Answer:

Statements thar are true:

Some  organisms have phenotypes that make them better  increase chances of reproduction.

Natural selection continues to occur even today

Phenotypes found In the most successful members of a species become the most prevalent after  several generations.

Explanation:

It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.

Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.

Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.

A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.

Fossils of the same type and same age have been found on different continents. If we were to put South America and Africa togeth
Ksivusya [100]

Answer:

there have been several cases where fossils of the same type and age where found on different continents.

For example:-

"The Mesosaurus" which is an extinct genus of reptile from the Early Permian and was found in the continents of southern Africa and South America.

This seems to point to the fact that once all the continents were togethe, and they are now separate due to the Continental drift. ( the theory that states that all the continents were earlier one big form of landmass, but they have moved away from each other thus appearing to have "drifted" across the ocean bed."

But again these are all just theories and speculations but findings like these strengthen them and make people believe in these theories. They haven't exactly been confirmed. Like the evolution theory.

i hope this helps.

have a great day ahead :)
