Answer:

The correct answer is presence of cones.

Explanation:

Pine trees have special structures called "pine cones". These produce and fertilize the seeds that are later dispersed all over the ground when these cones fall. Pine trees contain both male and female cones, and the ones that produce pollen are the male cones. This pollen needs to fall on a receptive female cone for the embryo to grow (<em>it usually takes 2 years</em>). Each grain of pollen contains the genetic information of the pine tree of which the cone hangs. Animals such as squirrels also help in the dispersal of seeds.

HELP ASAP!!!! All life on earth has descended from a common ancestor this theory was accepted when
kap26 [50]

Answer:

A. A majority of scientists agreed with it

Explanation:

The famous theory called the theory of common descent, states that all the living organisms of the earth have arisen from a common ancestor. This notion was first proposed by a French mathematician,Louis Maupertuis duirng 1740s who was of the view that all organisms had a single ancestor and evolutionary process with the passage of time resulted in the specie diversification.

After that, in 1790s another philosopher Immanuel Kant, suggested that all organisms seem to have a common ancestor. In the same period of 1790s, another scientist , Erasmus Darwin who was the grandfather of Charles Darwin also suggested that all the organisms might have a single ancestor who went through the process of evolution to bring all the majesty into life.

Charles Darwin was the first scientist who worked on this notion for alot of time and proposed the theory of common descent,in his book, On the Origin of Species.

After it, many scientists got agree with this theory such as,  Vernon Kellogg in 1907 and T. Ryan Gregory in 2008 and many others explain that no reliable observations exists which contradicts the theory of common descent.

Therefore, option A is the best option.

Hope it helps!
