In the 1930’s and 1940’s a new whooping crane breeding ground in texas was discovered, which contained about 25 whooping cranes. their numbers started to steadily climb in the 1960’s and 70’s. in 1980, there were 75 individuals reported, and by 2000, there were 150 reported. if their population growth continued at the same rate and the population is not limited by any carrying capacity due to the environment, based on the population values in 1980 and 2000, how many whooping cranes would you predict to see by 2040?

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
