What Parts Of An Organism Are Most Likely To Be Fossilized Why? Soft parts are more likely to decay than hard parts. For this reason, the most common fossils are bones, teeth, shells, and the woody stems of plants. For a fossil to form, an organism must be buried quickly so that any oxygen is
Which Form Of Life Appeared On Earth First? The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things. What animal was alive first? A comb jelly.
What Do You Think Paleolithic Humans Would Be Most Worried About? They had to worry about whether overfishing a lake would deplete a crucial food source or whether a drought would wither up important plants. In order to ensure enough food production for their communities, they worked to manipulate those systems in certain ways, such
Which Organism Has A Better Chance Of Leaving A Fossil A Bony Fish Or A Jelly Fish Explain? Because of this, soft parts rarely become a fossil and only the hard parts like bones, shells, teeth, seeds, and woody stems leave fossils. Therefore, a bony fish is likely to leave a fossil since it has
What Does A Paleontologist Do In A Day? Paleontological research includes working out the relationships between extinct animals and plants and their living relatives. We reconstruct early communities and their environments and try to understand the changes that have led to those of the present day. What are the work hours for a paleontologist? Paleontologists
What Did The First Tetrapods Evolve From? Tetrapods evolved from a finned organism that lived in the water. However, this ancestor was not like most of the fish we are familiar with today. Most animals we call fishes today are ray-finned fishes, the group nearest the root of this evogram. When did the first tetrapods
Which Type Of Organism Do You Think Is Most Likely To Be Preserved One That Gets Buried? Hard parts like bones and teeth are more likely to be preserved. Rapid burial is important in the fossilization process because: It protect a dead organism from physical and biological destruction. Which organism is most likely to be
Which Best Describes The Fossil Record Which Best Describes The Fossil Record? The fossil record provides evidence of a common ancestor to many species. A fossil record provides the confirmation of the typical progenitor and its numerous species. A fossil is known as the remaining parts of a certain living life. The fossil record helps
When Did The First Large Multicellular Organism Show Up In The Fossil Record? Large, multicellular life forms may have appeared on Earth one billion years earlier than was previously thought. Macroscopic multicellular life had been dated to around 600 million years ago, but new fossils suggest that centimetres-long multicellular organisms existed as early as 1.56
Why Are Evidences Important In The Study Of Origin Of Life? Major lines of evidence include DNA, biochemistry, and experiments. Biologists use the DNA sequences of modern organisms to reconstruct the tree of life and to figure out the likely characteristics of the most recent common ancestor Why is it important to know the origin
