a) …are identical to those of their parents

b) …are not identical to those of their parents.

c) ….are more similar to their cousins than their parents

d) …have such great variation that speciation is possible in every generation

22) Charles Darwin is best known for:

a) formulating the concept of Natural Selection in his book “On the Origin of Species”

b) breeding finches to study the patterns of Mendelian inheritance

c) Formulating the concept of competition and lack of resources for populations’ capacity to reproduce

d) noting the movement of the contiwnents and the fact that they were once joined.

24) Humans are biocultural creatures, and as such:

a) biology is only part of our parenting, we have a drive to pass on “who we are” through more than just our DNA.

b) adults who are not parents can have much to offer the next generation

a) other human populations on earth have no other archaic human DNA

b) other human populations on earth have similar percentages of other archaic human DNA

c) Neanderthals never lived in sub-Saharan Africa, so there is no Neanderthal DNA there.

d) both b and c are correct

e) none of the above are supported by Paabo’s research.

Answer 1

21. Due to meiosis, while all of a person’s chromosomes come from their parents, all of their chromosome b) are not identical to those of their parents.

Daughter cells and chromosomes present in progeny are identical in mitosis as here diploid cells are separated into two new diploid cells but in meiosis daughter cells and chromosomes are not identical as diploid cells are separated into four haploid cells. in meiosis, number chromosomes are also half and due to crossing over in meiosis, they look different than parent chromosomes.

22) Charles Darwin is best known for: a) formulating the concept of Natural Selection in his book “On the Origin of Species”

Charles Darwin was a scientist and naturalist who proposed the theory of evolution where he told that species survived through the process of natural selection where species which are adapted to changing environment survived while others failed. he published a detailed explanation of this theory of Natural Selection in his book “On the Origin of Species”.

24) Humans are biocultural creatures, and as such: a) biology is only part of our parenting, we have the drive to pass on “who we are” through more than just our DNA.

biocultural is a view that humans are unique in biology and culture interact so that each influences the other in shaping human behavior not just through DNA. its relationship between culture and biology.

12) Wallace is known for: a) coming up with the same concepts as Charles Darwin and sending them to him for help in publishing them.

Wallace was a naturalist who independently proposed the theory of evolution by natural selection by collecting more than 100,000 insects, birds and animal specimens. and in 1958 Wallace and darwin produced joint scientific journals. he helped darwin to publish his the origin of species
