Biological evidence of the age of the earth includes _____.

kobusy [5.1K]

Answer;

-Fossil evidence

-Comparative anatomy

-Molecular clocks

Biological evidence of the age of the earth includes fossil evidence, comparative anatomy, and molecular clocks.

Explanation;

-Fossils are critical tools in science because they give us clues to the types of plants and animals that lived on Earth in the past.There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined.

-Comparative anatomy is an important tool that helps determine evolutionary relationships between organisms and whether or not they share common ancestors. However, it is also important evidence for evolution. Anatomical similarities between organisms support the idea that these organisms evolved from a common ancestor.

-Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.

Shtirlitz [24]

Answer:

Option-(True): The methodology used to discover the pattern of evolution among an assemblage of species is based on the assumption of descent with modification.

Explanation:

Evolution and patterns of evolution:

The phenomenon of evolution is very interesting as it can any two different species back to a common origin or ancestors. While the process of evolution does not occur in few years or centuries, as it takes millions of years for any specie to evolve from a less developed form of body or any system to a more complex or advance form.

Now, evolution occurs in many forms or patterns. As it species can originate from a single ancestor or descendant, while the evolution can occur inside the organism may occur in different patterns. These patterns are as follows:

Divergent Evolution:The divergent evolution occurs when the species originated from a single ancestor or descendant results in different forms of organisms. As it brings diversity among the species belonging to same ancestors or origin. For example, the humans and apes.
Convergent Evolution: The convergent evolution takes place inside the number of species when they are originated from the different species but they share the same medium or region to live in and share some of the similar resources between them. For example, The whales are mammals but they too live with the fish species inside the water.
Parallel Evolution:When the evolved organisms or species are related to the different ancestors or descendants, as they share they do not share the same niche(way of life), as the species are unrelated to one another.
