A
Hairy, walked like gorillas and chimpanzees.

B
Existed 15mya.

B
Fossils of Homo erectus were discovered in Java in 1891.

C

A
Russia, England, non-living inorganic molecules.

B
England, Russia, living organic matter.

Question 4
1 / -0

Analysis of the skull of man and apes is given below. Select the correct option from the following:

A
Skull of R is more like P than Q because they have common ancestors named Dryopithecus

B
Skull of P shares similarities with R and not with Q

C
Skull of Q is more like R than P because they have a common ancestor named Ramapithecus

D
Skull of Q is more like P than R because they have a common ancestor named Dryopithecus
Question 5
1 / -0

Hardy Weinberg equilibrium is affected by?

A
Natural selection

B
New mutation

C
Genetic drift

D
All of the above
Solution
- If a population is in a state called Hardy-Weinberg equilibrium, the frequencies of alleles, or gene versions, and genotypes, or sets of alleles, in that population will stay the same over generations (and will also satisfy the Hardy-Weinberg equation). Formally, evolution is a change in allele frequencies in a population over time, so a population in Hardy-Weinberg equilibrium is not evolving.
- The 5 major factors the effect Hardy Weinberg Equilibrium are (A)New Mutations (B) Recombinations during Sexual Reproduction (C) Genetic Drift (D) Gene Migration (Gene Flow) (E) Natural Selection.
- Hence Hardy Weinberg equilibrium is affected by Natural selection, New mutation and Genetic drift.
- So, the correct answer is 'All of the above'.
Question 6
1 / -0

According to our reading, how did George Cuvier account for extinctions in nature?

A
Extinctions never occur--there are unexplored parts of the globe where organisms that appear to have gone extinct may still live.

B
Extinctions occur when the slow adaptation of organisms over time to their environment is not quick enough to help them respond to changing conditions.

C
Extinctions occur at random, they do not reflect God's will.

D
Extinctions are due to catastrophic events.
Question 7
1 / -0

Which of the following must increase over geological time according to evolutionary biologists?

A
Size.

B
Complexity.

C
Speed of evolutionary processes such as mutation.

D
All of the above.
