Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
One problem with fossil evidence is ____ ?
A
Its not real
B
Fossils are very old
C
There are far too many fossils
D
There are very few fossils that show missing links
Explanation: 

Detailed explanation-1: -Many fossil records are incomplete because some animals were soft bodied or soft tissue which decays quickly. Also, due to movement of tectonic plates, fossils are destroyed so there are many new fossilised organisms which are destroyed and we don’t know about them.

Detailed explanation-2: -The history of evolution consists of countless “missing links, ” as species continuously adapted to their environments over time and were replaced by evolved descendants or became extinct. “Probably the most important thing is that most of the fossils we find aren’t actually links, ” Hawks said.

Detailed explanation-3: -The Bird Missing Link-Archaeopteryx Not only does Archaeopteryx count as “a” missing link, but for many years in the 19th century, it was “the” missing link, since its spectacularly preserved fossils were discovered only two years after Charles Darwin published On the Origin of Species.

Detailed explanation-4: -missing link, hypothetical extinct creature halfway in the evolutionary line between modern human beings and their anthropoid progenitors. In the latter half of the 19th century, a common misinterpretation of Charles Darwin’s work was that humans were lineally descended from existing species of apes.
