A. a population of lizards may be brown or red. The temperature of the eggs determines the color of the baby lizards, and a brown parent lizard is equally likely to give birth to either color of offspring. B. a population of spiders includes individuals that build their webs in triangle shapes and others that build their webs in round shapes. They inherit their web-building strategies from their parents and all shapes are equally successful at catching insects. C. some gazelles are capable of running faster than others, a skill that is partially genetic Faster gazelles tend to live longer and have more offspring.   A. Population A

Question
1. Which of these populations has all the characteristics needed to evolve by natural selection?
A. a population of lizards may be brown or red. The temperature of the eggs determines the color of
the baby lizards, and a brown parent lizard is equally likely to give birth to either color of offspring.
B. a population of spiders includes individuals that build their webs in triangle shapes and others
that build their webs in round shapes. They inherit their web-building strategies from their parents
and all shapes are equally successful at catching insects.
C. some gazelles are capable of running faster than others, a skill that is partially genetic Faster
gazelles tend to live longer and have more offspring.

Your friend asks you "If evolution is real, why aren't humans perfectly adapted by now! why do
people still get heart disease and cancer and die?"
Which of these would be an accurate response you could give?
A. Evolution only "weeds out" traits that prevent people from passing on their genes. Many diseases are common
in elderly people who are done having children.
B. Humans are a relatively young species. Someday, in thousands of years, humans will be perfect and diseases free.
C. Evolution only acts on genetic traits, and disease like cancer and heart disease have nothing to do with genetics.
 
3. Which statement about evidence for evolution is FALSE?
A. Some organisms have organs that they inherited from their ancestors but do not use
B. Humans have never observed evolution happening because it takes too long
C. Fossils provide evidence of species that once lived on earth but are now extinct
D. Many species share a lot of the same genes, with only slight differences in DNA sequences
