Can you give short note on [Tracing Evolution Relationship]........ Google answer and stammers will be reported by me
Answers
Over thousands and millions of years, a bewildering variety of species has evolved on the earth. Among these, some are known and some are unknown to us. The life forms around us range from, tiny ants to tall trees, colorless worms/insects to brightly colored flowers and birds. Understanding and tracking all of them in a fraction of the time, one by one is not a wise choice. We need to group them based on certain basic criteria. Let us have a glance at evolution and classification, tracing of evolutionary relationships and the formation of fossils in detail.
Explanation:
Characteristics assist us to trace the evolutionary relationship between organisms. Evolutionary relationships help us to trace who we are closest to and who is our common ancestor.
A group of entities is similar enough to be thought of together by certain characteristics.
For example, reptiles and mammals. All of them have 4 limbs. The basic structure of their organs is more or less the same, although they utilize it for varied functions. These organs are known as homologous organs. This does not mean that they share the same ancestor.
Some entities seem to be similar, however, the basic structure is different.
For instance, wings of birds and bats. Both of these animals make use of wings for the same purpose, however, their basic structures are different. Such organs are known as analogous organs.
Thus, the analogous and homologous characteristics help in tracking an evolutionary relationship between different species.
