This specimen suggests that is not true.
That surprisingly human specimen suggests that H. ergaster may have been the direct ancestor of the hominins that left Africa for Eurasia about 1 million years ago.
Analysis of the specimen suggested that the animal belonged to a previously unknown group of primitive European sauropods.
However, the mean microcrack length was uniform across the specimen, suggesting that microcrack length is limited by microstructural features.
The Triceratops pelvis shows that heavy biting was certainly within their range of behaviour and capabilities, but a more intriguing specimen suggests that they could be delicate and selective feeders.
The locks are taken from the manes of, among others, Charlotte Brontë, Elizabeth Barrett Browning, Leigh Hunt, William Makepeace Thackeray, and Walt Whitman, whose frizzled white specimen suggests that he may have suffered from the dreaded disease cheveux incoiffables (Uncombable Hair Syndrome, first identified in 1973).
Moreover, each elongated specimen consists of two blastomeres inside the sculptured capsule, and the geometric relationship of the two blastomeres in each specimen suggests that these specimens probably represent cleaving embryos during different phases of cytokinesis.
Microscopic examination of the resected specimen suggested that the tumor invaded to submucosal layer and showed no lymph node metastasis.
Spindle cell carcinoma and metaplastic carcinoma were possible, but the histology of the tumor was similar to that observed in the left lung biopsy specimen, suggesting that the lesion had the same origin as that of the lung tumor.
1– 3 The presence of tumor cells at the surgical margin of the resected specimen suggests that residual tumor cells may remain in the tumor bed.
