|
|
evolution only happens when there are common ancestors.
|
|
|
Common ancestors make evolution happen more quickly.
|
|
|
evolution can never take place with common ancestors.
|
|
|
the more two organisms have in common, the more recent is their common ancestor during their evolution.
|
Detailed explanation-1: -evolution can never take place with common ancestors. the more two organisms have in common, the more recent is their common ancestor during their evolution.
Detailed explanation-2: -Common ancestry allows Darwin to infer what happened in the lineage leading to modern mammals. The fact that present day birds and reptiles have sutures but no live birth is evidence that sutures were present in the lineage leading to modern mammals before live birth evolved.
Detailed explanation-3: -When a recent common ancestor is shared between two organisms, they are said to be closely related. In contrast, common descent can also be traced back to a universal common ancestor of all living organisms using molecular genetic methods.
Detailed explanation-4: -That’s because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven’t had as much time to accumulate random mutations in their genetic codes.
Detailed explanation-5: -Fossils, anatomy, embryos, and DNA sequences provide corroborative lines of evidence about common ancestry, with more closely related organisms having more characteristics in common.
