archaeopteryx

Question 2

adaptation vs variation

Answer 2

adaptaion=product of natural selection and always good

variation=basis of natural selection and can be good or bad

whats adaptive radiation

Answer 3

the divergent evolution and adaptation of species to different roles in new habitats

Question 4

example of adaptive radiation

Answer 4

galapagos islands-the finches wer egeologially isolated resulting in the new beaks to find food in the different environments

Post-zygotic barriers-

Answer 8

hybrid have problems with viability, fertility and hybrid breakdown after 1 generation

the ability for organixm to survive

Question 10

hybrid breakdown=

Answer 10

where the initial offspring are fertile and can have offspring but the second generation are sterile

whats the p value

Answer 24

p value is the probability that the deviation of the observed from that expected is due to chance alone
