What are the 5 types of evidence for evolution?
Evidence for evolution

- Fossils. …
- Direct observation.

Changing environments and ecosystems were driving the evolution of horses over the past 20 million years. … “According to the classic view, horses would have evolved faster in when grasslands appeared, developing teeth that were more resistant to the stronger wear that comes with a grass-dominated diet.

What is the strongest evidence of evolution?
Similar DNA sequences are the strongest evidence for evolution from a common ancestor.
What is the best evidence for evolution?
Perhaps the most persuasive fossil evidence for evolution is the consistency of the sequence of fossils from early to recent. Nowhere on Earth do we find, for example, mammals in Devonian (the age of fishes) strata, or human fossils coexisting with dinosaur remains.
