Answer:
2%
Explanation:
The scientist believe that around 2% of the species that existed on Earth have been preserved in the fossil records. It is still a hot debate about it though, as there are only around 250,000 species identified in the fossil records so far, which is less than a quarter from the species that live in the present.
The reason why scientists believe that the majority of the species have not been preserved are very logical though. One of the reasons is that lot of species existed very long time ago, so their remains just didn't lasted so long. Other reason is the movement of the plates, where we have situation where plates that existed in the past have been totally suducted and melted in the mantle, while others are at the verge of it, so every fossil with them is melted and destroyed too. Another reason is that lot of species do not have hard parts, solid bone structure, so their preservation has been pretty much impossible,
Answer:
<u><em>Historia de la genética se considera que comienza por el trabajo del monje Agustino Gregor Mendel. Su investigación sobre hibridación en guisantes, publicada en 1866, describe lo que más tarde se conocería como las leyes de Mendel</em></u>
<u><em>La genética molecular se encarga del estudio de la estructura y la función de los genes a nivel molecular. Para poder entender debemos de saber qué constituye el material genético, qué es un gen, qué es el aDN, cómo llevar a cabo la secuencia de nucleótidos, entre otros aspectos relevantes</em></u>
