How does molecular evidence support evolution
WebMethods such as radiometric dating —measuring the amounts of natural radioactive atoms that remain in certain minerals to determine the elapsed time since they were constituted—make it possible to estimate the time period when the rocks, and the fossils associated with them, were formed. WebAnswer (1 of 16): Similarity in genetics of organisms or its molecular underpinnings is a fact. However, the interpretation that this is point blank proof of evolution is myopic at best. It's …

WebJun 19, 2024 · One piece of evidence that supports the idea that dolphins and humans come from a common ancestor is their limbs. Dolphins have front flippers that help reduce friction in water as they swim. However, by looking at the bones within the flipper, it is easy to see how similar in structure it is to the human arm. WebThe earliest fossil evidence of life. The earliest evidence of life on Earth comes from fossils discovered in Western Australia that date back to about 3.5 3.5 billion years ago.
