It allows blackberry plants to adapt to new conditions.

Detailed explanation-1: -Wild blackberries reproduce asexually by sprouting new roots when stems touch the ground. They also reproduce sexually through their flowers. What is the advantage of the blackberry plant being able to reproduce asexually and sexually? It allows the blackberry plant to adapt to new conditions.
Detailed explanation-2: -Evidence that land vertebrates descended from fish includes transitional fossils, anatomical similarities among embryos and adult animals, and genetic evidence of common ancestry.
Detailed explanation-3: -Absolute Dating The nuclear decay of radioactive isotopes is a process that behaves in a clock-like fashion and is thus a useful tool for determining the absolute age of rocks. Radioactive decay is the process by which a “parent” isotope changes into a “daughter” isotope.
Detailed explanation-4: -The age of fossils can be determined by Radioactive isotope method and Relative dating method.In the relative dating method, fossils which are closer to the surface are more recent than the fossils we find in deeper layers.
