I need help on this question in biology and biology is hard and confusing
Yuliya22 [10]

Answer:

b. the new species must be unable to breed with the original species.

Explanation:

By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.

These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:

  1. Habitat isolation: Two species occupy entirely different and distant habitats.
  2. Temporal isolation: Two species  procreate at different times of the year.
  3. Behavioral isolation: Two species exhibit different mating behaviors.
  4. Gametic isolation: The gametes of the two species cannot fertilize.
  5. Mechanical isolation

Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.

Tanya [424]

One valid inference that can be made regarding the evolution of modern horses is that : Pliohippus had teeth adapted for grazing

<h3>Description of Pliohippus </h3>

From the information provided in the question The modern day horse resembling the pliohippus can be inferred to have teeth which is adapted for grazing just like the pliohippus.

The pliohippus evolved from the merychippus which is classified as a grazer. because of its longer/taller teeth the pliohippus was more adapted to grazing than been a browser.

Hence we can conclude that One valid inference that can be made regarding the evolution of modern horses is that : Pliohippus had teeth adapted for grazing
