Core Viewpoint - The BioCLIP 2 model, trained on 2 billion biological images, demonstrates superior species recognition performance and emergent biological understanding beyond species classification, achieving significant advancements in ecological alignment and intra-species differentiation [1][2][5]. Group 1: Model Development and Data Collection - The research team collected 214 million biological images from four major platforms, creating the TreeOfLife-200M dataset, which includes 952,000 different classification labels, making it the largest and most diverse biological image library to date [2][4]. - The model was scaled from ViT-B to ViT-L, increasing the parameter count to facilitate the emergence of new knowledge [4]. Group 2: Performance Metrics - BioCLIP 2 achieved an average accuracy of 55.6% in zero-shot species recognition, outperforming the second-best SigLIP model by 16.1% [5]. - In non-species visual tasks, BioCLIP 2 surpassed common visual models like SigLIP and DINOv2 in habitat recognition, biological attribute identification, new species discovery, and plant disease recognition [8]. Group 3: Emergent Properties - Two emergent properties were identified: 1. Ecological alignment among species with similar lifestyles and ecological significance clustered in feature space, with clearer boundaries as training scale increased [10][11]. 2. Intra-species differentiation, where differences among male, female, and juvenile forms of the same species are distributed orthogonally to inter-species differences, improving with larger training scales [12][14]. Group 4: Training Scale Impact - Experiments showed that increasing training data from 1M to 214M consistently improved performance in non-species visual tasks and enhanced the orthogonality of intra-species differentiation [15].

Group 1 - The core viewpoint of the article highlights the publication of the "Flora of Kenya: Volume 4 Orchidaceae," which is a significant outcome of Sino-Kenyan scientific collaboration [1] - The compilation of the "Flora of Kenya" is a large international cooperation project led by the Sino-African Joint Research Center, the Wuhan Botanical Garden of the Chinese Academy of Sciences, and the National Museum of Kenya [1] - The project aims to document all vascular plants in Kenya, with a total of 31 volumes planned, covering 223 families, 1,773 genera, and over 7,000 species of plants [1] Group 2 - Since its establishment in 2013, the Sino-African Joint Research Center has focused on biodiversity research, ecological environment protection, disaster warning, and modern high-value agriculture, achieving a series of results [2] - The center has recruited and trained 320 master's and doctoral students from African countries and has established regional cooperation offices or joint laboratories in several African nations, forming a cooperative network for scientific research and talent cultivation [2]
