make a comparative table that shows of animals evolved
Answers
Answer:
The animal kingdom contains multicellular eukaryotic organisms with heterotrophic mode of nutrition.
They are classified in to Chordates and Non - Chordates based on the presence of Notochord, a mesodermal embryonic tissue that develops into vertebral column ( backbone ) in an adult.
The Non Chordates do not have notochord or vertebral column. Hence, are also known as Invertebrates.
The invertebrates are further classified in to10 Phylums which are attached in the image.
Explanation:
When we talk about evolution, the prokaryotic organisms like plants and animals are of most recent origin. They owe their origin to endosymbiosis. In this process one cell ingests the other but fails to digest it. Plants and animals draw their energy from, which are considered to be the powerhouse of the body. There is much evidence to show that mitochondria evolved from free-living bacteria; their ribosomes are similar to bacteria. Hence, we can say that plants and animals owe their evolution to bacterias.
