1. Australia has unusual organisms because their evolution for the past 38 million years has been
Rapid
Slow
Isolated from other organisms
Punctuated

If the Neanderthals are not the direct ancestors of humans, is it still possible for humans and Neanderthals to be related?
Yes, because we share a common ancestor
Yes, but only if humans and Neanderthals could have interbred
No, because the human evolutionary tree is strictly linear and without branches
No, because this means that Neanderthals evolved from an entirely different branch of organisms than humans did
Which word does not describe humans?
Ape
Mammals
Amphibian
Primate
Biogenetic law as given by Haeckel states that
ontogeny recapitulates phylogeny
phylogeny recapitulates ontogeny
ontogeny and phylogeny go together
there is no relationship between phylogeny and ontogeny.
What was the most significant trend in the evolution of modern man (Homo sapiens) from his ancestors ?
Shortening of jaws
Binocular vision
Increasing cranial capacity
Upright posture
Which statement best illustrates a rapid biological adaptation that has actually occurred?
Pesticide-resistant insects have developed in certain environments.
Scientific evidence indicates that dinosaurs once lived on land.
Paving large areas of land has decreased habitats for certain organisms.
The characteristics of sharks have remained unchanged over a long period of time.
According to Darwin, the organic evolution is due to
Interspecific competition.
Competition within closely related species.
Reduced feeding efficiency in one species due to the presence of interfering species.
Intraspecific competition.
The neanderthals can be attributed with all of the following characteristics, except
Cranial capacity almost equivalent to modern man
Burial customs
Cave-painting
use of spears as weapon
Which of the following is not an example of molecular evidence in favour of evolution?
Human DNA differs in only 1.8% of its base pairs from chimpanzee DNA indicating phylogenetic relationship.
Amino acid sequence for protein cytochrome C has no difference in human and chimpanzee
A common genetic code is overwhelming evidence that all organisms are related
All embryos of vertebrates develop a row of vestigial gill slits just behind the head
Choose the incorrect statement.
Accumulation of useful mutations through ages has led to the creation of new species of living beings
Genetic variability is lost if a population crashes leading to bottle-neck effect.
According to Darwin, discontinuous variations occur as a result of natural selection.
Genetic variability provides raw material for the operation of natural selection and reproductive isolation.
