The fossil record is biased because...Actually, this bias is only perceived; older eras had completely different body plans whichmakes it look like a lot of fossils are missing, while instead they existed.O Fossilization only happens under dry, arid conditions, which is most common in limited,desert like conditions.O The decomposition of an organism needs to slow down to increase chance of fossilization,which only happens under certain conditions.O Only organisms living in the deep ocean have a chance of fossilizing, because those areideal conditions.29InTO

One benefit of the fossil record isa. that hard parts of bodies are more likely to fossilize.b. that fossils can be dated.c. its completeness.d. that fossils congregate in one place.e. All of these are correct.
What is a transitional fossil? Transitional fossils were poorly adapted to their environments. O Transitional fossils have features that are intermediate between ancestors and descendants. Transitional fossils only existed for a short period of time. A transitional fossil is in the middle of a direct lineage stretching from ancient forms to organisms alive today

Scientists on a fossil expedition in the Florida Everglades excavated an area with four strata (layers). Z Hawthorn Group Y Tamiami Formation X Undifferentiated sediments W Miami Limestone The Everglades W X Z They found vertebrate fossils in all four strata: 124 fossils in the Miami Limestone, 75 fossils in the Undifferentiated sediments, 138 fossils in the Tamiami Formation, and 62 fossils in the Hawthorn Group. The scientists concluded that the Hawthorn Group contained the oldest fossils. Is this a valid conclusion? Yes. The Hawthorn Group must contain the oldest fossils because this layer has the smallest number of vertebrate fossils. CYes. The Hawthorn Group must contain the oldest fossils because it is the lowermost layer of soil and rock excavated by the scientists. No. The Tamiami Formation must contain the oldest fossils because it contains the greatest number of vertebrate fossils discovered. No. The Miami Limestone must contain the oldest fossils because it is the uppermost…

Why is the study of biogeography an important tool in explaining how species have evolved? * It shows us the relationship between a species' environment, and how they have evolved It shows us how the DNA has changed from one generation to the next It shows us how the bone structure of organisms has changed over time It shows us how old the Earth is Ce @ $ % 7 e t d gh #の
