its position on the rock layers using index fossils as indicators
Absolute: Determines exact age (in yrs) of fossil

3. Embryology - Closely related organisms have common early development stages 

4. Molecular Sequencing - DNA sequences of closely related organisms are similar. The more closely related two species are the more amino acids sequences they have in common. 

Sobascially that's to support the point that the Theory of Evolution helps scientists to study and understand a population of species and on how they can react and change in their own environments. 

I really hope this helps :)

The need activity of the nurse is to suction discharges from the trachea. current treatment approaches in the pressing consideration facilities or crisis offices are corticosteroids and nebulized epinephrine; steroids have demonstrated advantageous in extreme, direct, and even gentle croup. in the clear instances of croup, anti-microbials are not endorsed, as the etiology is viral
