kindly paraphrase the concepts discussed in this work:
1. Random mutuations resulting from sexual reproduction resulting from sexual reproduction resulted in a variety of bats in the ancestral population.
2. Some bats had the ability to create high pitches-sounds,and therefore could better avoid obstacles and detect prey listening to the sounds, and therefore could better avoid obstacles and detect prey by listening to the sounds bounce back.others bats did not have this ability.
3.those bats that had the abilty to create high pitched-sound were more likely to survive than bats that couldnt create high pitched sounds.That is,they could fly without encountering obstacles,and were more easily able to find food sources and survive.
4. therefore, bats that couldn't create high pitched sounds probably reproduced more than thos bats that couldnt create these sounds.
5.these bats reproduced and passed on more of their genes to their offspring, increasing the likeihood that their offspring also inherited the ability to create high piched sounds.
6. As such, the proportion of bats that could create these high pitched sounds increased within the population, and echolocation became prevalent within the population.
*we're studying darwin's 6 principle(source of variability, Intra species variability, differential survival rate, reproductive advantage,accumulation of change, changes within a population).
*please help me understand these principles by paraphrasing the 6 statements above and connecting it to darwins principle. thank you!
No two individuals are exactly alike and contain variations due to their genetic makeup. This applies to the first statement regarding random mutations and sexual reproduction. Genes can mutate spontaneously or due to environmental agents. If a mutation is something that may give a survival advantage, this organism may live and pass it along to offspring. The bats who could create high pitched sounds would have a survival advantage over those bats who could not do this. This would help with the struggle for existence. Living things compete for food, mates, shelter and to avoid predation. Echolocation would be an advantage in bats who possessed that ability. Therefore, there would be a differential survival rate-those with the ability would be better adapted and would most likely survive and reproduce. As time went by, there would be more individuals with this ability. As changes accumulate over time, due to mutations that were beneficial, eventually, the population would change and a new species would evolve.
