The idea that species come from other preexisting species is most famously associated with Charles Darwin. In his theory of evolution by natural selection, outlined in "On the Origin of Species" (1859), Darwin proposed that species evolve over time through a process of variation and adaptation. This concept fundamentally changed the understanding of biological diversity and the relationships among living organisms.
When a species dies out completely, it becomes extinct.

According to the theory of evolution, originally proposed by Charles Darwin in his book "The Origin Of Species" human beings and monkeys are both descended from earlier primate species. Monkeys, according to this theory, would be more accurately described as our cousins, than as our ancestors. So actually, nobody has said that people come from monkeys. That would be a misrepresentation of evolutionary theory.
As you said- different species. Diferent species have different geneticmaterials, and it does not match up. Like trying to put a DVD in a VCR.
Endangered or threatened. These species are at risk of becoming extinct if steps are not taken to protect and preserve their populations.
Matthias Schleiden, Theodor Schwan, and Rudolph Virchow all stated that cells must come from existing cells. This is known as the cell theory.
When a species permanently disappears the species is said to be extinct.
If they are the last species of its kind it would be come extinct
If they are the last species of its kind it would be come extinct

The species is said to be extinct.
yes; if a cell is said to be present, then it was originated by the division of it's mother cell.

A species that has few surviving members is said to be endangered.
A species that dies out is said to be extinct. If this doesn't answer your question, please let me know.
