Answer:

Modern theory of evolution explains that "organisms change over time as a result of changes in heritable physical or behavioral traits". Hence this change suggests the loss of vestigial organs.

Explanation:

  • Vestigial organ are those which do not have any function but is present in our body.
  • According to the modern theory the genetic and physical appearance changes along with the adaptation in environment by the organism.
  • So if the organ looses its function in order to sustain and adopt in the changing environment then they become vestigial and slowly disappear.
  • This is the common example for the Lamarck's theory of "use and disuse".

GenaCL600 [577]

Answer:

Earth has been our place for many years. all inhabitants on earth are causing great destruction. along the way we tried to resolve issues yet some we couldn't figure out. the one we couldn't figure out had made a great impact on our world today. Just how do we stop it? Many ways actually, taking pollution for example. pollution is a great cause for why earth isn't as lively as before. along the years we've polluted 92% of the earths air. causing us to breathe unhealthy air. We can easily fix this problem with finding new ways to get somewhere like riding a bike or taking an energy efficient car. Therefore, we humans have change the world dramatically by doing good things and bad things, too. but in the end we are the ones causing earth to nearly give up, so we can also be the ones to let the earth forgive.

hope this helps you out!

TIP: change it up so you don't do plagiarism:)
