Darwin lived in a time where natural selection was a strange theory among scientists and researchers. This was especially true when other researcher Lamarck argued that organisms passed on helpful traits to their offspring, that they magically could form a new trait to adapt to their environment and then pass it onto their offspring. For example, if a giraffe was too short to reach food, it would grow a larger neck in its lifetime and then pass that trait onto its offspring. Darwin argued that, through the process of survival of the fittest, that short giraffe would die off and never receive the chance to pass on its shortness to future populations. Thus, taller giraffes would survive— they can reach food, shorter giraffes can’t— and the short genes would disappear. The fact that Darwin was introducing a new theory that nobody was used to at the time was peculiar, so he had few people on his side until long after his observations.
Another problem Darwin had was the lack of technology. To travel, Darwin would have to use boats to reach far away places, and of course, this took time.
The final problem Darwin had was the extra time it took for evolution, a process that can take up to millions of years. Evolution didn’t occur over night— it took time for Darwin to conduct experiments, observe, conduct them again, come to a conclusion, and so on.
Hope this helped a little!
Answer:
The environment that it lives in has not changed much, therefor there is no need for evolution to take place.
Explanation:
Answer:
Explanation:
Plants use carbon and release oxygen, and animals release carbon and use oxygen.
Answer:
Evolution - It occurs due to the continuous variations and diversifications coming from the past generations
Natural Selection - In this process, the individuals are naturally selected by the environment that fits in perfectly!
Evolution - Driven by natural selection
Natural Selection- Driven by new characters that are the results of mutations
Evolution - Duration of Action Acquires millions of years
Natural Selection - Can be done in a short duration
Evolution - Example ;- Darwin’s finches, bright-colored peacocks, Mexican cavefish, etc.
Natural Selection -Example ;- Tree-frogs are mostly eaten by snakes, giraffes with short and long necks, etc.
