Summary
A deformed dinosaur leg bone reveals the first confirmed malignant tumor in a dinosaur. This paleontological discovery may help identify genetic causes of bone cancer in humans.
Area of Science:
- Paleontology
- Oncology
- Paleopathology
Background:
- A 76-million-year-old fossil revealed a deformed leg bone, prompting investigation into its cause.
- Histological analysis confirmed the presence of a malignant tumor within the bone structure.
Discussion:
- This finding represents the first definitive histological evidence of cancer in a non-avian dinosaur.
- The tumor's characteristics provide insights into the paleopathology of dinosaurs and ancient diseases.
Key Insights:
- The fossil bone exhibits clear signs of osteosarcoma, a malignant bone cancer.
- This discovery pushes back the earliest known occurrence of such a tumor in the fossil record.
Outlook:
- Further study of this dinosaur osteosarcoma could illuminate the evolutionary origins of cancer.
- Understanding the tumor's biological drivers may offer new avenues for research into human osteosarcoma genomics.

The Fossil Record
26.8K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

What is Evolutionary History?
42.5K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

Gene Duplication and Divergence
7.6K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

Radioactive Decay and Radiometric Dating
36.2K
Radioactivity is a spontaneous disintegration of an unstable nuclide and is a random process, as all the nuclei in the sample do not decay simultaneously. The number of disintegrations per unit time is called the activity (A), which is directly proportional to the number of nuclei in the sample. The decay constant (λ) is an average probability of decay per nucleus in unit time.

Next-generation Sequencing
97.0K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

Global Climate Change
28.3K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
