Species of anteaters in australia, africa, and south america are not closely related. however, they share similar characteristics that they use to eat ants and termites, including a long sticky tongue, large salivary glands, and a rugged stomach. this is an example of

This is an example of convergent evolution.

Convergent evolution is a process in which organisms that are not closely related or organisms of different lineages independently evolve similar features because they have to adapt to similar environments or selection pressures. This process produces analogous body forms that have the same shape or function but do not exist in the last common ancestor of those groups. From the question, the similar characteristics among the species of anteaters in Australia, Africa, and South America is an example of convergent evolution.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
