Beagles are man made. they are created so man can used them to hunt. Dogs are usually dependent on humans so most will not live with out humans. With that said, Beagles were breed to have highly developed nose. Their legs are short so they can be closer to the ground and thus closer to the scent. Their long ears are there to sweep up the ground so it can sweep up scents. Finally they have a very developed scent system.

The only traits that can lead to natural selection and evolution are traits that?
influence either survival or reproduction.
What will happen to a species if its traits are insufficient for its survival?
It will go extinct.
What are traits that improve an organisms chance of survival?
Don know
Do inherited traits and adaptations determine survival and reproduction?
Yes, due to natural selection and survival of the fittest only the best traits get passed on the offspring to assure survival. The ones with the best genes will also be able to produce more offspring
What traits that improve an organism chance for survival?
its color and its body parts
What are traits that improve an organism's chance of survival called?
Don know
Which process is most responsible for passing on traits needed for survival?
reproduction
What is the similaritys between artificial and natural selection?
they are both weeding out unfavorable traits for favorable traits to be well equipped for survival
Why are some traits common than others?
Traits were once needed for a reason. It was probably necessary for survival a while back.
What type of traits does natural selction act on?
Heritable traits that confer some survival or reproductive advantage, or natural selection will cull traits that confer the opposite to survival and reproductive advantage. So, the individual organisms, or his genes, are selected and these alleles increase in frequency in populations and evolution takes place.
Why are stronger traits passed down to offspring?
So that the offspring have a better chance of survival. these traits are often chosen through natural selection.
What Evolutionary perspective put forth by some biologists maintains which position?
genes that produce behaviors and traits that lead to survival are passed on to the next generation
