What are two reasons why many organisms never become part of the fossil record?
Many organisms have soft bodies that decompose quickly after death, leaving no trace behind. Additionally, many organisms live in environments that are not conducive to fossilization, such as areas with high rates of erosion or volcanic activity.
How is the theory of evolution supported by fossil evidence?
When we examine the fossil record we see that the Earth has not always had the same living organisms living on it that it has today, but rather, there have been many changes, some gradual and some abrupt, over the past few billion years, and those changes show progressive alterations of exactly the kind that evolution would be expected to produce. The fossil record tells us that yes, life has evolved.
Do most animals and plants that once lived on Earth have left fossil evidence?
No, most animals and plants that have lived on Earth do not leave fossil evidence. Fossilization is a rare process that only occurs under specific conditions, so many organisms decompose before they can become fossils. This is why the fossil record is incomplete and biased towards certain types of organisms.
Why cant you find many single-celled organisms as fossils in rocks?
Single-celled organisms lack hard parts like shells or skeletons, making it difficult for them to leave behind fossils. Soft-bodied organisms are less likely to be preserved in the fossil record compared to organisms with hard parts, like shells or bones. Additionally, single-celled organisms are more likely to be broken down and decomposed before they have a chance to fossilize.
How is the fossil record like a jigsaw puzzle?
Because we have quite a lot of evidence of prehistoric life and we just need to put together what we have and know like a jigsaw to make a clear picture. However many pieces are still missing as fossilisation is quite rare and many species of life will not have been preserved. Pieces are also missing because we have not found all of the fossils on earth yet as we have not had the technology and time to yet. The fossil record is also like a jigsaw in the way that one little piece of evidence can just put everything together and make things much more clear.
What is one reason why the fossil record is incomplete?
The fossil record is incomplete because not all fossils have been discovered. In actuality it is unlikely that all fossils will ever be discovered given the hit and miss nature of fossil discovery which usually occurs through educated guess work. The fossil record will likely never be complete.

Why did the earliest organims in the fossil record start off single celled?
It took many years of evolution for complex, multi-celled organisms to develop. Single celled organisms were the first that were around to be fossilized.
The fossil record is not complete because?
The fossil record of all species is not complete because the circumstances for fossils to occur is very rare. There must be a special type of sediment, a special type of death (not partially eaten). Therefore, not all species or mutations can be accounted for, however, there are documented fossils for most species or at least close relations
The fossil record is incomplete because?
The fossil record is incomplete because: A.) very few organisms were preserved as fossils. B.) organisms tend to decay before becoming a fossil. C.) animals with hard parts are preserved more easily. D.) geological processes may destroy fossils. E.) all of these. ALL OF THESE!

How many years did dinosaurs roam the earth according to fossil record?
I don't know by fossil record but I have a book called walking with the dinosaurs and it said 220 million years ago

How many years ago were protists first found in the fossil record?
Protists were first found in the fossil record around 2.1 billion years ago.
How many missing links have been found in evolution?
All fossil found to date were missing link. Missing link is a non-scientific term describe new found transitional fossil. Any single fossil found and placed along the line of evolution would yield 2 new missing link mathematically.
What are some evidences of evolution?
the fossil record of change in earlier speciesthe chemical and anatomical similarities of related life formsthe geographic distribution of related speciesthe recorded genetic changes in living organisms over many generations
How does the fossil record evidence support the modern theory of evolution?
Answer 1For Example, You find a fossil of a creature from a certain timeline, then you find the same creature with some changes in a timeline later than the previous and if you have enough fossils you can see how the organism appears at its earliest place in the fossil record( some organisms only appear in the fossil record once they have evolved in a way that makes fossilization possible eg shell, jellyfish are very rare in fossils because they are mostly water) and see the organism change over time into a completely different animal through a series of consecutive glimpses of the creature.Answer 2The absence of transitional forms (fossil record) is an insurmountable hurdle for all evolutionists.Answer 3The fossil record, with its many diverging progressions of traits and morphological intermediates, illustrates the changing of life forms as they diverge from their common ancestors towards more modern forms, matching seamlessly the nested hierarchies of modern morphology. Even without the fossil record, we would have had a pretty good picture of our evolutionary past - with it, we can give shape to the forms that came before us.
