Speciation and patterns of Evolution

Question 1

what is speciation

Answer 1

process of forming a new species

Question 2

what does patterns of evolution mean

Answer 2

evolution has two different patterns which result in different adaptions over time

Question 3

what is divergent evolution

Answer 3

numerous species develop from one common ancestor, becoming less and less alike over time

Question 4

what is convergent evolution

Answer 4

numerous species that are not closely related but occupy similar habitats resemble each other

Question 5

what are analogous structures

Answer 5

animal structures that perform similar functions but aren’t closely related

Question 6

what are homologous structures

Answer 6

animal structures that have evolved from a common ancestor but now have different uses

Question 7

how could you test if two similar looking species are different

Answer 7

allow them to breed, if they are different their offspring will not be viable or fertile

Question 8

how is speciation, biodiversity and evolution linked

Answer 8

biodiversity is the variation in a species, for speciation to occur there must be variation and when speciation has occurred that means evolution has also occurred
