Answer:

Option A is correct (Alfred Wallace).

Explanation:

Option A is correct (Alfred Wallace).

According to the evolution theory all living species are evolved from a simple life source with the passage of time.

Points of natural selection:

Genetic variation are passed from generation to generation but environment can cause variations too.
Individuals in species have gene variation which is due to random mutation
Those who can not adopt to environment can not have their genes pass to next generation.
Natural Selection is also called as "Survival of the fittest".

Answer: Option A.

Alfred Wallace.

Explanation:

Alfred Russell Wallace was an English naturalist born in January 1823. He independently proposed theory of evolution by natural selection. His scientific ideas encouraged Charles Darwin to work together with him and they both published their scientific ideas in 1858.

Wallace thought that an inferior variety can coexist with another superior variety in the environment, until deteriotion forced the inferior variety to be extinct from the environment and this is totally different from Darwin's view which said that individual with heritable trait are better suited in their environment.

A cloud directly above you is about 10° across. From the weather report, you know that the cloud is at an altitude of 2200 m. Ho

Vikentia [17]

The width of the cloud is : 384 m

<u>Given data :</u>

Cloud altitude = 2200 m

Temperature = 10°

<h3></h3><h3>Determine how wide the cloud is </h3>

applying the equation below

I = d $(\frac{\alpha }{57.3})$

where : I = linear size , d = 2200 m , $\alpha = 10^{o}$

therefore :

I = 2200 ( 10 / 57.3 )

= 383.94 m

≈ 384 m

Hence we can conclude that the width of the cloud is : 384 m

A student argues that two species of birds are the same species because they have similar body structures, similar DNA, and simi

ArbitrLikvidat [17]

<u>Answer:</u>

"The birds have different mating seasons" piece of evidence supports the second student's argument.

<u>Explanation:</u>

The precise timing for bird sets to successfully match varies, and the timing for distinct species develops to give the consequent chicks the best chance of survival. Speciation is the mechanism through which new species are produced. This happens when classes within an individual are separated and diverge reproductively.

Organisms contribute to the same group as per the biological species definition if they can reproduce in order to create healthy, fertile offspring. Group are divided by prezygotic and postzygotic restrictions which prevent mating or producing viable, fertile offspring from each other.
