Why+can+populations+differ+from+ancestor+to+ancestor?


 * A population is a group of individuals of the same species. Could a population living today differ from their ancestors from many generations ago? Why or why not?


 * 1) Yes, they could differ after many generations because an environmental change can cause individuals in each generation to try to change some of their inherited traits to ones that are better suited to the new environment.
 * 2) Yes, they could differ after many generations because an environmental change can affect which inherited traits are most helpful, and therefore which individuals are more likely to survive and reproduce.
 * 3) Yes, they could differ after many generations because an environmental change can cause individuals to use some of their inherited traits more than before and pass down better versions of those traits to their offspring.
 * No, they could not differ after many generations because all members of a population are the same species and therefore have the same set of inherited traits.

If you thought B you're correct, if a certain organisms has favorable traits for certain environmental factors it will be more likely to reproduce and pass that trait down. While organisms who do not have that trait are more likely to die, and not pass their traits on.

The misconception is that a species ancestors will be exactly identical to it's current species, they would be wrong because populations slowly evolve from generation to generation with no noticeably changes. If we were to look at how the //Homo// genus changed across thousands of years, we could see clear changes. But if we were to look at our last 5 generations, changes would be very difficult or impossible to see.

Website Explanation: //A population can differ from its ancestors because an environmental change can affect which inherited traits are most helpful and, therefore, which individuals are more likely to survive and reproduce.//

Example 1: This bird would survive with an environment with food sources like bugs and nuts, it's strong and big beak would let it eat much more.

Example 4: This bird would survive with an environment with many flowers, the small narrow beaks would make it easier for bird eat nectar.

The bird best suited for the environment will pass on their favorable traits, those who die do not.

Populations change from each gen because the environment changes. Organisms with the optimal traits survive and reproduce #evolution ||
