Question

Which is the most reliable evidence for evolution and why?

Answer 1

Hint: Evolution is the change within the physical characteristics of a species over numerous generations and it depends upon the method of survival. The theory of evolution is predicated on the thought that each one species is related and progressively changes over time.

Complete answer:
The evidence of evolution is one of the elemental keystones of recent biological theory. It is the sole way that may prove all the proposed theories of evolution. We have a number of evidence to prove biological evolution namely comparing DNA, fossils, comparative anatomy, and embryo development patterns. But Comparing DNA is the most reliable evidence for evolution as At the most basic level, all living organisms share:
-The same genetic material (DNA)
-The same, or highly similar, genetic codes
-The same basic process of gene transcription and translation)
-The same molecular building blocks (amino acids).
These shared features suggest that each one of living things is descended from a standard ancestor, which this ancestor had DNA as its genetic material, used the ordering, and expressed its genes by transcription and translation.

Additional information:
Evolution is the progressive alteration in inherited traits over an outsized span of time, usually over generations. Evolution has created huge biodiversity. Natural selection, genetic drift, and speciation – of these factors shaped biodiversity.
The other evidence for revolution are-
Fossils: they are the remains of the non-degraded parts of living beings present inside the rocks. The layer from which the fossil is renewed determines the age of the fossil. The fossils found deeper down are older compared to those found within the upper layers. They give a thought of the condition of the world they’re in a specific era. The study of fossils is called paleontology. Thus, fossils are called paleontological evidence.
Comparative Anatomy: It explains that a lot of organisms have an equivalent ancestor and lots of different organisms evolved as a result of survival or genetic drift. Two sorts of anatomy were observed, namely homologous organs and analogous organs.
Embryonic Development: The embryos of varied species show a similar structure to a particular period of gestation. For example, the embryos of humans, pigs, reptiles, and birds exhibit related embryonic development. They become the respective species as they grow. This again shows common ancestry.

Note: Nowadays, we can trace the evolutionary relationships between species easily by using fossils, DNA sequences, and palaeontological excavation, etc. It is believed that human evolution began in Africa. The earliest genus of Homo to be ever found is Homo habilis, which lived around 1.75 million years ago.
