Correct answer: D). Contradicted the accepted belief in spontaneous generation
Rudolf Virchow's and Louis Pasteur's contradicted the theory of spontaneous generation, which state that living organism originates from non-living matter.
According to this theory, it was believed that dust creates fleas, maggot arises from the rotten meat, wheat and bread left in the dark corner produces mice.
Louis Pasteur was the first scientist to prove that cells originate from the pre-existing cells.
Rudolf Virchow proposed that Omnis cellula e cellula, which means each cell comes from another cell.
Answer:
Behavioral isolation
Explanation:
<u>Temporal isolation</u> prevents different species from breeding with each other due to different mating times.
<u>Geographic isolation</u> is when a physical/geographical barrier prevents species from breeding with each other.
<u>Reduced hybrid viability</u> is when offspring from the result of two different species mating has a lower chance of survival.
<u>Behavioral isolation</u> is when different species experience reproductive isolation due to differences in mating rituals and/or signals.
Behavioral isolation makes the most sense here.
Answer:
ok this is point less but whatever you want
Natural selection is the process where the individuals with better traits survive ( in where they are ) while the individuals with less suited traits for that environment dies.
In your case, wouldn't the answer be something among the lines of "The humans with bigger jaws and more teeth found it difficult to eat or find enough food to satisfy their stomachs"? ( It makes sense. Usually, if the animal has bigger features, like mouth, and more teeth, they would need more food or nutrient to grow those bigger features. If one has bigger/more features, then that typically means they are bigger as well, which also means they need a bit more food. ^^ Yes, my logic is a bit weird, but it helps out. )
