I need all 4 question answered.

Answer 1

Answer1:

Two ways by which organisms can provide for evolutionary evidences are:

1. By comparing the geniting sequences of organisms: this can be helpful in revealing the facts related to their evolutionary relationships. This can be achieved by comparing the similarities of the DNA sequences from the group of other organisms .

2. Fossils: it is an important evolutionary evidence as this can be used for estimating the lineages of organisms which may have developed from long back. Usually the body parts or sediments of remains are collected as a fossil record to estimate the years and information from the site. This gives an idea for developing evolutionary relations and predictability.

Answer2:

Whales are evolved from the land-dwelling animals: the found fossils obtained from the United States and Pakistan by the palaeontologists confirmed this evolutionary evidence. This was estimated and suggested that the first whales were Pakicetus, and they were considered typical land dwellers. They possessed large carnivores’ teeth and had large skulls especially the ear regions were surrounded by the bony coverings. All these together made these whales to swim and to roam on land. The possibility of the timescale of this fossil evidence collected is approximately 47 million years ago.

Answer3:

Some animals can survive in their adulthood for the reasons as: they possess the better adaptation features than other organisms. This can be well explained by the Natural selection process in which organisms thar are better suited to the surrounding environment can survive more where they can meet their requirements and thus, can also produce more off springs as well.

Answer4:

Genetics is very much related with evolution as the genetic variations are an important aspect of evolution .The genetic variations (that occurs at genetic levels or on genes ) are responsible for the changes that makes the organisms and are able to withstand with its environment and it is very much likely to be passed to the subsequent generations via natural selection. These genetic variations when accumulated over years and years (several years) becomes the rawest material for the evolution.
