The answer is temporary isolation
Further Explanation
Temporary isolation (temporal)
Two species that mate at different times (days, seasons or years), the gametes will never mix.
The Process of Evolution In the 3.5 billion years since life appeared on earth, evolution has produced a very wide variety of living things. Millions of species evolve, while others cannot survive and become extinct. By studying the fossil record, scientists study evolution patterns.
According to Darwin, variations in the population are the "raw material" of evolution. Because mutations can produce variations, they are also considered evolutionary raw materials. Through natural selection, these variations are selected and leave organisms with properties that are appropriate to their environment. But how can evolution produce new species, even different kingdoms?
When Darwin proposed his theory, he was not aware of the existence of genes, DNA, and the mechanism of mutations that can cause variations. Darwin is also not familiar with genetics and molecular biology.
Speciation is the process of forming new species. According to his understanding, species are populations of living things that can reproduce each other and produce fertile offspring. However, it cannot reproduce with other groups. Based on this, it is seen that reproduction between one species with another species is impossible because there is isolation between species. Therefore, the key to species is reproductive isolation.
Prazigote Isolation is isolation that causes two species cannot mate or isolation that prevents fertilization. Based on the cause, isolation of the prazigote is divided into 5, as follows:
- a. Temporal isolation
- b. Ecological isolation
- c. Isolate behavior
- d. Mechanical insulation
- e. Gamete isolation
