4. Pitanje 4

   According to Darwin, why do species with few eggs, like the Fulmar petrel, sometimes outnumber species laying many?

   • Small clutches are always hatched faster
   • Egg number only indirectly affects average numbers; protection and survival matter more
   • Birds with one egg never face predators
   • Large clutches cause starvation in all cases

5. Pitanje 5

   What did Darwin say natural selection will tend to cause among the less improved forms of life?

   • Rapid spread to new continents
   • Extinction
   • Immediate hybridisation
   • Identical appearance

   • It never climbs a tree
   • It only eats fruit
   • It builds nests underground
   • It hunts at night

7. Pitanje 7

   Why did Darwin find the neuter (sterile worker) insects such a serious difficulty for his theory?

   • They are too small to study
   • They live only in Africa
   • They never eat
   • Sterile workers differ from their parents and cannot pass on acquired habits

8. Pitanje 8

   Darwin argued that the fossil record shows so few transitional forms mainly because:

   • The geological record is very imperfect
   • Transitional forms never existed
   • Fossils dissolve in sea water
   • Scientists destroyed them

9. Pitanje 9

   What surprised Darwin about pigeon seeds fed to him by experiments, when a pigeon's crop had floated in salt water for 30 days?

   • The seeds had turned to salt
   • The seeds had rotted
   • Nearly all the seeds still germinated
   • The seeds sprouted inside the bird

10. Pitanje 10

    How did Darwin explain the resemblance between whales and fishes in body shape?

    • They share a recent ancestor
    • It is an analogical, adaptive resemblance for swimming
    • Whales are a type of fish
    • It is pure coincidence with no cause
