Group of answer choices

stabilizing selection

intersexual selection

natural selection

intrasexual selection

"An individual elephant stretched out its trunk to eat and drink; its offspring inherited long trunks as a result." This statement reflects the ideas of:

Group of answer choices

Jean-Baptiste de Lamarck

Aristotle

Charles Darwin

John Henslow

Natural selection is based on all of the following except:

Group of answer choices

individual organisms adapt to their environments and, thereby, evolve

heritable differences exist within populations.

not all organisms are equally likely to survive

individuals who survive longer tend to leave more offspring than those who die young

Answer 1

1.intersexual selection -males have beautiful rainbow manes to attract the females and have better chance at mating

Others are false as

Intrasexual selection happens between the same sex organism

Natural selection happens when the favourable variation is inherited

Stabilizing selection happens when the heterozygotes or intermediate phenotype is selected

2.jean baptiste de lamarck gave the theory of use and disuse (physical characteristics which are acquired during lifetime of a parent are passed to offspring )

Others are false as

Charles darwin gave the theory of natural selection

Aristotle developed the classification system of plants and animals

3.natural selection is not based on the adaptation of the organism to environment and evolution

In natural selection theory variation is already present in the population and some variations are advantageous over others allowing those individuals to survive longer and reproduce more leading to selection of those advantageous individuals overtime
